Hello. I have a Jet 12 X 40 lathe. I don't have a 4 jaw chuck and badly need one. The spindle is threaded. The manual says it is 60mm by 8 tpi. I thought that was weird. I cant find a chuck or back plate for any metric diameters. What can I do? Thanks in advance.
They do look very much alike. I can't quite read your mfg date. I think it is 1966 or 86. Mine is 1983. Hopefully you can measure your spindle threads and find one easier than I can.
