Rotary table/dividing head calibration with theodolite

A note about damping grease; NYE makes some excellent versions. In optical instruments , it is hard to beat the silky smooth feel with the proper grease. I suggest you use the extra light damping grease, even medium has much more drag than you would expect.

Wasn't that you who said much the same thing in post #9? Don't feel bad, I've been developing a case of CRS for a while myself. :D
