Has anyone used the multi function slab?
« Reply #30 on: June 02, 2017, 10:41 AM »
I think the trouble with multiplex birch would be that it just does not hold up well when used outdoors.
Weather/Sun/Humidity will take it's toll and as soon as the "top layer" starts going bad, you will regret going with it. I'd stick to moisture resistant MDF...

See "outdoor" suffered multiplex pic attached...

Edit: just to explain, this was covered with 3 coats of PU based clear coat, not untreated.

I have a cnc and made mine from 3/4 mdf.  I love it.

@ grobkuschelig - thanks for the warning. A pity. I love birch tree...

@Nick561 yours should be 19 Millimeter if I calculated correctly (3/4 inch). So clamps work without any problems? And - is it still stable enough? Finally - how much does it roughly weight? I originally come from Bavaraia - we would say more than a tray of beer bottles (20x 1/2 Liter, a little less than 20 Kilo)?

Last thing - I found so many different saw horses... I would like some stable ones so you could also use a rotex on it (so pressure not only going downwards but also sideways) - and recommended for this?

Today TSC 55 Li REB-Basic should come :-)

Greetings!

I know this is resurrecting a somewhat dead thread but will be moving forward with this as my first project with some Festool action.  Recently started to help my son with his house and realized that dust collection was one of the most challenging aspects of home DIY.

Jumped in with both feet for him and me...realized we needed something akin to the MFT/3 but was hesitant to spend the money right away.

Anyway have two sheets of 1" MDF coming...should have gotten 3/4" to work with the FT clamps but too late now.

BTW...so far quite pleasant to read the various threads with guidance, comments, reviews, and tales of woe.  Nice site!

If you chamfer the back of the holes with a roundover cutter the festool clamps will fit.

Thanks....first step is picking up the MDF on Saturday.  Apply some polyurethane to seal things up then drop off the pieces at the CNC shop.

I made one a year or more ago out of 3/4" MDF. It's 3' x 5'. I was growing tired of using foam pieces when cutting with the track saw on my workbench.

Mine is more along the lines of Peter Parfitt's Track Saw Cutting Station as I only have some of the dog holes drilled, mainly the ones I use for the Parf dogs to align the track and material. I used the Parf Guide system when building it. All the 3mm holes are drilled so if I need more 20mm holes they can be easily added. It was made to be cut into and has kerfs cut in quite a few places. That's its sole purpose - a track saw cutting station.

The one feature about the MFS that I did not like was the handle placement. Two handholds on one edge seemed to me to be an awful design decision making it awkward to carry. I opted to place a single handhold in the center of the sheet which allows me to carry the slab under my arm. I don't move it very far other than from its storage location onto the sawhorses, but if I were a contractor carting this thing around that's definitely a better location for a handhold.

I use foldable plastic sawhorses available at Lowe's. Seems to do the trick and I've used my router and sanders on this. It's stable enough but nowhere near that of a dedicated workbench. When I need it, I can set it up in under 2 minutes.

The one issue I've had with it is warping. I had it set up on the sawhorses at one time for a number of months. I wasn't expecting 3/4" MDF to warp, but it did. I may fix it at some point by routing a sliding dovetail into its length and using a piece of hardwood to try and stiffen it.

Thanks Lunchman.....good feedback on the carrying slots...laptop shoulder strap might be a good choice with the original slots.

I have made a few MFT slabs using the PARF GUIDE SYSTEM. I had 3 sheets of 4 x 10 MDF, so I cut the first one in half and made my own design for the holes, clamp slots etc., then commenced to the drilling. I found the first one to be an excellent size which allowed me to work on cabinets, cabinet sides, face frames, big glue-ups. 4x5 tops seem to work for me.

Most of the time I'm working in a conditioned area so the humidity is low. Nevertheless, I do notice sag when I used the plastic horses. It helps to use the 2 x4's in the slot provided in these horses. Having the 2 x 4 support also gives you a way to temporarily clamp your top down. Just pick 2 really straight ones. Good luck. [emoji38]I use two Bessey clamps and it makes the setup pretty solid.

I'm thinking that the next batch of tops I do will have the handhold in the middle, that's a great idea. I might even urethane the tops.

At this time I'm using the several pair Store Horse metal horses, of which I have now purchased every grade they make. Be aware that the lower number grades hold less weight and do not have adjustable height. I've bought them at home depot and online, when a deal came up.

BTW I use Harbor Freight movers quilts to put over my mdf tops to make a nice soft, scratch free zone for finishing parts and such. It's proven to be a great work area for my intermediate sanding between coats of finish. Just don't try to wash the quilts, they'll just fall apart, and they will deform horribly in the dryer [emoji33] I got several sizes, about 15 of them for 100 bucks.

I have been apply the poly to my two sheets and have definitely noticed the need to support the sheets on the sawhorses with 2 by 4s....so far I am not sure I will actually be able to have the sheets CNCed.

Running into cost issues so far...waiting on a shop to give me a quote...at least they called me to discuss the job and ask questions.  If it ends up being too expensive I will take the UJK route.  Will take longer but I have also started to look at the MFS slab drawing with changes I would like, particularly the handhold in the middle.

While spending time making your own MFT top using the UJK Parf guide, you develop a relationship with the piece. You customize it to your own needs and it becomes more then just a slab  [big grin]

I have one of the UK made Custom Solutions slabs.
Its made from 3/4" MDF, has lots of holes, easy enough for any able bodied person to lift and carry about and accurate.

Err, it was cheap enough and I generally just put it on a couple of bits of 2x2 across two sawstools.

1" MDF is too heavy making it difficult to move.

@clark_fork what size is your MFS?  I was going to have one cnc'd but if it's too heavy at the size it was designed I may have to rethink that.

 3' x 5" X 1"

Perhaps the 3/4" would be more manageable but the 1" is unmanageable even with the splendid hand hole system.

The one inch thickness has an even worse complication. Clamps can't be seated in the hole and each hole has to be routed from the bottom to soften the hole enough to accept the clamp.

There is nothing wrong with using thinner stock and adding under battens if need be.

Overall, this has been a very good design with the hand holes, hose placement slot and clamp slots. However, I later bought the MFT/3 for cutting and now use this slab mostly for assembly work, squaring, clamping and with a sacrificial top for finishing.

I made 1" thick Baltic Birch plywood versions in 2 sizes. Easy to move and rugged as heck. Tongue oil finish. All clamps work in the holes with slight chamfer or roundover.

Here is where I get my wood and ply, the 18mm 30" x 60" is 28CAD$ zero void.

Of course you will have to travel a bit  [tongue]

I agree with clark_fork..1 inch MDF is a bit of challenge to move.  Picked up my four pieces from the CNC shop and the tops are pretty heavy.  Overall the shop did a nice job for a very fair price.

I'm considering using a MF Slab as the top of my outfeed table...what's the ballpark cost to have a CNC shop do the work? I've also found a local guy selling these for $150, but not sure if it'd be cheaper to buy the CAD file and have it made by someone else?

Depends on many factors. First to reduce the cost you have to come with your own design file. TSO Product are providing for free a few designs. Once you have the desired file, it's a matter to find a local shop that provide the service. The price may vary but if you are providing material (MDF sheet) it should be between $50-$80 IMO.
