Richard, you continue to impress!

Pretty inventive. 

Q:  To adequately support a full sheet of plywood, how many arms do you use?   4 x 36, or more?

Glancing at your photos, and that is a half sheet, yes?

Thanks

Tom

Thanks Tom.

For cross-cutting a full sheet of plywood I use (4) 42" arms. The frame (table?) in it's current iteration is just under 60" long. If I attach the arms end-to-end at the front/rear of the frame I have 84" of support in 2 parallels roughly 30" apart, if that makes any sense. I always try to cut across the support arms at 90 degrees to the MDF.

To rip a full sheet I normally turn the arms 90 degrees so I have all 4 parallel which give me about 42" deep by <60" side-to-side of support, works okay to support a full sheet.

There is a setup video here if you are interested. I will be posting photos of the possible configurations at some point when I get to it.

Richard, I made 4 of the arms in about 40" length (8020 sale). Modified slightly so that the mdf fence is flush w/ the bottom of the arms.

Used them to cut down a 4x8 sheet with no difficulty. There are obviously a number of ways to arrange the arms so as to faciliate the particular cuts.

At any rate, one of the most simple, effective, jigs I have ever used.

As far as I am concerned, these are a MUST for the MFT/3 and it's older sibs.

Truly brilliant.

Too True! [doh]

The good news is that the extrusions can be re-purposed as needed. Most of my 80/20 is on it's second or 3rd job, they just keep getting shorter and collecting more holes. Every now and then I buy a couple 8' sticks to refill the pipeline.

Glad you found them to be useful.

Couple of questions.   By flush with the bottom of the arms, do you mean, flush against the table, or in terms of length (40" long);    it's not flush on the support / cutting side, I'm guessing!

I've got 4 x 48" extrusions coming.   No harm in a little extra length, I'm guessing.

On the 8020 sales, is that all through the ebay site, or via 8020.com or whatever it is.   The sale items weren't jumping out at me.

You are correct that it is flush on the table side. I left the sacrificial fence 1/2" proud of the extrusion on the cutting side.

With 8020, you need to go to the seller page (8020 grage sale), then you can sort by what youi're looking for or just the sale stuff.

The length isn't too critical. My pieces were on sale. I would recommend closer to 40" than 36" to allow more flexibility.

Just came across this post and thought I would show you what I concocted for my MFT/3 after seeing a number of options on Youtube and the Fog.  I use my garage and require a dry day to do any real cutting in my driveway. I wanted to do something to enlarge my MFT/3 but needed it to be simple, cost effective, and easy to store. These pictures show the storage and assembly. I use two quick clamps to secure to my table top so there is no tipping. My parallel guides and extensions fit just right. I have only just started to use this setup and am really enjoying it.

Excellent!  Now that you are using it do you feel that you needed to double the ply?

Hi Ron, That is a good question. This setup feels very solid with what I have used it for, but I haven't cut any full sized sheet material yet. From a strength perspective, I suppose you could use a single piece of ply.  I have always liked to double or at least support a single piece of ply for the additional stability.  I choose the double 3/4" ply to accommodate the 3/4" dowels I used to position the pieces on my MFT. I like solid and I like stability.

Thanks for your comment.

I really do like your construction. 
My thinking was for a set that was a little cheaper & more disposable -- possibly using Domino tenons instead of 3/4" dowels.

That is a great idea. I just checked and the domino fit in the MFT is really good; the dominos would provide the alignment and a clamp or two would hold everything in place. From what I have seen with other systems on Youtube,  one piece of 3/4 ply would probably be sufficient. This idea just never entered my mind, I wish I had thought of it.

Fletchtool,

I think with a couple of Kernov style saw horses and your gridwork, a quick cutting table for sheet goods could be set up in just a few minutes.  This way if you have a garage or driveway to set up in it might be easier than moving an mft around or having to clear an area around it to set up the gridwork.  The gridwork could be easily clamped to the cross bars of the saw horses to keep it from moving.  I think I just talked myself into another shop project.
Also with the Kernov saw horses you can make them any height that is comfortable to cut at.

Also Richard,
Here I am using your idea of the arms made from 8020 with sides, used as extentions for the mft to cut some sheet goods.  Works like a dream  and only takes seconds to attach to the mft.

Thanks,
Rusty

Rusty - nice setup! The arms come in handy on a crowded shop.

Fletchtool - I like the torsion box setup, simple and effective.

