Thread: Lathe turning finish help

The tool was set a little high, and the carbide tip was gouged or dull or something. It's a good thing I bought a box of ten tips on sale. I've been using this same cutter for everything and just changing its orientation for facing and spindle work; reverse turning gets me into facing mode. I got a pretty good finish when I took a huge cut, cranking on the x-feed about as fast as possible (even using a dull tool), see first picture....

That looks like it could use some support from the tailstock. Might not cure all your problems but should reduce your workpice flexing.

try changing the tool, you are using a boreing bar. use a small rad tip to minimise push off.
