How to make a radius tool for the lathe?

[Shiseiji]

What about a router core box bit?

Darn phone jumped into the "You haven't joined any chat rooms" (NO and I wish you would leave me alone) like should have been to a Lee Valley 5/16" cove box bit.

I don’t know what that is?

I found and reground a tool bit with that radius. If you want it let me know.

Thank you Jim,
I got there in the end. I just rounded an existing hss cutting tool i had ground for facing. Ran up to the shoulder and pulled back.
Close enough.
I liked this style knob but had the wrong thread.

After you have ground a radius about a thousand times it’s becomes
easy.
