Hey Group,
My 18" Okuma LS lathe's 50T phenolic gear is cracked... I have a piece of 3.5" phenolic rod and was getting ready to make a new one but I have a few questions. I know other Okuma owners have replaced this gear, and a lot of others here have much experience machining gears, so maybe someone could help.
The steel splined center hub looks like a pain in the butt to machine a gear to mate with. Should I make a gear from 100% phenolic, omitting the steel hub? My gut tells me it might not last long. Maybe machine a new non-splined hub and attach the gear with Loc-Tite or epoxy? Skip the phenolic altogether and make a new gear/hub from solid brass? Or something else?
My other question is what gear cutter to buy. I have a mill and rotary table, as well as a gear cutting book, and no doubt could study, measure, and figure it out, but if someone knows offhand what cutter I need to buy I'd love to get right to making chips. Thanks!
Regards,
Jon
