Is there are formula or rough correlation for a starting (roughing down)
speed as it relates to the diameter of the piece being turned? What do you
use? I have a Jet 1442 (reeves) and if it means i can't safely turn a piece
on its lowest speed, I'll have to make a design change.

I know there are many factors to consider here, including balance of the
piece being turned, I'm just looking to see if my lathe's low end is in the
neighborhood.


Thanks,
