MFT squaring
« on: February 06, 2018, 12:24 PM »
How often is everyone checking their MFT guiderail for square? How often are you finding it needs adjustment?

I've had my MFT for 8 years and have never had to adjust the factory set stops, they've always been dead on. I pull a diagonal measurement every once in a while across panels coming off the table and they always seem good. My cabinets always come out square.

I seem to come across a lot of methods and tools for squaring the MFT, is it all a bunch of drama created to make us worry/spend money on a nonissue?

I check mine at least once per day, but seldom have to adjust it.  There have been several threads on the "how to" aspects; one recently.  If you only cut one thickness of material, it will rarely go out of square, but if you change thicknesses frequently or square it low, then raise the rail, there is a much greater likelihood that it will go out of square, just from raising or lowering it.

I usually check the MFT for square each time before I begin a project. I know it seems a lot but, I have my MFT on a cart I built and I seem to grab the fence sometimes to move the cart around. I think it has gotten to be a habit now to check the MFT.  8)

Rarely do I find my MFT/3 out of square.  I check the cut more often when dry fitting than I do the actual table.  I probably check it at the start of a new project plus whenever I reinstall the fence.

If you adjust the height of your rail to suit the various thicknesses of material correctly it won't go out of square.

The correct proceedure is to put the material under the rail. Release both rail clamps and, while holding the rail down flat on the material, tighten the back clamp.

Now, while holding the rail down flat on the material, raise the front clamp so that the pin indexes the rail and the clamp is square against the rail, tighten the front clamp.

Your rail is now set at the correct height and should be square.

If the material is not wide enougth to reach from the fence to the front clamp you have to either move the material or use another piece of packing that is the same thickness.

I check mine before starting a project. I use a Woodpecker framing square or their MFT special purpose square.

The only time it has been out of square is when one of the fasteners on the pivot loosened.

I’ll always make a test cut before cutting into the real stuff. I butt the top of the wood against Qwas dogs and my rail has the Slop Stop piece. The cuts come out square.
