well, the euro edge finder is much more accurate than my American straight style. The wiggler and the euro are almost a match for repeated centering tests. I re-ground the shaft to fit a 3/8 collet. ahhhh. I am within 2 to 4 tenths of a thou on the wiggler on center repeatedly. It kicks over so much better. I tested both the small and the next larger one.
Before regrind..
After a regrind:
I did manage to break an arbor on the toolpost grinder on the lathe. On the last pass, I turned the lathe on and I thought it fed into the chuck , but it was the chuck that started coming off the lathe spindle. I grind in reverse. On my old Cushman chuck I had installed a set screw that held the chuck on. The new to me Bison does not have enough room to do that. The boss is just too small. I don't know what I will do about running in reverse now. Someone on here mentioned that they glue the chuck on the threads using CA... I'm not so sure I like that idea. Maybe I'll try medium Loctite and just clean it with acetone each time rather than having to heat the plate and spindle to break free the plate.
