My workbench has a 1.5" thick top made of two sheets of 3/4" plywood sitting atop a 2x4 lumber frame. It has worked very well for my needs since 1998. I have modified it with 20mmx96 dogholes and some t-track. It's 3'x6' and sits 36" (920mm) from the floor. Along one of the 6' sides I added a dovetail grid 2x4" (that accepts both MicroJig and Festool dovetail clamps) in lieu of a vise. To this grid panel, I can also add accessories like the DashBoard Track Stars and a 3D printed rail support.

Recently, I purchased the MFT/3 side rail to mount to the opposing side of the workbench so that I can add the rail hinge and any other MFT/3 accessories. I stopped by my local dealer today to see the spacing of the rail to the top of the worksurface and it seems that the MFT top is 19mm MDF that is 7mm proud of the top edge of the side rail.

How critical to the use of the MFT/3 accessories is this 7mm? If it is critical then I'm thinking of (somehow) routing off the lower 3/4 ply layer to fit the rail.

Thoughts?

I took some pics - but in one, it looks like the MDF the 19mm thickness I mentioned with 7mm above the rail - however the other looks like the MDF is 15mm?

Thanks!

Well if you are going to use like the adj. miter bar(s) or say in my case the TSO extentions (the sm. Router table as well) the height has to be right to flush out with the top….second pic is a crown stop for example…I don’t cut angles with the MFT stuff anymore but I think many do
