Topic tags/keywords: miter gauge incra table saw jig

I tried making nice picture frames and I was having trouble getting my miters dead on. I decided to buy an incra miter gauge, and can not get the thing to cut square for the life of me. I checked my table saw to make sure the blade is parellel to the miter slot. It seems like every time I get the gauge close (with .010”) and I try to make the final “fine” adjustment I can not get in there. There has to be a better way than just loosening the allen screws and nudging the fence! I am beyond frustrated with the thing. After doing a little more research, I wish I had bought an osborne. From my understanding, they actually have a fine adjustment cam built into them! Regardless, any suggestions on calibrating the incra 100se that I already have? I have a digital caliper and a dial indicator, but can’t figure out a way to put them to use to get this thing dead on.

Put paper shims in between the gauge body and the fence. That’s
the way I have done it for years. You can only get so close, as
you’ve found, with adjustments that involve moving a part into
alignment and then tightening screws. Errors in concentricity
and alignment of screw holes and so forth.
