"Also the back gears are 14 pitch which is an obsolete size tooth size now days. The gears are also 14 ? degree tooth profile and modern gears are usually 20 degrees these days."

I think I have the 14 set, plus one of the old Haas stepper driven rotary tables, accuracy to 1/360th degree. To me it's better to either replace the gear with a ductile iron blank shrunk and screwed in place with 4 setscrews (Turn the old teeth off plus twice again the depth, bore the DI blank to .003" under or so and shrink it on, and run the setscrews between the parting line, little #10s) and then cut the teeth. That's what I did on that Brown lathe but I made the whole gear out of ductile iron, far stronger than the original.
?Having said that I should say the better way would be to talk with a gear hobber, because a generated tooth will be a smoother and quieter tooth.
?Cost maybe $400.
