Hey thanks for the info (not what i wanted to hear) but what is a quandrant rack?
The reason why you ask - I want to use a gundrill to drill a .667 hole 30''s deep into some 4140 and the people at Sterling Gun Drills said that I needed to get my feed down to at least .001 for this to work. There must be a way to do this with gear changes ( I would think) any ideas on what the ratio would be.
Thanks,
Sonny
