I recently completed, well almost...the customer (aka my dear wife) wants me to make a set of doors to hide the TV when not in use, of a large wall unit/entertainment center and will share details of its design and construction, as well as the problems I encountered along the way, how I addressed them, and my suggestions for anyone who chooses to make a similar project.  The entertainment center comprises four separately constructed cases that are fully finished on 3 sides so they can be used together or separately or with other furniture pieces.  I say "almost completed" because doors to hide the TV when not in use are still under design considerations and location of suitable veneer and accent wood, and I need to make and install the dividers within the fully dovetailed drawers that are behind the glass doors.  Most of the major challenges I enountered were due to working alone in a small overcrowded single car garage/shop.

The cases are constructed of double sided red oak veneered plywood with solid oak edging, most of which was attached using dominos.  A few pocket screws were also used.  Each of the tops has xenon lamps flush mounted within.  Lacewood was used as an accent strip in the valences.

Construction involved use of TS 55 and multiple MFTs (old style), Domino, OF 1400, RO 125, ETS 125, LS 130, CT 22, LR 32 Hole Drilling set, Festool Side Stops and shopmade side stops with extended range, conventional router table, a spaced apart double MFT 800 table setup for routing with MFS template, Kreg pocket jig with shopmade dust collection hose adapter, and Fuji HVLP spray finish equipment.

Also described in detail the finishing schedule I used (including why), along with some unanticipated problems encountered and how I addresed them.  A combination of solvent and water-based materials were used.  The final finish coats are water-based lacquer from Target Coatings (Oxford brand).

Here are a few photos of the completed unit.

And what my wife to rearrange those symmetrically arranged, adjustable shelves.  I guess I'll have to go build more bookcases!

To come later: a modern design coffee table with granite top.  The stone company called me yesterday to say the top is finished.  I'm still thinking about design ideas and alternatives, and how to deal with the weight of that top and the table which will be sitting near the middle of a room with 20ft clear span joists.  I think they are strong enough, but I am concerned about deflection, turning the floor into a large, shallow bowl.

Thanks, Todd.  I just completed (well, almost) setting up a gallery on FOG from which I intend to continue writing a detailed description of my design and construction efforts.  Unfortunately, I do not know how to use SketchUp so my drawings and cut lists and notes are hand drawn on paper, and my HP 6110 all-in-one machine conked out recently.  I was hoping to be able to scan and post a PDF of the drawings and cut lists.  Maybe someone on FOG can teach me how to best do this.  The PC aspects of this project are proving much more of a challenge to me than the woodworking and finishing issues!

Today I ordered the granite top insert for a coffee table that will complement the entertainment center.  The general design is a square table, about 44" x 44" x 14" to 16"H.   If you can envision a truncated, inverted pyramid,  each layer formed of a square oak perimeter frame, corbled out towards the top you understand the concept.  The top will have an oak border frame and the granite will be set proud of the frame, assuming I don't throw my back out trying (with help from my son) to set the stone in place.  The slab from which the top is to be cut is about 1 1/4" thick and the vendor will not machine it thinner for me.   I contacted some out of state vendors that had materials of interest, but they will not ship to me.

Construction of Console for Entertainment Center 

Inspiration for the design of this entertainment center including some of the Console features was taken from a photo of a system shown to my wife by a decorator.  That unit was only available in Jatoba, only in one finish which was too dark to match the stained oak wall and trim in the living room in which the unit was to be located.  The dimensions of that commercially available entertainment center/wall unit weren't quite right, either, they were too short.  Initially, my wife wanted a "cubist" appearance when viewed straight on from the front, she wanted the shelves and partitions to form an array of nearly square boxes of nearly equal size as shown in the commercial unit which had fixed shelves of solid panels.   I changed that to adjustable shelves with glass insert panels, and made a couple of extra shelves with solid panels.  To complement some other furniture we have, the doors were fitted with beaded glass panels.  I made them so the panels can be easily replaced, if needed or desired.  You could substitute a different type or color of glass or even leaded glass, or panels of contrasting or figured wood or metal such as one of the many decorative copper panels that are available.  Architectural supply catalogues and websites are good sources of ideas and materials for your consideration.  I only regret that I did not happen upon any of these sources until my project was almost completed, too late to make many changes.

For stability, the sides, top, partitions and shelves of the Console are made of plain sliced, red oak veneered plywood edged with solid oak.  To add a little visual effect, on the outside surfaces, the front and back edging of the sides stands 1/4 inch proud of the plywood panels.  The front edging of the side panels also stands 1/4 inch proud of the inside surface of the plywood panels, but the back edging is flush with the plywood.

The Console is designed to be used with a flat screen TV and common DVD player, and Warner Cable (Scientific Atlanta) DVR, with storage in  four drawers behind the doors for DVDs and CDs.  The Console is 52 inches wide, 19 inches deep and 24 inches high.



To make the panels, 3/4 inch veneered plywood had to be ripcut and then cross cut.  The widths of the ripped pieces ranged from 12 inches to 17 inches (and for the backs of the Bookcases more than 27 inches).  For many of the needed components, multiple ripped panels were needed.  To help ensure uniformity of width of the ripped panels, I made a pair of extended range Side Stops as shown in the  photo below.



As you can see, these are really nothing more than an adaptation of what Festool already offers.  The heads of these stops are the same as those supplied with Festool's Edge Stops (Item #485758) that are marketed for use with Festool's LR 32 Hole Drilling set (Item #583290).  If you have the Hole Drilling Set you can substitute longer rods to extend their range.  Hexagonal aluminum rods having a 5/8 inch dimension across the flats would be nearly perfect.  But since I did not have access to any of these, I substituted a pair of 3/4 inch diameter dowel rods, and ground a flat on one end of each rod to enable it to be gripped by the top plate of the head of the stops.  Although I have the Hole Drilling set, I chose to purchase additional pieces enable use of a pair of Festool Limit Stops (Item Number 485827) I own for this purpose.  Thus, I don't have to recalibrate my Side Stops for use with the Euro 32mm system.  The bodies of the Limit Stops are identical to those of the Side Stops.  All that is needed to complete conversion of a Limit Stops is a  top plate, a 6mm machine screw and square nut.  Bob Marino worked with me to obtain the correct OEM hardware plates, but suitable plates can be made easily from aluminum plate and Imperial screw parts.



For the adjustable End Stops, I simply bored a 3/4 inch hole through a couple of blocks of hardwood, then bored and tapped them to receive a 6mm machine screw (so I can easily tighten them with my "Toolie Tool" or any Phillips screwdriver).  It is important that the 3/4 inch bore through these End Stop blocks be perpendicular to the face that will be in contact with the workpiece to be cut, so use a drill press if available.   If you have not tried it, you may be surprised how well hardwood accepts being tapped with ordinary metal working taps.  Metric taps are available at many hardware stores.  Mine are Ace brand and were only a few dollar each.  The main difference compared to tapping metal is to more greatly undersize the bore to be tapped.  A little boiled linseed, tung or other curable oil finish on these wooden threads will serve to strengthen them, but it is not necessary.  After boring and tapping the End Stops, I used a bandsaw to cut through the short end of each block, then made at least a pair of additional kerfs in the blocks beyond the main bore.  These kerf cuts allow the block to be snugged in position against the dowel rods without splitting the blocks.



