Got to start somewhere.
Rack and pinion drives for the x and y axis are popular and seams to make good sense. Thought about ball screws but don't need that kind of precision and I'm worried the dust from the torch would end up eating them. Acme threads with anti backlash nuts I think would be a possibility.
Any thoughts?
If I go rack and pinion how crazy would it be to manufacture my own. Lacking a tool grinder, I could build a simple jig to set the 20 deg angle on a HSS cutter and grind it on the bench grinder. Then cut the rack 10 1/2 inches at a time on the shaper, index the blank and start over. The same cutter would make a hob to cut the pinion.
I know dreams of having too much time on my hands, but I need to get a metal fix, been spending too much time around wood.

Free advice is worth exactly what you payed for it.
