My approach depends on the construction square for “squareness” and not the location of the holes in the MFT-style top.
I select any three convenient holes for the standoffs. And slide the construction square in place.
The standoffs are approximately 3/4” x 2” x 3”. I cut a groove suitable to accommodate the thickness of the square. I added a dowel to fit in to the MFT-style top.
The first image shows how I would use this to join face frames.
The second image shows the profile.
The final image shows how the square fits into the standoff.
The height of the mounted square is approximately 3/8” + the thickness of the square. That height keeps the stock from jumping out of the capture of the square. It also allows for significant pressure into the corner.
I posted this a while back in hopes that someone would make a 3D printed version. But my cobbled together pieces work exceptionally well, so I am satisfied with my effort. But if anyone wants to, they are free to copy. This is not a protected design.
I’ve made three work benches with MFT-style tops. In each case one random hole is slightly out of alignment. I resolved that issue by using a marking pen to outline the offending hole. I have no idea how the errors crept in. I was working quite precisely.
In any case this approach bypasses any machining errors. I have two different size steel squares and a straight edge that all work fine with these standoffs.
I would not describe this approach as “better” but perhaps “more forgiving” would be an appropriate label.
