A cheap dial gauge arrived today.
My plan is to 3d print a holder for it that will fit to a block of wood riding on a strip of MDPE that will fit in one of the T-slots of my table saw. I can then check that both the blade and the fence are accurately aligned to the T-slot and indirectly thereby aligned with each other.
It might also be useful for aligning the fences on both the bandsaw and table router, but what are the chances of the T-slots all being “industry standard”? On the whole I’m thinking the odds are pretty slim.
First up is to design the bracket, so it’s time to break out FreeCAD.
