Be prepared to move the carriage in X bec of tool drift -- I've
never parted anything that didn't wind up convex or concave,
unless it's very small diameter, or tubing.

Whenever I have to loosen the toolpost or compound I reset it
square with the parting tool holder pressed against the end of the
spindle.

Oh yeah, I knew I was forgetting something.
Which is proly why all my **** comes out convex/concave..... lol

I should add that my parting tool holder is hardened Chromoly,
precision-ground to aerospace tolerances by elves in Switzerland.

Very large, well-armed elves.

If yours came from a Chicom prison factory the blade may not be so
precisely parallel to the end of the holder.
