You are saying that you are retrofitting same model of this machine? If there is a chance, I would rally appreciate to see design that you have.
I agree, I was also considering to mount gearing directly on pinion shaft that drives quill up and down, but I think there should be some decent amount of force applied to quill in one direction (probably downwards) to eliminate backlash as much as possible. I found this thread about retrofitting an old RF mill/drill and he also minimised backlash by reversing spring... http://www.cnczone.com/forums/benchtop_machines/152240-hf_round_column_mill_drill_build.html > > I am busy with mine at this very moment.
