Re: Breaking carbide inserts parting off?
I have the el cheapo Bauer one and yes it works well but the idea on the

Re: Breaking carbide inserts parting off?

Breaking carbide inserts parting off?
Now I know that for some folks parting off in the lathe is routine, but for

Huh, my lathe only has three steps in the flat-belt step pulley.
My tach is giving numbers that "feel" right, given how fast things seem to
