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,

jc

George, Good advice, I agree with you completely. Well almost
completely. In my turning experience, it's Devils dancing with
Pitchforks instead of Angels with Wings. :)

Joe, you might want to look in our archives under harmonic balancers. At
one time we had much discussion about them. They seemed easy enough to
fabricate and appeared to work, but haven't been mentioned here in a
while. Perhaps if someone is using one they will pitch in or somebody
will post a reference.
I assume that your lathe's drive doesn't allow for a slipping belt
clutch? If your lathe will swing it, there has to be a way to turn it.
Good luck with your table.

No problem. you'll be fine at 450 RPM.

I assume that pedistal will be hollow. It sure would make for a heavy table
otherwise.

Here's a web page with a nice chart for turning speeds. I keep it posted
next to my lathe for a good reminder to be safe.

Good luck in your turning.
