I figured out how I might fix this on the ancient Bridgeport M head I used to have, but I exchanged it for a much better J head.
Anyway, I got the idea that I could cut strips of brass shim stock of a thickness of half the total spline gap, and slip them between the spline teeth, and then bend the ends over on the pulley. It might take a bit of fiddling to find the right shim thickness that would fill the gap but not bind the travel of the spindle. ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
