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

my first lathe was a 9 inch logan ... needed a crutch approach to do cut-offs. now I have a 13 inch Southbend ... seldom have trouble with cutoffs.

Breaking carbide inserts parting off?

Re: Home Shop Machinist Magazines
Jim,
Thanks for the update. I'm glad they found a good home.

Re: Slot-milling worked out on my 10k
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

I don't know the spindle speed -- I have a tach, but haven't measured &
written down the speeds at each setting -- as fas as it would go with my