To set these Shopmade Side Stops for ripping wide (or narrow) strips off a sheet of plywood, I simply mark the ends of plywood at the desired width, then set the rubber edge strip of the Guide Rail on the mark.  Then I mount the Side Stops adjacent to each other at one end of the Guide Rail and adjust both of them until the End Stops (wooden blocks) are in contact with the reference edge of the plywood sheet.  After setting the Side Stops, I move one of them to near the opposite end of the Guide Rail.  Then I reset the Guide Rail on the sheet to be cut, then make the cut.  To setup for the next cut, the Side Stops are again mounted near to the opposite ends of the Guide Rail, the Rail is positioned on the sheet using the previous cut line as a reference.  The Side Stops are then removed, and the next cut made with the TS 55 saw.  I was surprised how close to exactly the same width the ripcut panels were. 

Here is a photo of a stack of ripped plywood panels for this Entertainment Center project, not just those for the Console which did not require as long pieces.  It turned out that I actually needed more than these to complete this project.  That was not a problem, I simply used one of my previously cut pieces to reset my Shopmade Side Stops to the needed width and cut additional strips for the shelves of the Bookcases and TV Cabinet.



Although I am focusing on construction of the Console in this section, in practice I ripped nearly all of the plywood sheet panels that I would need at this time.  Due to my small crowded shop, I used an old workbench to store my inventory of 10 sheets of plywood.  I ripped many of those sheets right on that stack.  Due to my working alone, most of the time I did not move the sheet to be cut other than to lift it up to slip panels of foam insulation board underneath prior to cutting.  After supporting  the sheet to be cut on panels of foam insulation board, the Guide Rail was positioned on top for the cut.  At first I clamped the ends of the Guide Rail, but eventually came to trust it to stay in position which it did.

The front edges of the side panels are edged with 1inch thick by 1 1/4 inch wide solid oak located and fastened with dominos and glue.  The back edges of the side panels are edged with 1 inch thick by 1 inch wide solid oak strips similarly dominoed and glued.  On the insides of the side panels, the back edge strips are flush with the inner surface of the plywood, whereas in the front, the edging overhangs the panels by 1/4 inch both to the outside and to the inside.

My setup for this is shown in the following photos.   It is a pair of Guide Rails joined by Festool connectors, clamped onto a long board of 5/4 oak of the same stock to be ripped into narrow strips.  In the photo is a 3000mm Rail joined to a 1400mm Rail spanning multiple tables.  Most of my 5/4 oak boards were 10 to 12 ft long.  So I ripped a straight edge on one of them using the TS 55 and Guide Rail, then ripped a strip 1 inch wide and another 1 1/4 inch wide.  I used pieces cut from the the 1 inch strip as a gauge block to set the "fence board" clamped underneath the Rail back the desired 1 inch distance.





Below is another photo showing my TS 55 positioned near the end of the Guide Rail, ready to rip a narrow strip from off the shorter board whose edge is abutted against the longer board that is clamped under the Guide Rail.


One caution is in order when using this technique.  As the stock board being ripped into strips becomes narrower, it may warp due to internal tension that is released as the strips are cut.  When I encountered this problem, I used my jointer to recreate a straight edge to abut underneath the Guide Rail.  If you don't have a jointer, you can set the crooked edge just barely under the Guide Rails and rip a fresh straight edge.  In this case, be sure to keep the board to be cut from moving during the ripcut since it will not be captured under the Guide Rail.

More to come!

Thanks, Todd.  I've found the 3/4 inch oak dowels have been stiff and straight enough, and have remained so.   I selected them from the stock at the store by rolling them on the floor to find truly straight ones with close grain rings.  I just noticed that my text note within the photo reads "5/8 inch" dowel.  It should have read 3/4 inch!  I created a flat on the end that is gripped by the Festool Stop using a belt sander.  The black marker line was used as a visual aid while sanding the flat.

That's a very well designed and built unit Dave.  I am enjoying reading your account of the construction and I look forward to reading more.

Based on what I have seen so far, I think that your project is a strong contender for this month's contest.

Chapter II - Entertainment Center Construction

Cross-Cutting the Previously Ripped Stock

After ripping the plywood sheets for the panels and ripping the 5/4 oak boards into narrow strips, I needed to crosscut these into the various lengths needed.  For this I used my MFT 1080 and TS 55 connected to my CT 22E through an Oneida Dust Deputy.



Placement of an MFT 800 to the left of my MFT 1080 equipped with fence of crosscut Guide Rail provided ample support for the longer pieces to be crosscut.  These two MFTs were connected using Festool's metal connectors (Item #484455).  Although the longest pieces for the Console were only 52 inches long, those for the Bookcases were nearly 7 ft long.   For support to the right side of the saw of the stock to be crosscut, I set up an auxiliary table by simply laying an old flush hollow core door on a pair of sawhorses.  I got lucky because the elevation of that auxiliary table nearly matched that of the MFT top.  Some of the strips to be crosscut were ~12 ft long and while many of the pieces to be crosscut from them were only a little more than 1 ft.



The photo immediately below shows some of the crowded conditions in my small shop.  I was against the overhead door when taking this photo.



Needless to say, this lengthy arrangement of MFTs and auxiliary table took up a lot of floor space in my 15 ft X 25 ft garage/shop which also houses a table saw, bandsaw, Shopsmith, dust collector, tool chests, welding equipment, spray equipment, car repair equipment and much of my wood stock, including all used in construction of this entertainment center, and more for use in making substitutes for Systainer-Ports.  Although I have a basic Hitachi CMS, sometimes the shop was so crowded with stock and work in progress that I had to resort to an ancestor of the Kapex.




As you can see in a photo above, to protect the top of my MFT 1080, I use a 2 ft x 4 ft piece of quarter inch plywood, which I clamp to the top.  To aid in aligning the stock to be crosscut, I clamp a piece of scrap wood to the right of the MFT fence and in-line with it.  This also seems to slightly improve capture of the sawdust as the saw blade passes through the far end of the stock being crosscut.  I recommend using a board that is somewhat wider than is shown in the photos so the blade kerf ends within the auxiliary fence.  Note also that I moved the MFT aluminum fence about an inch to the left after cutting a nice 45 degree mitre through it during an earlier project.  (The picture frames came out quite well.)  Such mitre cuts will be needed later when making the valences on the Bookcases.



Here's another view from the backside of the MFT:


After working with the long board and panels involved in making this project, I realized that an even better Multiple MFT setup would have positioned another MFT to the right side of the MFT equipped with the cross cutting Guide Rail.  Joining a pair of MFTs would enable aligning the fences on both so the long stock to be cut would also be guided into alignment by the additional section of fence to the right of the main MFT fence.  I don't (yet) own another MFT with a fence.  But any MFT could be fitted with a fence, e.g. using a Squaring Arm as a fence.

There has been much discussion on this forum about squaring up the fence to Guide Rail on the old style MFT 1080 and MFT 800, and the nuisance of having to re-square it every time it is removed from the MFT and replaced.  My experience confirms that a recheck of squareness should be made every time, if true 90 degree crosscut accuracy is needed.  But there is an easy, quick solution to this issue.  Get or make a large (12 inch or greater) precision square and keep it handy by the MFT.  I chose an 18 inch aluminum 45-45-90 degrees triangle carpenter's square from Woodpeckers; although pricey at about US$ 100, I have found it useful for many tasks involved in making this Entertainment Center, and strongly recommend getting a this or an equivalent product.    I found this large square invaluable for use in my unorthodox technique for use of the LR 32 and Hole Drilling set which will be discussed later.

Insert photo of Large Square on MFT - or look at Woodpeckers website.

