I just made a stop for my ER spindle so that I can change tools repeatably:
Spindle Stop
As for speed changes, get a Sherline or other VS motor that uses a KB speed control and see if you can get Peter Homann's Digispeed to work...

Yes, you usually need heat to remove the pulley, and it usually ends up being a frustrating experience...

I still like the idea of going to a variable speed setup that I can program the RPMs for in code, any one have any suggestions?
BTW the bloodied knuckles were from trying to get the damn pulley off, for some reason it was really tight on that spindle and I had to use a heat gun and large wrench to pry it off. |
