MFT 3 ideas for small shop
« on: February 13, 2018, 04:35 PM »
I have a small 8’x12’ shop in a shed.  I have used the MFT3 and TS55 as my primary saw.  I keep dust down with a Pro5 sander, a Trion Jigsaw and Domino. The  Festool system has allowed me to have a relatively dustless efficient space.   I made some changes to the MFT3.  I use the MFT as my primary workspace and need to have a clean space on the table and keep as much space left in my shop. 

First, I basically never use the protractor and wanted to both maximize my cutting space and keep the table pushed close to the back wall.  I ordered another fence clamp and use two clamps to hold the fence on the table.  I added a Kreg scale on the front, so I can use a flip stop for measurement. i set up using a carpenter’s square at exactly 12.5” on the flip stop of the fence and squaring up against some veritas dogs.  It squares the fence and gets it set for dimensioned for cutting.

Second, the current hinge mechanism was hard to open and lock from the front of the table. I got inspiration from Sean KS on this forum (thanks).  I replaced the Festool mechanism on the back of the table with a linear guide and a 1020 Extrusion from 8020. its not as pretty as his though. I attached it to the hinge plate for the guide rail.  I added a bolt to the 8020 so at its lowest the guide rail sets right at the fence height when lain flat.  With any wood piece against the fence the guide rail hinges moving the 8020 piece up, perfectly lying flat across the top of the piece to be cut. Most of what I use is ¾” but I have used it up to 2” and tested up to 3”.   It does not need to be locked at height and has no movement side to side riding along the bearing. 

I can set up the table from completely clean times in 2.5 minutes.  Since it is new I have checked square and correct dimensions each time.  They both have been perfect each time. I can keep my table pushed back saving several inches and don’t have to lock the guide in place to cut. I can have a clean or set up table with very little effort.  It has been a game changer for me.

People might have seen this from another thread, but if you have access to a 3D printer I designed these clamp dogs which can be used to align the back fence of the MFT with the dog holes: https://www.thingiverse.com/thing:2754628

I actually saw them.  They are fantastic. I didn’t have access to a printer so I bought the extra clamp. It did give me a little more cut width. I ended up with 25”.  I wanted to get to 24” for a couple of projects.

The 3D printer is such an amazing tool. Impressive what you did with it. Maybe I will have a chance sometime to use one.

Thanks.

Did you have to trim the Kreg Tape? I have tried 2 or 3 different tapes and it seems like Festool designed the fence to be just shy of 1/2 inch so the tapes either have to be trimmed or you leave a little on one edge or the other.

It does overhang a very little. It doesn’t seem to be a problem yet. I could imagine that it would at sometime in the future. The tape is very rigid and the adhesive feels very strong. If it comes off I will try to trim somehow next time.

Thanks Sean. Pics aren’t great.  I plan to clean up the connectors on the linear guide (don’t like the nut/bolts) and something better than the bolt to keep it sliding down.

I had planned to trim the hinge plate and put in a lever brake but quite frankly I am not sure I will ever need a brake as it works so well without it.

But it works great and saves space and is so much easier to set up cuts.

Yeah, looks great.

How easy does it slide up down with the bearings ? I'm guessing that they're some super sliding plastic or nylon ?

Reaching across the cable to adjust always been a pain.

It works way better than I ever expected. You can add shims in the bearing to make it very tight if needed. I have it just tight enough that it slides easily but has basically no movement side to side. I lift the guide guide up and then place a board down against and the fence and when I pull the guide rail back down the extrusion moves up the bearing to settle at the perfect height. I see no reason to lock it down in back at all.

I will try to post a short video tomorrow. I’m new to this but I think I could post a YouTube link.

I hope this video shows how the guide rail self adjusts to the different heights of boards with the new mechanism. At the end I also tried to show that it was very stable side to side. This is without using the front mechanism of the Mft. Obviously when I am using the table to actually cut I support the front. 

I used 3-3/4 inch boards to represent different heights of boards and how it adjusts itself. I see no reason at this point to lock the back linear guide. 

It seems a little difficult to get the extrusion into the linear bearing but I had the phone in one hand and tried to watch through the phone screen.

Great thinking!!  That has always been a gripe of mine that I had to reach across the table and fiddle with the clamp to raise the rail. I just took mine off and use dawgs.

Great ideas!  Do you have part numbers or a link to the 80/20 linear unit you used?

The 8020 parts were:
Linear bearing 6424 (it came with several shims, maybe 20+. I used 4).
https://8020.net/6424.html

Extrusion 1020 - cut to 9”
https://8020.net/1020.html

I bought a couple of T-nuts. 25-3382
https://8020.net/25-3382.html

I used a couple of 1/4-20 carriage bolts that I filed down to use to attach the linear bearing to the table with a couple of hex nuts. I need to order a T-nut and and maybe a couple of socket cap bolts to replace them. Would make it easier to remove the linear bearing from the table. I couldn’t find anything better locally.

Hope that helps.

Simply excellent execution on this modification.  Kudos to you for crediting the source for your inspiration and also for taking the phone video in the horizontal mode.  Well done  (and soon to be duplicated on my MFT  [big grin])

Thank you for this, and the part numbers. I'm going to do it if I can just get over my analysis paralysis of trying to use linear bearing solutions - which admittedly are overkill. This is for a custom 4x8 cutting table I'm working on that has been inspired by various projects I've seen on FOG.

Overkill, when leading to getting the job done, is a good thing.
