Default Pick-up / drag lines turning mild steel

Hi guys,

I've just set up a Victor 16 x 40 lathe and did some practice turning on a
2" hot-rolled mild steel round. No matter what variables I played with I
never got a satisfactory surface finish. The tooling seemed to pick-up or
drag metal, and this would lead to small gouges in the finish. I tried
various things, but never could eliminate it consistently.

Any thoughts?

Thanks,

Damian



Cold rolled (1018) causes the same problem I have had much better results
turning 4140. It seems to be a good general purpose steel that can also be
tempered a bit.
