Source for old South Bend lathe parts
The lathe I have access to is a circa 1941 South Bend heavy 10 in x36 Navy Signal Corps lathe.
The threading half nuts have worn.
I did some searching and found Grizzly tools is handling the spare parts for old South Bend lathes.
I was able to buy a new,original set of half nuts from them.
You must have the serial number from your machine before you call them.
