Been awhile since I posted in Chaski, but I'm back....

Acquired a Southbend 9C lathe last Fall and will be restoring it to operational condition. Judging by the serial number, it was built during the war. A previous owner painted it blue.

Created a heavy wood stand for it, set the lathe up on the table and will have to inspect the motor. I saw something I didn't like....

There will be pictures posted this weekend.

I can't say what you "didn't like" but the underhead motors of the 9A are quite heavy. I can't see that motor positioned outside and the heavy pulleys. Then it went to flat belt and those were relatively heavy cone pulleys. So I don't see that happening without under drive.
Way back in the 1930's, with the South Bend 11" they changed so where an electrical motor could be used instead of line shaft drive. The motor is enormous and heavy and the cast structure to support it and the chain drive and flat pulleys weighed a lot! Sure it was stable with all that weight. We don't see many of these around anymore...But there was centrifugal balanced force to the spindle. I cannot more recommend that, after all this time, a flat-head engine but it did do the job.
Your 9 is different and what it needs is stable drive. You can't hang all this weight off of it now. One balanced flywheel will help and the newer options can work with it.
