Hi Folks I have recently acquired one of the little 7x12 minilathes. Its the metric model and came with a small box marked "gear wheels for imperial threads". I want to cut a 32tpi on some 1" brass bar. I note on the `Little Machine Shop minilathe manual` that to cut 32tpi I need gear wheels 20,any,any,40 in the order A,B,C,D on the gear mounting. Will this give me 32tpi without a different leadscrew?. I see that to cut metric threads with an imperial lathe a 127 tooth gear is reqd, is there a similar requirement for cutting imperial threads on a metric lathe?. Cheers Steve
