Actually now that I look at the numbers and do the math my Takasawa Max turn is close to a 16X30 it's 400mmX800mm with a a 5HP motor.
It's 20 or 22" of head stock then add the chuck. Your little gizmo there give me an Idea. I think I'me going to steel that design and make me a copy of that.
I'd rather have one tool that can do multiple things then sleeve each and ever barrel that comes in.
