Lathe Tool Holder Rigidity Theory Question

[G-ManBart]

Ok, I’m done with this round and round foolishness.

The answer has obviously been predetermined so any conversation on the matter is pointless.

You never addressed the question at hand, so it's probably for the best.

No matter how you twist and turn this, a tool milled to 3/8 x 1/2 will perform as good or better than the 3/8 x 3/8 tools the lathe was designed for. It might even perform a lot better if the carbide is thicker.

Twist and turn....classic lathe pun!
