Rex,
Maybe I missed it.
How are you locking the T body into the T-slot?
I’m thinking a simple 1/2” thick top strap bolted into the center of the T body.
So far so good. Working on the one piece T block now.
I have a 5 degree back rake on the carbide.

This is my design and I have been using it for years . I have no problem with finish. And if you make the tool like i do you don’t NEED any relief. But if you want Kennametal and others make a 1/4 inch round carbide insert that is shaped like a ice cream cone that works perfect for the turner.
i don’t know why but everybody wants to make my design BETTER .
One other thing most people cann’t seem to get in their head is the same SIMPLE
tool does is two functions it cuts balls and it also cuts a radius into the od of a bar.
Another thing my tool can easily be made without a mill. It can be made on a lathe with ease and you can control ball or radius size to a couple thousands
true size. Making a 1 1/2 ball is simple if you need that size.
A simple puck can be made for many different sizes very guickly with ease.
I know Rex has seen my tool working for a ball shape or a radius cut into a bar
od . And Jeff you know and have seen some of my tools work.
And before you start making a ball turner give me a call
and I will be happy to explain more about tool.
you can also google Jimsehr ball turner to watch it work.
