Hi everyone. I expect most of us have charts etc that give us all the information we need.

Re: Parting Off
I do it upside down, in front of the work, with the motor running backwards (clockwise as you face the spindle).? Works great.

Re: Parting Off
I too use a "norman" style tool post, but mine is mounted on a 1.0 inch
diameter post.
I works quite well and I have been using it for about 20 years now.
Drawings and photos are available.