To square up the MFT fence to crosscut Guide Rail, I lower the hinged end of the Guide Rail so that it rests on the aluminum fence, place a scrap of one-half inch plywood under the Rail for support along its length, lower the Guide Rail and adjust the height of the tab holder nearest the operator so the tab is fully engaged in the slot underneath the Rail to prevent side movement of the Guide Rail.  I do not setup the Stop bolts on the side rails of the MFT to apply any sideways tension within the Guide Rail when the end near the operator is engaged in the tab, but some MFT users recommend that procedure to remove any play when the Guide Rail is down in the tab.  Then I lay the Woodpeckers precision square on the MFT with the thicker side of the square against the Guide Rail and the thinner side against the MFT fence.  I make whatever adjustments are needed until full contact of both sides of the reference square with the MFT fence and Guide Rail are achieved.  I confirm this by slowly sliding the reference square into the inside corner defined by the MFT fence and Guide Rail after the MFT components are "locked" in position.  Occasionally I find I have to readjust the stops in the Side Rails of the MFT, and the Festool clamp at the far end of the fence that clamps the far end of the fence to the side rail of the MFT.  I frequently find myself completely removing all of the fence hardware from my MFT including these stops in the side rails, and I don't find it takes much time to reset.  You can make marks on or within the channels of the side rails to facilitate recreating a previous setup position of the Fence and Guide Rail if you desire, but it is not necessary.   When delivered, the stops on my MFT 1080 were not correctly preset for the Guide Rail so I got used to setting them right at the start of my Festool experience.

For the components to be crosscut whose cut length was within the range of the MFT fence, I used the Festool Adjustable Stop (Item #49055) supplied with the complete MFT 1080.  For components whose length exceeded that of the MFT fence, I used one of the two setups shown in the following photos.  One setup was a scrap wood block clamped to the top of the extra MFT 800 positioned to the left of the saw as shown in the photo below.  This is not my preferred setup.  If this setup is used, be sure to clamp the block down with a pair of clamps, using only one clamp may result in the  stop block moving when the stock to be crosscut is slid into position.  The mass of a large panel of plywood bumping even rather gently against a Stop Block held with a single clamp is enough to make it move, and thus a potential source of cumulative errors.  I learned this the hard way after cross-cutting some of the plywood panels.  Then I added the second clamp and had to recut the panels to a slightly shorter standard length, so my drawings and my actual construction are not exactly identical.



Here's another view of the Wooden Block as a Stop with a pair of Festool clamps holding to the MFT top.




The other setup, which I prefer for crosscutting long wide stock, utilizes a Squaring Arm (a concept from Jerry Work's MFT manual) extending across the extra MFT 800 and secured to its side rails, as shown in the photo below.  After trying this idea, I preferred it because of the rock solid support that it provides all along the base of the (wide) stock to be crosscut.  The reference square placed with one leg against the MFT fence and the other against the Squaring Arm can be used to make this a precision right angle setup as well as a cross-cut stop.  Because the lengthwise edges of my Squaring Arms are rounded over (one fourth inch radius), a little sawdust trapped under the reference edge of the stop against which the stock to be crosscut was abutted did not interfere with getting accurate, repeatable contact with the Stop as might occur with use of a scrap of wood for a stop as in the first setup.  Use of the Squaring Arm as a repeat crosscut stop also freed up a pair of F-style clamps, and was very stable.  Sliding a large ripped panel firmly against this stop did not change the setting of the Squaring Arm as a stop.  Note that the Squaring Arm stop can also be clamped midspan to the top of the MFT to further secure its position setting. 



Here's closer view of the Squaring Arm used stop for repeat crosscuts to exact length:



The little strip of 1/4 inch thick oak positioned under the panel on the MFT 800 is to compensate for the use of a sheet of 1/4 inch plywood on the MFT 1080.  I made several pieces of this 1/4 oak stock initially expecting to use them as trim around the bases of the cases of the entertainment center, but the customer (my wife) did not want that aesthetic feature.  Nevertheless, they came in very handy as shim stock for many of the tasks needed to construct this furniture because their thickness corresponded to the amount of offset between the side panels of the four cases I built and the front and rear edging as viewed from the sides,

Cross-cutting Long Pieces of Ripped Stock on the MFT in a Small Shop.

To set the Stop to the cross cut length desired, I used an ordinary retractable steel tape measure (Stanley brand) and placed a pencil mark at the desired length.  As a precaution, especially when cutting plywood panels, to length, I first checked the end that was about to be positioned against the stop for squareness and a good (smooth) cut end.  The factory cut end of some of the plywood I was using was good enough that I could use the factory cut end.  And the gross dimensions of the full sheets were about 48 1/5 inches by 96 1/2 inches, which enabled ripping 4 full lengths of 12 inches width from each sheet.  (This was not true of the lower cost birch veneer plywood I purchased a year ago from HD, which came from China.)  If the factory cut end was not square or was too rough or the end of a board was checked, I marked across the "bad" end then measured out a length slightly beyond the needed final length.

For shorter components, all I had to do was flip the Festool Adjustable Stop up out of the way, cut the stock a little longer than final length, flip the stock to be cut end for end keeping the same edge against the fence and against the lowered stop, and make the second cut to final length.

For components longer than the length of the MFT fence, after marking the stock to a length slightly longer than the desired final length, I lifted the factory or other "bad" end over the Shopmade Stop and crosscut the piece slightly longer than needed, then flipped the stock end for end keeping the same reference edge against the fence, and pushed the previously cut end against my Stop, and made the final cut.  This was possible with longer components because they could easily be flexed enough to hold them square against the MFT fence and down against the top of the MFT.  This avoided the need to first make a square crosscut on every piece of long stock, then flpping each piece of long stock (some more than 12 ft long) end for end in my small shop, then setting the Stop and making the final cut.  My method meant the maximum stock length I had to flip end for end was a little less than 7 ft long.  I did this because much of my garage/shop has only an 8 ft high ceiling, and this coupled with the Boom Arm on my CT 22 makes it a challenge to flip long boards end for end without opening the garage door and taking the boards outside to flip them.  (I was also very thankful at this time that I paid extra to have the center section of the garage roof done with a "cathedral" ceiling to gain a little more height.) 

More to come.

This morning, after first shoveling the (about 15 cm) of snow from my sidewalks, driveway, and deck, I settled down with my tea, toast, and marmalade to read the latest account of your project.  It was most enjoyable -much better than reading the newspaper with breakfast.

I like the way that you are, not only telling us about building the unit, but you are describing your techniques for using your Festool (and other) equipment.  You are providing some good advice and some great tips.

And, like Nick, I quite like the Kapex substitute!

I agree and am enjoying your read with my tea this morning.
I don't want to interrupt your flow but when you are done, and have the time, could you describe the fitting you used on the out flow end of your dust deputy.
Thanks,
Roger

Frank, you 're really English with a funny accent aren't you? First the fish and chips and beer and now tea, toast and marmalade.-I'm on to you!

Well, the Pellows came to Canada from Corwall in the 1820s, so I guess the I'm kind of English.

Oh yes, I also lived and worked in England for 4 years in the 1970s.

Dave,

This is really great.  I'm in the process of designing my own entertainment center and will be using many of the same tools for construction, so your detail in how you're using the equipment is especially appreciated.

I'm curious about what you did for cable and power management?  I notice in your picture that you have an outlet behind the unit to the left and lighting above.  Did you install a strip anywhere and, if so, did you include channels to run the wires?  It may be too late now, but a few of the back of the unit would be great as well.

Congrats on a great project!

