Re: Bigger then a Sherline WAS: wrong guy, but have servo question.

Smoke,

Yes, the kits sound good. A few castings can go a long way then. I'm
interested in mills for now. Do you have a pix of some similar
construction you have done? Can these dimensions be scaled down
slightly if needed to fit "existing" (my junk box) ball screws?
Possibly only the ways would need to be changed?

I will check out Lathe2000. Please keep us posted!

PS, D1-5?

I've posted plenty of messages at the Lathe2000 egroups site about this one. It is built from standard structural steel components, is "bolt together" construction and uses round ways. A similar one will soon be available using "common castings" (same casting used in multiple places) but uses box (rectangular) way construction.

That's about the cheapest way your going to get any kind of machine unless you build all the parts yourself. At present, I have NO price figures to give anyone. All this does take time to set up and get started....especially when I'm the only one working on it.
