I'm not a wood turner per-se, BUT I do "turn" things. I'ma model builder and have a full miniature machining center to play with Aluminum, and even plastics.... I turn just about anything with it including wood, but seldomly turn wood on it. I also have a mini-Wood Lathe made by Dremel! Which I have used for wood turnings a bit more then my Unimat!
It goes down to almost zero.It looks like a regular machine lathe chuck with reversible jaws but the body is only like
1 3/4 od.Great for doing small stuff.......
So its a full headstock then (you mentioned reversible jaws) so... thats AWESOME!!!!
I'd KILL to get my hands on a independent 4 Jaw chuck for my Unimat! And a small collet set, GAWD, I'd be damn near unstoppable then! And a 3 inch rotary table!!! -Heres to dreaming...... LOL
