I'm starting to research building a CNC lathe. I'm thinking 2x3'ish steel tubing with 2 linear rails to support the carrage, with a slot between the rails for an extended arm that will attached to a ball screw which is hidden in middle of the 2x3. ((if that explains what I'm planning on doing))
I have a few concerns at the moment.
1: what should I plan for the top rail that the tailstock locks into/onto? One a normal 7x14 type lathe, the way is cast on the the way.
I was thinking that it might be possible to get someone on here to mill out a set of rails that would be mounted on top of the 2x3 and welded in place? Does this plan have any flaws, asided from my in ability to machine anything that large.
2: I was looking at using a 7x14 style head assembly, but I was wanting to get a large through hole. Is there a comparable head assembly that can be ordered that would fit my needs?
Does anyone have set of prefered links for homebrew type cnc mills?
Sorry if my description sounds vague. I'm still in the thought process.
Any concerns that experienced builders see? Will it work or a bad design from the start?
