Default Tool holder geometry, carbide vs ceramic, trigon inserts

Well, I never got a decent finish, it was so bad you could ridges across the item I
turned. I tried a different carbide insert and it wasn't any better.


By "ridges across," you mean chatter-type? Or was your tool-nose
radius too small for your feedrate?


I was within the nose radius. I tried 0.001 to 0.002 ipr.

If it's chatter, you know what things can cause that.


This is a very solid machine. 22" chuck, 4" dia quill in tail stock, uses 1" sq tool
holders. This should have been cake.
