Hi, after doing some research, I decided to just build a KMG clone. The thing is closing on the backstretch, and I am having an issue with my tooling arm. I have used a wilton square wheel grinder before, and really like the interchangeability of tool rests and wheels/platens.
So, my arm is drilled and tapped at the end, a half inch hole for tools/wheels, and I slit the bar with a portaband. My problem is that the pinch bolt will not lock the half inch bolt I am goint to use for wheels and such.
After this failure, I decided to widen the gap with a cutoff wheel on my 4.5" grinder. Still no pinch.
Any idears?
