You were grinding your tool to have a neutral cutting action. Do you not ever grind the tool to have a slight angle on the cutting edge, either left or right, to determine if the pip is left on the part or the stock?

I confess these days I tend to use insert indexable parting tools, and these come in either left, neutral, or right cutting varieties. My rear tool post however has an HSS parting tool that I custom grind to the job in hand depending which piece needs to be the finished part.

Andrew,

That works on small parts, but on larger parts with more tool extension, it can cause the tool to creep sideways and bind up.