Roger,

The outflow of the Dust Deputy (DD) is at its top.  The gray colored fitting adapter is made of somewhat flexible plastic and was purchased from Oneida at the same time I bought the Dust Deputy.  It upsizes the metal outlet of the DD to fit into standard 2 1/2 inch shop vac hose.  On top of that gray adapter is one of Festool's hose Connector Sleeves (Item #493047) into which is fitted the short (? one and 1/2 meters?) 50mm hose that comes with the Boom Arm (Item 492753).  The black rubber coupling is a 2 inch to 1 1/2 inch copper to PVC plumbing adapter made by American Valve, and is a standard item available at HD and Lowe's.  It costs ~$3 to $4 (I don't remember exactly) and comes complete with the stainless steel clamps.  To ensure electrical continuity to the CT 22, I used a short length of braided copper wire.  One end of that wire runs between the gray fitting at the top of the DD and is folded over the ID of that fitting, and thus wedged between the gray fitting and the Festool Hose Connector Sleeve which is made of Anti-static plastic, as are both of the Festool hoses used in my setup.  The other end of the copper wire extends from the gray fitting extends underneath both of the stainless steel clamps of the black fitting and that end of the wire is folded over the inlet end of the black fitting and thus wedged between the black fitting and the inlet hose coupling.  I have had no static accumulation problems with this arrangement.  The light colored tape that you see on the gray fitting simply holds the wire in place when I remove the connector sleeve and 50mm hose to dump the DD.  Since installing the DD, I have not had to change the bag in my CT 22 or clear the HEPA filters.  But I am a hobbyist and don't use this equipment to suck up drywall, cement board or masonry dust.

Greg, I had planned to write more on that later, but here's some information you might be able to use.  Notice the ~3 inch high "toe kick" at the base?  If you could see a back elevational view, or a bottom view of the Console, you would see a network of ~1" x 3" boards forming a subbase and adding rigidity.  But there is not a continuous board extending across the rear like you see on the front.  Instead, in plan view, there is a U-shaped recess into which can be fitted the surge protector power strip.  The depth dimensions of the interior vertical panels and shelves of the Console are 1 inch less than the depth dimension of the sides, and I made some deeper cutouts at the rear edges of the fixed shelves on the left and right to provide space for cables.  Although hidden by the TV, the cabinet surrounding it that sits on the Console has a single board at its base that extends across to join the sides of the upper cabinet.  The bottom edge of that board has a large cutaway area near the center of it span so the cables can be fed over the top of the Consol and beneath the base of the upper cabinet that sits on the Console.

Chapter III -- Entertainment Center

Playing with Dominos, aka making a lot of holes in my boards.

After cutting the components to width and length, I marked them using a graphite pencil where I would later want to remove the marks, and sometimes used a permanent marker on ends and edges that would not be seen upon assembly or installation, and began to machine the many mortices using my Domino machine.  (A gray Eberhard Faber Artgum eraser works great for removing graphite pencil marks, much better than pink rubber erasers.)  I didn't keep count of the number of dominos used in the Console but I did for the TV Cabinet that sits on top of the Console in which there are 100 5mm dominos.  For some of the mortices, I used the base of the Domino machine as my reference while at other times I used the fence.  Likewise, for some operations I used the bottom surface of the workpiece as a reference while at other times I used the top surface.  Frequently, I used the 1/4 inch thick oak boards I had prepared as shims to support the workpiece or the Domino.

The order of construction of the Console is as follows.  The photo immediately below of the mostly complete Console may help a reader to follow my description.



The side panels are permanently joined to the base panel and to the short shelves on the left and right with glued 5 mm dominos.  In like manner, the vertical partitions that support the adjustable / removable shelves in the center are joined to the short permanent shelves with dominos.  The vertical partitions are joined to the base panel with screws, although I did make a few domino holes before I changed my approach which you can see in the foreground of the following photo.



First, I first marked the plywood panels that would make up the sides, and cut the two rows of mortices into the inside faces of each side panel.  To ensure placement of the mortices at the desired elevation and front-to-back edge registry, I made a template using a scrap of plywood.  On both side faces of that template I marked lines identifying the reference edge of the template to be lined up with the reference edge of the side panels, e.g. the "front edge", and lines corresponding to the centerline (widthwise) of the domino mortices to be cut.  Using my large precision carpenter's square, I drew lines across the side panels that I used to position the template I had made.  With the template clamped in place over the panel on the MFT, accurately locating and cutting the mortices so all the pieces would join together as intended was relatively simple.  Here is a photo of the template in use to cut the mortices in the side panels.  In this photo, the mortices are being cut for the base panel.  Note the orientation of the Domino machine, its base is being used as a reference against the template.  Actually this is not the true template, it is on the right in this photo and the next two photos.



Because the base panel is made of 3/4 inch thick plywood, the mortices to be made in the ends of the plywood base panel using this technique will not be located at the centerline of the thickness of the plywood, they will be slightly above the centerline of the plywood.  To correctly match the mortices to be made in the base panel, the Domino base and bottom side of the base panel have to be used as the reference surfaces.  If these reference surfaces are not kept straight as the work proceeds, the base panel is going to be at a different elevation than intended (in this case higher) and the mortices to join the shelves and partitions are not going to match as intended. This is because I did not take care to ensure that the spacing within a row of the mortices was equidistant from the front edge and back edge and one another.  There is no need to make them so.   Worse yet would be to use different reference surfaces for the left side and the right side components of the Console, unless perhaps you're trying to make a modern art statement.

Here is a photo showing the orientation of the Domino machine to cut the upper row of mortices in a side panel.  The piece of 1/2 inch plywood is the actual template I used.  These mortices will be used to join one of the two short permanent shelves to a side panel.  (I apologize for the text box within the photo incorrectly stating this is a partition panel.)  Note that the reference surfaces are now reversed, and that fact must be kept in mind when cutting the mortices in the corresponding short shelves.



Lastly, here are two photos in which I have inserted my "Check Block" which is nothing more than a short piece of scrap plywood into the edge of which I have cut a domino mortice.  The check block is marked to indicate which would be the best face veneer of the plywood.  Note this check block can also be used to help ensure correct placement of the template and relative orientation of the Domino machine and panels prior to cutting any of the mortices.  You can also barely "kiss cut" a mortise to a shallow depth, remove the Domino and use the check block to confirm the mortice is where you want it before machining the mortice to its full depth.

Here is a photo of my Check Block in use confirming correct elevation of mortices.  Note the absence of any gap between the Check Block and the plywood strip clamped across the workpiece.


When the Check Block was reversed face for face, there exists a small gap between the face of the Check Block and the top edge of the scrap of plywood that is clamped across the side panel.  This is what would happen if the plywood cross panel to be joined to this workpiece is reversed (flipped) face for face.

Chapter II continued

The mortices in the edges of the base panel and the short shelves were cut with the shelves clamped flat against the top of my MFT, with the base of the Domino referenced against the MFT top.  When morticing the ends of the base panel, the BOTTOM surface of the panel was placed in contact with the MFT top.  When morticing ends of the short shelves, the TOP surface of each shelf panel was placed in contact with the MFT top.  Because no other components are located immediately above or below these short shelves, the shelf pieces could have been flipped end for end upon installation and still fit perfectly horizontal, but the elevation would be slightly different and the chosen (better appearance) veneer face might not end up where it is desired.  For that reason, I also marked each panel so I could identify each face and edge, and whether it was to become part of the left or right side of the Console.  I put the better veneer face up on these short shelves, so that required the better face be placed down against the MFT top when cutting mortices.

I used the same template used to locate the mortices in the side edges of the bottom panel and short fixed shelf panels.  At first I used the template like a story stick to mark the centerline location of each mortice in the ends of the bottom panel and short shelves.  I lined up the reference line at the side edge of the template with the front edge of the panel and then used the lines on it to mark on the panel whose edge was to be morticed.  Then I removed the template and drew a series of lines on the face of the panel using a small square, and used those lines to line up my Domino for each mortice.

