South Bend heavy 10 is the F350 of the lathe world. Anything in great shape is tough to find affordable ....just like an F350...
I've got this lathe twin in jet brand....mine had a vfd added when I bought it ....I use a 9 x 20 from Enco.
It took some work to even be a usable machine. But.....for 1100.00 it was a bargain. With good chucks and tooling, it does a fine job.
Lathes are similar to chainsaws. Once you start by purchasing one you just gotta have more. I have three working metal lathes and a fourth small collector piece that is small enough to be a wall hanger. I am an old retired machinist and have a small machine shop in the back yard to play in.
You win. I wish we were neighbors.
If you have the space and means to handle/transport it, a used larger lathes can usually be found cheaper. Everyone wants the benchtop Myfords, South Bends and Atlas lathes which drives up the price.
