I've stated building a metal lathe for myself. Funny enough, it started out because I needed a way to cut delrin rollers to roll in extrusion for a delta 3d printer I want to make.
We'll see how soon that get's built, but I'm excited about lathe stuff now.
So far I've got some 15mm rails for Z axis, and 25mm rails for X that will be mounted upside down.
I was planning 15mm and 20mm rails, but found a good deal on the 25's, and now after seeing how small the 15s are, I might look for some 20's to replace them
Everything will be build off of 30mm aluminum plate, that I am cutting from an unused table top I have.
Ballscrews are 1605 chinese ebay ones, which I am dissappointed with so far, but we'll see how they do.
some pics and a video, I still have some stuff to figure out, and the z rails and ballscrew will definitely be covered, I will try to make a telescoping metal cover.
If that doesn't work out, I look at other options.
