I did a video showing the Radius / Ball turner I built a few years ago. I take it apart to show how it was made then I show it cutting a concave and convex radius.
Thanks! Simple, rigid and operative mount, and a clever greased register bearing,
doing away with any ball bearing that'll just add stack height and less rigidity.
Nicely machined insert holder also, but did you mention the inserts' rake angle?
You might consider changing the set screws for brass dog points, to avoid marring the holder, tho.
