Holding a concrete pad down!
Seriously tho, check the lathe out for wear and operability. If it is even
a moderately well worn lathe, it will be a valuable item for your home shop.
If you're in the Southern Calif. area, I'd love to come over and do some
work on lens cells for my telescopes as well as eventually doing some mounts
for those telescopes. A 36" swing lathe can handle the large parts that
need to be swung without any problems.
I'd also put a 1 HP. 115V motor on the lathe so that you can use it without
needing 3ph. power although that will mean that you can't take the big cuts
that the original motor would be able to do.