Then I realized that that additional marking using the template was not necessary.  All I had to do was place the panel with the correct face down against the MFT top, then position the template on top of the panel and lined up with the side edge of the panel and the front edge of the panel chosen as a reference, clamp down the template to the MFT and cut the mortices.

Use of Domino machine to cut mortises for application of solid wood edging strips to 3/4 inch plywood panels.

The front and back edges of the side panels have solid oak strips attached with glued 5mm dominos.  The front edge strip is 1 inch thick and 1 1/4 inches wide, and joined to the panel so that the edging overhangs both faces of the side panels by 1/4 inch.  I marked the top and bottom ends of the strips and the panels and their faces and also numbered them so I would know later which pieces should be joined and in what orientation.  I did not use the registering dowel pins or the Cross Stop (Item #493488).  I have had some problems in the past when using these with (Chinese) plywood due to some debris hanging within a previously cut mortice interfering with registry of the dowel pin.  At about US$85 per 4 ft x 8 ft x 3/4 inch sheet, I did not want to ruin any of that plain-sliced oak veneered plywood.  In my prior use of the dowel pins to register successive mortices along the workpiece, I found that I had to peer under the Domino after cutting a mortice to ensure that the dowel pin was fully engaged against the end of the mortice I had just made and not catching on some "chaff"; that seemed more work and risk of problems than I wanted to risk.  So, instead I used pencil marks and visually aligned the Domino machine for each mortice. 

To faciliate marking the mortice locations for adding edging to the panels, I placed the panel with the edge piece to be joined to it on the panel and lined up so their exposed edges were flush.  While holding them in this position, I drew a series of lines along their exposed long edges corresponding to the locations of the dominos, placing one about 2 inches from each end of the strip, and about every 6 inches therebetween.  I also marked one end to be the reference, so I could cut the first mortice nearest this end of the associated pair of workpieces was cut with the Domino on its narrowest setting.  For the remainder of the mortices, I either used a wider setting, or plunged using the narrowest setting, then moved the Domino slightly to a side of the centerline and plunged again.  By making the first plunge slightly to the left of the centerline and the second plunge slightly to the right of the centerline, you can quickly make a series of mortices that are just a little wider than the dominos yet narrower than the middle setting on the Domino machine.  I don't like having any more void area within my projects than is necessary to assemble them.  Then I used a small square to continue those marks onto the adjacent faces of the pieces to be morticed, so the marks would be visible when using the Domino machine.

There are at least three different techniques to mortice the edging and its associated panel to assure they line up as desired when assembled.  One is to reference off the bottom surfaces of the Domino and workpiece.  A second technique is to reference off the top surfaces of the workpieces and not worry about getting the mortices exactly in the middle of the thickness of the workpieces.  A third technique is similar to the second technique, but care is taken to set the height of the Domino fence so that the mortices are very near the midpoint of the thickness of the workpieces.

The first technique is shown in the photo immediately following.  Although the following photo depicts use of the Domino machine to mortice a rear edging strip for either the TV Cabinet or a Bookcase section of the Entertainment Center, the same technique was used to mortice the edging for the sides of the Console.  The setup shown in the photo will cause the front and rear edging strips to stand proud of the panel by the thickness (1/4 inch in this project construction) of the shim boards placed under the panel and base of the Domino.  If you look across upside surface of the panel (which will be the inside surface in the finished construction), you can see that the edging on the opposite (which is the front) edge of the panel stands proud of the panel.  The face of the panel that is up in the photo is the inside face and the back edge of the panel is in the foreground just behind the edging strip.  Both the Domino machine base and the panel behind the edging are being supported on strips of 1/4 inch wood, and what will become the outside-facing face of the edging is clamped down in contact with the MFT top as needed. 



I used the technique shown in the above photo for application of some of the edging strips, but I also used a seond Domino morticing technique in which the mortice elevation is referenced off the top surface of the workpiece to be morticed.  This second technique is much preferred when you want a surface of the edging to be flush with the panel to which the edging will be joined with dominos.  In this technique the fence of the Domino machine is set at 90 degrees and is pressed down onto the reference surface of the workpiece to be morticed.  If you go to the Gallery and enter "domino" in the search box, you will find among the "hits" a photo (IMG_7390.JPG) by Bill Wyko that shows a mortice being made using this technique into the edge of a sheet / panel he created.  Referring to my photo above, if the Domino machine is reset to have its fence at 90 degrees (so face of the fence which is its registration surface defines a plane parallel to the axis of the cutter) as shown in Bill's photo and is pressed down by the forward handle on the fence onto the surface defined by the top surfaces of both the edging strip to be morticed and the panel surface behind the strip, the inside surfaces of the edging strip and the panel will line up flush when the parts are joined.  Note how the top surface of the edge strip being morticed is flush with the surface of the panel.  This second technique is the one I most recommend for applying edging where the joined surfaces must be very near to flush and you don't want to have to use a flush trim router bit after joining them, and you don't dare risk sanding through the thin face veneer of the plywood.  For me, this technique produced elevation matched pieces that needed only some scraping and light sanding which did mostly with my ETS 125 and LS 130 using 120 grit and higher abrasives.  I made certain that none of the shim boards shown in my photo used in the first technique were positioned under the base of the Domino so it could not rest on them instead of registering only through the Domino fence.  When using this second or the third technique, either elevate the workpiece relative to the top of the MFT to provide clearance under the bottom of the Domino or positon the workpiece so it is cantilevered out beyond the edge of the MFT.

I also used a third technique in some of the construction.  If I wanted the mortices to be very near to the center of the thickness of both the plywood panels and the front edging strips, I found that, too, was not hard to do.  I also used this technique to cut mortices into the side edges and ends of the edging strips to form a face frame upon assembly of some of the front frame pieces of the Entertainment Center.  I did not get to this confidence level until construction of the TV Cabinet which I made last.  I measured the actual thickness my plywood using a digital caliper (available from Woodcraft and others for about US$40), then set the height of the fence of the Domino to one half the measured amount.  Perfect centering was not needed for this operation.  As I progressed through construction of this Entertainment Center and experimenting with use of the Domino machine, I realized that I could come very close to the center of the thickness of the plywood or wood edging strips by simply marking the centerline of the wood piece then eyeballing the location of the Domino pins as I adjusted the height of the Domino fence.  I also noticed on my Domino machine, when viewed at front quarter angle from either side, there is a highly visible horizontal mold partition line in the aluminum housing adjacent the bosses into which the dowel pins are fitted that appears to closely correspond to the centerline in elevation of the dowel pins.  I don't know if every Domino machine has these visible features, but I would expect them to.  Sometimes I used that flashing/parting line to make the fence height setting when I wanted to center the mortices relative to the thickness of the workpiece.  The dowel pins appear to be at the same elevation as the centerline of the Domino Cutter, so if the dowel pins and that mold parting line appear to be on the thickness centerline of the workpiece to be morticed, so will be the mortice.  I also found I could easily visually check the elevation setting of the Domino fence, especially in plywood because the veneer layers serve as a guide.  I drew a pencil line corresponding the the thickness centerline of the 1 inch edging strips and used this to confirm the height setting of the Domino fence.  I needed to do this several times while assembling the TV Cabinet with its fully dominoed frame.  Checking this visual technique against actual mortices and the thickness of the plywood and other components I was making indicated I could usually get within 1/2 mm of center of thickness with little trial and error.  That is close enough most of the time, but not if working with thin veneered plywood onto which you are trying to apply a flush edging strip.