Here are a couple photos of my setup in use yesterday, building some stands for our container garden. Tomatoes and peppers are popping out, yum!  [big grin]

Hi Rusty and Richard, the Kernov style saw horses look great and the arms made from 8020 with sides got my attention as well. You know there are so many great ideas for set ups that you could spend all your (or in this case my) work time building them instead of "real projects" that others in your household wish you would complete. I am beginning to think I might really like to have two working surface setups that I could use at the same time if I needed to and now I know what I can do to make that happen.

The FOG rules ;D

So, I just finished building Richard's cutting rails.  Haven't used them for cutting, but they look slick, for whatever that is worth!

One minor point:  I had some trouble finding flat head cap screws that would work well, at the depot.

I found stainless there, but nothing cheaper in 5/16th.

The other issue is length.  If you are going to countersink them, as I think you should, 1" long is probably a tad too long.   I used 3/4", but had to countersink them deep.

7/8 would probably be perfect, but I couldn't think of an elegant way to trim exactly 1/8th off the one 1" screw with some guarantee of not screwing up the threads (NPI)

Anyway, if anybody has a source for cheap 7/8" cap screws, I'm all ears.


Nice, design, Richard!

I also made those awhile back.  Great addition to both MFT and my Walko table.

I also had to countersink deeper as I could not figure a way to shorten the screws.

So far, no issues and very pleased with the extension arms.

Would love to see a complete Bill of Materials for the table, Richard.  I think I saw some on your blog, but there are still some special joining pieces that are not clear.

Love 80/20 stuff!

Not elegant but when I need to cut a bolt I double nut it with whatever I want to trim exposed, clamp it in my vice and take a hacksaw to it. Unthreading the nuts straightens any possible thread damage - then a light swipe or two with a file to take any sharp edges off.

Thanks, guys.

Richard:  any downside to using these post-clamps for other jigs?/ home made fences etc. 

I haven't been able to unbury the mft table from the soon-to-be-gone pink insulation, but guessing there's a little slop with a 3/4" spacer?

No downside but yes, they are a bit sloppy in the MFT holes so accuracy/repeatability is not built in. Also the 8020 t-bolt I used don't fit any of the other t-slot material I have, i.e. Incra, Woodpecker, etc. You can correct this by switching to some other bolt.

Here are a couple recent photos of my setup in use - I attached some of the 8020 to my MFT to extend it out and I have the dedicated cutting table as well. With the new deck outside my work-shed I now have a bazillion times as much "shop" space, at least in nice weather.

Richard, you're the Jonathan Ive of woodworking.

The extension you made....was that using the 1.5" stock?   Was the top of the extrusion flush with the MDF?

Would love some details on this.

What's the minimum you need to create a stable extension?   Cross bars top and bottom?

Also, can the t-slot on the side of the MFT handle all the weight?

Thanks,

Tom

Thanks Tom. They are 1.5" extrusions, attached to the MFT with slotted L brackets so they can be flush with the MFT top or lowered 2" to add the arms with the MDF and make them flush to the MFT. There is no problem with the MFT extrusions carrying the load.

I will post some photos and details as soon as I get it set up again.

The L brackets.  Do you make your own?

I've found a ton of L brackets, but few with slots that seem right.    I don't have any milling equipment, and making my own slots, I can't think of a way that isn't hacky.   Holes plus file.  Holes plus jig saw plus file.  etc. 

Not even on 8020.   Although that site is overwhelming.

Like the Smithsonian for guys!

That is the rub... I grabbed some surplus "custom" brackets from 8020 on eBay, apparently they made them for some customer and these were leftover. Not a stock item.

One bracket is mounted to the MFT/3 and the other to the bottom of the 1515 extrusion, the slots mate up and let you adjust the height by 2"+ with a carriage bolt/knob.

Mason Plastics has a similar bracket used for industrial conveyor systems, but I have never attempted to purchase from them so I don't know if they will sell in small quantity:

I will try to tinker with it over the weekend and see if there is something off-the-shelf that will replace this setup.

SC - Glad you are getting some use from the idea.

I was fooling around with a couple of the Kreg Automaxx clamps I just got and stumbled onto a simple way to use them with the extension arms. I basically just threaded a 5/16" by 7/8" long FHSCS into the hole until it bottomed out. This leaves about 3/16" under the head, just right to slip into the t-slot on the 1515 extrusion. I ended up grinding about 1/16" off the thread length after taking the photos to tighten up the fit, but I really did not need to as they worked fine with the 7/8" cap screw.

89490-1

89492-2

89494-3

89496-4

I will say that, while I love the ease of use of the clamp, I am disappointed in the overall fit/finish. The original clamps (pre-automaxx) were cast or forged, this one is stamped and a somewhat sloppy job, the threads are not even close to perpendicular with the clamp base (2nd photo). Overall they feel a little cheap considering the cost, hope they hold up to heavy use.
