DIY Lathe - What Headstock?

[Chaz]

Have you got a lathe or access to one?

What kind of tolerances can Thor produce?

Given the effort you put into Thor, I cant wait to see what you come up with this time for a lathe, tool turret on the cards?

I have my Emco 120 which Ill sell. Just not big enough for what Id like to do.

Tolerances, not checked yet, should be doing some calibration cuts this weekend once I get a new table installed. I'm also aware that I have a slight offset in my Z axis, getting a bit of deviation across the Y plane, when measuring Z movement. This is due to the spindle clamp I am using, Ill probably replace it or machine something better than what I bought.

I have two main options for a lathe. One, use my massive metal structure that I used for referencing as the base for the lathe, simply bolt rails to its one side, install 3 carts each side, fabricate a simple X and Z Table. Toolchanger, multiple options, id possibly got for a non turret option as its easier (I think) based on a large working area.

The idea is that I get a headstock that I can then just add a nice high power servo motor to and go from there.

Another option is to form and cast another concrete structure but this is a lot more work. I may start with the metal structure, prove the concept, then convert it to Concrete (or make another a decommission this one).