Also, when morticing these edging strips, it is important to first position each strip relative to the panel to which it is to be joined in the oriientation you want the pieces to be when assembled, and to make your pencil marks for the mortices while in this orientation.  After marking the edging, flip it end for end keeping the same edge surface up, position it against its associated panel and cut the mortices.  Again, it is very helpful to mark each piece of edging and panel so you know which pieces go togeher when you're ready to glue-up.  I did not glue on the edging until I completed several stages of dry fit checks and drilled the shelf pin holes using my LR 32 Guide Rail and Hole Drilling Set (Item #583290) with my OF 1400.

For morticing the ends of the edging strips, which I did as I progressed through several dry fit checks, I used Festool's Trim Stop (Item #493487).  In contrast to my experience with the Cross Stop (Item #493488), I had no problems using the Cross Stop.  I found it very easy to install on the Domino and very easy to setup to center the mortice in my 1 inch thick by 1 1/4 inch wide front edging stock, and surprisingly accurate.  [Based on this experience, making some chairs may be in my future!]  The Cross Stop was not used in construction of the Console, but was used in construction of the Bookcases and TV Cabinet which rests on top of the Console.

Mortising the Edging for the Top of of Console

The main panel of the top of the Console is a piece of 3/4 inch veneered plywood.  It is surrounded by a mitred three-piece frame of oak stock 1 inch thick by ~2 inches wide.  The mitred frame is attached to the plywood panel with dominos.  As you can see in the photos of the finished console, the mitred frame and center panel are flush on the exposed top surface, but offset 1/4 inch when viewed from the underside.



Here's a view of a the underside of a front corner of the Console top.


This was my first attempt at using the Domino machine for applying mitred edging, and also my attempt at cutting the mitre joints.  Unlike a picture frame whose center is hollow, there is no room for error here.  All of the cut edges must be straight and clean and the elevations, lengths and angles must be exact.  My approach to these issues was to always reference the Domino off the top surfaces I wanted to be flush when joined, then to machine the mortices into the edges of the plywood panel and framing pieces to be joined.  I first cut the framing stock to have a couple of inches of extra length, so I could tweak the mitres if needed.   Then I cut a mitre on one of the short frame pieces and on one end of the front frame piece.  Sorry, Festool, I made the mitres on my table saw; I did not want to clear my MFTs to do them with Festool equipment, and I don't have a Kapex or other quality mitre saw.  After I was satisfied with the fit of the mitred pieces for one corner to one another and the front and one side edge of the top panel, with them in position relative to the panel I marked out the locations of the mortices using a pencil.  I did not cut the other mitred corners until I was satisfied with the fitment of the first corner pieces to themselves and the center panel.  I did not have any extra 4/4 stock from which to cut new framing pieces, so I proceeded cautiously, incrementally working toward the final goal.

The first photo below shows the mortises in one of the side framing members.  The mortices adjacent the mitre were intentionally made extra wide to enable the pieces to be rotated somewhat into final positon as they are slid together.  If the mortices are tight relative to the width of the dominos, the mitred pieces with their dominos cannot be assembled to both themselves and to the center panel.  Note also the double tenons in the mitre joint.  To position these mortices, I simply laid a pair of 5mm dominos on to of the mitred pieces while they rested on the MFT top, and made a pencil mark corresponding to the approximate centerline of each domino.  That visual technique also assured I would not cut through the mitred frame pieces provided I kept the Domino machine set to plunge 15mm, which I did.  Then I removed dominos and extended my pencil marks using a try square postitioned against the cut edges of the mitres.  Then I cut the mortises with the Domino machine.  I did several dry fit attempts and extended the width of the mortices as needed to enable the joints to be brought fully together and the domino tenons to be fully seated in their mortices.  I could see where the mortices needed to be widened as rotated the framing pieces into position, and made pencil marks to help guide my placement of the Domino machine to widen the mortices.  This was easy to do with the Domino machine, all I had to do was simply move the machine laterally from my centerline by the amount I wanted to widen the mortice.



Several dry fit checks were made; the mortices were widened as needed to enable full closure of the mitre joint and contact along the full lengths of the framing members and the center panel.



Here is the final dry fit.  The glueup looks the same.  All of the pieces came fully together.  The joints have remained fully closed since the finished Console was brought from my garage into my house a few months ago, despite the lower humidity in the house.



More to come.

WOW Dave, this morning there was more to read than I could get through in one breakfast.  I need to get to work, so I will save the unread material for tomorrow morning.

I don't have a Domino, but it is informative to learn how you are using yours.  I think that my Dowelmax could manage similar joints, but I am not certain.

I particularly enjoyed a chuckle over this sentence "Worse yet would be to use different reference surfaces for the left side and the right side components of the Console, unless perhaps you're trying to make a modern art statement."

Thanks, Frank.  Re the Domino machine, I could almost say "I love my Domino"; in my opinion it is that good.  One feature it lacks that I wish it had is the ability to simply drill upon plunging without the sideways oscillation.  Then it could also be used to quickly and accurately bore holes perpendicular to any work surface, or at whatever angle the user chooses.  It would then become essentially a miniaturized, portable, precise drill press while retaining all of its present, unique capabilities.   Many times I have needed to precisely bore through something that cannot be brought it or loaded onto a drill press table, and the best I could do was to make a hardwood drill bit guide block (bushing) on my drill press for use with a handheld drill at the primary workpiece.  If the Domino had the ability to simply bore a cylindrical hole, it could also be used with dowels.  A single dowel can be used as a rotary joint, a domino joint cannot.

Chapter III -- Entertainment Center Console continued

Drilling the Console Shelf Pin Holes

After cutting all the mortices on the panels, I used my LR 32 Guide Rail (Item #491621) together with my LR 32 Hole Drilling Set (Item #583290) and OF 1400 router fitted with a Whiteside brand ? inch solid carbide double-fluted straight bit to drill a pair of rows of shelf pin holes on the confronting faces of the vertical partition panels of the Console.



Because I did not need to adhere to the dimensional standards for the Euro hinge system, I held the panels together in elevational alignment and used my large precision carpenter's square to draw a lines across the inside faces of the panels where I wanted a row of shelf pin holes to begin.  Then with a pair of Festool's Edge Stops (Item #4857580 installed on the LR 32 Hole Drilling Guide Rail, I positioned the LR 32 Hole Drilling Guide Rail on the panel to be drilled with a hole of the LR 32 Guide Rail centered on my pencil line.  This simple technique allowed me to position (in elevation) the holes wherever I chose rather than being limited to the specific distance of a given hole in the LR  32 Guide Rail that will result from use of the Linear Stops that are supplied with the LR 32 Hole Drilling Set (Item #583290) and installed in the end of the LR 32 Guide Rail in use.  (See the tutorials of Brice Burrell or Overtime or Mirko for instuctions on use of the components of the LR 32 Hole Drilling Set (Item #583290) as Festool designed them to be used.)  Below is a series of three photos that illustrate the techniques I used to drill the holes in the Console panels and later in the bookcases.  In making the Bookcases, the rows of shelf pin holes were much longer than in the panels and I had to "walk" my 42 1/2 inch long LR 32 Guide Rail lengthwise to continue a single row of holes.

Note particularly the pencil line.

You might think by now that I was ready to begin assembling the Console.  You'd be partially correct, but not completely.  I glued the front and rear edging onto the side panels, the front edges of the partitions.  For the adjustable shelves, I added 1 inch thick edging to one long edge and 1 inch thick edging to the other, thus enabling the adjustable shelves in the center comparment of the Console to be installed in either orientation to give a different appearance as shown in the following two photos.

Console shelves with 3/4 inch thick edging in front (corresponding to the thickness of the plywood panel of the shelf).

