It's a 9" Model C Workshop lathe. Model C because it has no gearbox or power

We have a scrapyard nearby that has a lot of very large motors, but I think
they might be from trains and there is an obvious size limit on those. The

There are more large motors like that around than you might suspect.
The local Omnisource scrap yard had a 6000 hp motor blow and they
replaced it with a bigger motor. I think 8000 hp.
They shred cars and whatever else they can fit into it.

You will have $3-400 into a 10 hp phase converter in no time. (I have
put a few together). If you need three phase for other things.. go the

If you are going to run the lathe a lot, I would look for a relatively

we had 2 of those 9" southbends in my lab for quite some time until I
finally got rid of them. Pretty nice lathes, they look more obsolete than
they actually are. Although parting off something was a frustration. I
tried to buy one, but it didn't work out.

I have a friend who bought one of those as they are collectors items for
those who wish to collect old machines..
He paid well over $500 for a box full of parts along with some broken
gears.. and no tooling at all.
I tried to stay positive when he told me that.

Gene,
You need to remember that the seemingly high hp ratings of these
relatively small motors is due to the very high rpms at which the
ratings are valid.
These 1 1/2 to 2 hp motors develop that hp at 5000 to 6000 rpm. You
will have to rethink your drive coupling system to reduce that speed