But those photo are getting ahead of the chronological order in which I built the Console.  Due to several small interior spaces, I decided to try prefinishing the components of the Console before final glue-up assembly.  But before that I did another dry fit check.  It is difficult to see them in the photos, but I made four gauge blocks from scraps of wood to the length corresponding to the width of the narrow permanent shelves (one on the left and the other on the right in the photo below) and set them on top of the base panel to ensure that the vertical partitions would be correctly located.   Look in the lower left of the following photo for the piece of blue tape which is on one of the four gauge blocks.

With them in place, I installed 2 inch long Spax screws into the partitions from the bottom and used these for subsequent dry fit checks and for final assembly.  These screws are premium priced, but they can be used as self-drilling screws in wood and similar materials, and with a pilot hole, even into concrete.  (I used pilot holes to mitigate any risk of splitting the wood which I think is more of concern when the screws are being driven parallel to the faces of plywood.)  Their heads are very precisely formed and a Number 2 Posi-Drive bit fits perfectly unlike the sloppy engagement and resulting camout that often occurs with Phillips head and even square drive (Rorbertson) screws of lesser quality.   About this time I thought I was going to run out of clamps, so many were required for the dry fit checks as more Console components were added.  (I turned this into an opportunity out of it by having my wife come to see the my progress and showed her why a woodworker can never have too many clamps!  She had previously questioned why I would ever need as many clamps as I own.)



While the Console was assembled for a dry fit check, I fit the front edging that would later be glued and secured with dominos, and also the front toe-kick board (not shown in the photo above).  If you look carefully just under the top you will see a board extending from the left side panel to the right side panel.  That board and another like it were let into notches I cut into the vertical partitions and fastened to both side panels and both partitions with screws.  The kick-board was also drilled for installation of pocket hole screws.  To make the pocket holes, I used a Kreg jig fitted with my shopmade dust collection hose adapter. I made the adapter from a section cut from a Carlton brand PVC electrical conduit 90 degree bend, 1 1/4 inch diameter, I think.  Festool's 27mm tool end hose fitting (Item #487071) is too large to fit into the blue-colored dust collector supplied with the Kreg jig, and Festool's 36mm hose fitting (Item #487721) is too large to grip the outside of the Kreg collector nipple.  Below is a photo of my adapter in use.  If you decide to make an adapter like this, note that you will have to slightly enlarge the end that fits onto the Kreg dust collector shroud by grinding away a little of the plastic.  I used a small sanding drum mounted in my drill to do this.  The wall thickness of this conduit is quite thick (Schedule 80).  You can remove the tool end fitting from your Festool 27mm hose and take it with you to HD or Lowe's to ensure you get the right size of conduit, and you just might something that fits even better without need to grind.  Use of a curved hose adapter reduces the stress on the mounting of the Kreg shroud which is fairly easy to to pop loose.  When the Kreg jig with shroud is used with a CT 22 at full power, nearly all of the drilling chips are captured at the source.  This jig could be mistaken as a Festool if it wasn't some furrin' Farbe blau.   Removal of the chips as they are created also reduces stress on the special drill bit used with the pocket hole jig and enables drilling the holes with a faster feed rate.  The more I use the Kreg jig, the more I like it for assembly of components where the pocket screw holes will be hidden from view.  I used the Kreg jg later to drill pocket holes on the top and bottom panels of the Bookcases and TV Cabinet; these helped draw the domino joints together.



I made the door frames from 5/4 oak stock (true 1 inch thick).  The pieces were cut to exact length with square ends on the MFT using the flip stop supplied with the MFT 1080, and the butt joints were morticed with the Domino machine for a single 10x24x50mm domino at each joint.  After glue up, I clamped the door frames to the top of my MFT using Clamping Elements (Item #488040 and / or F-style Quick Clamps (Item #491594) and sanded them flat using my RO 125 followed by my ETS 125 on top of my MFT.  After assembly of the door frames, I made another dry fit check, this time with the edging installed.on the base panel.  In one of the near final dry fit checks I installed the hinges to help ensure proper clearances before applying any finish coats.  On the backside of the doors, I routed a rabbet using a bottom bearing bit and hand chiseled the corners to accept later installation of the decorative glass panels, and ordered the glass.  The glass was not installed until after completely finished.

Sorry, but I could not find a photo of the door frames showing the back side.

After I finished drilling the shelf pin holes, and was satisfied with the dry fit check, I began to assemble the Console components with glue.  I glued the front and rear edging strips onto the sides and other plywood panels and shelving.  Then where needed I scraped and then sanded the edging and panel surfaces flush, using mostly my ETS 125 and LS 130 sanders.  For most of this work I preferred the fine degree of control provided by the LS 130's linear motion, which is much like hand sanding except much faster, and with less airborne dust.  The LS 130 is certainly not an aggressive sander compared to others in Festool's product line, but if you want to remove material a little more aggressively all you have to do is hold the sander so its back and forth motion is at an angle to the grain direction.  Then return to sanding with the grain to remove those cross-grain scratches.  Not once did I cut through the very thin oak veneer of the plywood.  I was concerned about this as I had never before built a furniture project using veneered plywood panels for the main surfaces; I was a traditionalist who glued up the needed panels of solid wood boards.  An additional advantage of the LS 130 for this task is that it eliminates the risk of creating deep sanding scratches across the grain the remnants of which only show up when you apply a pigmented stain.  I learned this the hard way even after sanding with my ETS 125 through 220 grit, and had to scramble to wet sand out such scratches while staining some of the components of this Entertainment Center.  That was a lot of extra work and a waste of sandpaper I would rather avoid in the future; besides, the very thin veneer can be easily cut through when trying to remove scratches created by a rotary or orbital sanding machine by further use of a rotary machine with fine abrasives.

I glued the short shelves to their respective partitions before gluing these sub-assemblies to the rest of the Console.  As can be seen in the photo below, the MFT proved very useful for this task because I could draw the glued domino joints together by tightening the bar clamps the bottom jaws of which engaged the bottom edge of the side rails.  [Remember that I am working alone and don't an extra pair of hands to help with these tasks.]  Even though I sanded the 5mm dominos and chamfered their ends, a lot of force was required to seat them fully close the joints between the components being joined.  Most of my construction used original dominos sold under Item #493296.  Despite spending a lot of time sanding there faces and edges, they were still a very tight fit.  Festool has changed the dimensional specifications for their 5mm dominos; the reduced size ones are sold undere Item #494938 and are significantly easier to put into a domino mortice.  But I did not have any of the new Item number until I was nearly finished with this entire Entertainment Center.  I found this out when I needed more 5mm dominos to complete this Entertainment Center.  This domino fitment problem seems to be limited to the 5mm dominos; the 10mm dominos were a "tight slip fit" during dry fit check and the joints not difficult to draw together with clamps or a mallet when gluing up the door frames.


The cutout region with the curved ends in the vertical panel in the above photograph will become the right side fixed shelf when this sub-assembly is joined to the side and bottom members of the Console.   The cutout region on the back edge of the short shelves of the Console can be used to route electrical cables, if needed, to equipment on the shelf.  When I started designing this Console, the cable decoder box was small enough to fit easily on this shelf, but the DVR they replaced it with cannot.

After completion of these sub-assemblies, and final sanding, I applied stain and finish coatings to them, prior to final assembly of the Console.  There were so many components that I cannot show them all in a single photo.  They were strewn all over my shop to dry between applications of additional coatings.  If you continue reading through my story, you'll learn how I changed my order of work when making the Bookcases and again when I made the TV Cabinet that rests on top of the Console.



More to come.

Chapter IV - Finish Schedule and Notes.

Finish System, Problems and Solutions

The finish schedule I followed for nearly all components of this Entertainment Center is listed below together with some notes based on what I learned making this Entertainment Center.  The finish system I used is a combination of solvent based and water based coating materials, applied using a combination of brushing, wiping and spraying.

1.Sand through 220 grit.  I used Festool sanders and Festool Brilliant abrasives for 180 and 220 grit, for lower grit numbers I used Rubin interchangeably with Brilliant.
2.Vacuum all surfaces to be finished using the brush attachment on the shop vacuum.  I also vacuumed every surface I could reach in my garage / shop to reduce creation of airborne dust during later spray applications of coatings.  If possible, I recommend applying the finishes in a different room than was used for machining and sanding the pieces to be finished.  I did not have that option, although for some of the finish applications on some components of the Entertainment Center the weather permitted me to apply the spray coatings outside.  That has its own set of associated problems, in my setting including rain, very high humidity, insects landing in the wet finish coat, and due to my lot having many large trees that border my driveway, leaves and pine needles landing in the wet finish coat.
3.Wipe all surfaces to be finished with a clean, dry microfiber cloth.  I used the same gold-colored cloths I had purchased from Griot's Garage a few years ago for use when hand polishing my cars.  They are reusable indefinitely provided you properly wash them to remove accumulated dirt and dust.  There are differences in quality among brands of microfiber cloths and different fiber types, diameters, lengths and numbers of fibers per unit area.  Do not use fabric softeners when laundering them.
4.Apply wash coat of 1 lb cut alcohol base shellac.  I used Zinnser's Seal Coat and diluted it with denatured alcohol.  This was applied with a brush.
5.Apply oil-based stain.  I used General Finishes wiping stain, Pecan color.  This product is very slow drying even under ideal conditions of low humidity and temperatures around 75 degrees Fahrenheit.  For the Console, I applied a second coat of the same stain a couple of days after the first.  There did not seem to be much effect on the depth of color, although it did turn out slightly darker in appearance in some lighting conditions than some of the Bookcase components on which only a single coat of stain was applied.
6. Apply wash coat of alcohol base shellac.  I used the same 1 lb cut Seal Coat as above.  This is where I ran into a major problem.  Do not brush this coat.   As I brushed on the shellac, the solvent apparently began to attack the binder used in the oil-base stain, and the stain started to smear with my brush strokes, being removed in some areas and deposited overly thick and dark in others.  Eventually, after some quick removal of the excess, and some quick restaining / touching up of the lighter areas and blending efforts, I repaired much of the blotchiness.  If you look carefully in the below photo which shows the top surface of the bottom panel, you will see what remained of the problem.
Insert Photo 089.
I entirely avoided this problem with the stain by spraying a light mist coat followed by a slightly wetter coat of the 1 lb cut Seal Coat when finishing the rest of the this Entertainment Center.
7.Apply wet coat of Target Coatings' Oxford Brand Amber color water based shellac.  No dilution was used.   I simply poured it through a paint strainer into the cup of my Fuji HVLP spray gun.
8.After the water based shellac is dry, inspect the surface.  Respray with water based shellac if coating appears rough or insufficient.  If the first spray coat felt roughtor appeared to entrapped sanding dust or raised wood fibers, I lightly sanded the coating with 320 grit wet or dry  (black silicon carbide) sandpaper to knock down these high spots.
9.If you sanded the shellac coating, wipe it down with a microfiber cloth.
10.Apply wet coat of Target Coatings Oxford brand vinyl sanding sealer.   This material was rather viscous as packaged by the manufacturer.  Generally I slightly diluted it using distilled water, or water collected by my basement dehumidifier.  Tap water is likely to contain minerals and chemicals which may chemically interact with Oxford's water based products.  The main reason for diluting this sealer is to help avoid the coating bridging over the pores of the red oak.  I wanted to partially fill them with the finishing coats.  I did not want them fully filled since other commercially manufactured oak furniture in my house does not have fully filled pores.  Let the coatin fully dry. Under good conditions of moderate temperatures and 50 ? 60% humidity will likely only take about one hour.
11.Inspect the dried coating and recoat if you think it necessary.  Again, you are looking for spot with defects compared to the areas immediately surrounding them.
12.After the sanding sealer coats have fully dried and hardened (I allowed at least a couple of hours), sand the surfaces with 320 or 400 grit wet / dry abrasive.  How far this coating is knocked down by sanding will significantly influence how much the pores appear to be filled in the final finish.  The more this seal coat is knocked down, the smoother and less open porous the final finish will be.
13.Wipe with microfiber cloths.
14.Apply wet coat of Oxford brand water based gloss lacquer and let dry.  Apply another wet coat if desired.  Whether or not this is advisable is dependent on many factors, a very important one of which is spray gun operator technique.  I have found that I can set a spray gun so that I get a good even but thin wet coat, then hand that gun to another person who will have problems achieving the same result due to holding the gun at a different distance from the surface being sprayed, holding the gun at a different angle or moving the gun at a faster or slower speed.  I recommend experimenting on the underside surfaces of a workpiece or some cardboard or a sheet of paper to get a feel for how operator technique and spray gun settings influence the result. 
15.Inspect finish. Knock down any dust bumps with 400 grit wet or dry sandpaper if the surface bumps can be felt with your bare hands.
16.Wipe with microfiber cloth.
17.Apply wet coat of Oxford brand water based semi-gloss lacquer.  Let dry.  Inspect finish.  If clean and smooth, proceed to next step.
18.Apply second wet coat of Oxford brand water based semi-gloss lacquer.  Let dry.  Inspect finish.  If smooth and free of defects., you are done.
19.Let the finish continue to dry and harden.  Several days are required before the finish fully dries and cures and reaches its full hardness and resistance to physical (abrasion) and chemical substances (spills).
20.Take a well-deserved rest and  Admire your hard work!
 
Notes regarding the above listed finishing schedule and materials.

A.  Red oak often contains significant amounts of tannins (tannic acid).  Many of Target Coatings water based products are highly alkaline, and potentially reactive with the tannic acid in the oak.  For this reason, Target Coatings website recommends using oil-based stain and sealing that stain with solvent base dewaxed shellac (which Seal Coat is) followed by a coating of Target Coatings water based shellac which they consider to be a universal sealer compatible with all of their other coating materials.

B.  If you realize you have applied too much finish, you can simply wipe it away with a dry cloth or even a paper towel, with any of these water based coatings.  A run on a vertical surface is obviously too much finish in a single coating.  So is an area in which the coating appears overly thick as evidenced by a thick wet, shiny layer that is milky in appearance.  After wiping the excess away, let the remaining finish dry, and later recoat.  This is an advantage of Target's water based coatings that does not exist with solvent based lacquers I have used in the past.

Next installment - building the Bookcases.

Dave: This is a great thread. Thank you very much for posting in such detail. As a new owner to Festool, everything I see sure helps me understand how to use the system. Pictures are so much easier to understand than 10,000 words.  Smiley

Thanks, Mark.  I bought my first Festool, an RO 125 about 3 years ago.  But I used a Shopsmith and other hand and power tools for many more years as a hobbyist and serious DIYer.  By serious, I mean projects like removing the main wooden beam of my house and replacing it with an iron beam to get rid of a centerpost, building a fireplace replacing most of the copper plumbing in my house, and cutting and threading the iron piping needed for installation of gas furnaces and fireplace gas lighter, installing foundation drains, making my own flooring starting with green lumber selected at the sawmill, harvesting and my own trees.  I don't mean to brag, I'm just stating some of my experiences gathered over 40 years.

Dave you are not bragging! This is a forum and talking about tool, woodworking and construction experience is the point, isn't it?

And so what if you did brag, you can back it up!

Nice thread.
