i have a project i am in the planing stages of that requires a 14x1 LH internal thread. a tap is over 30 dollars and i only need to make one or two parts that use the thread. i plan on doing the project on my dads south bend 12 inch, flat belt drive, motor under the bed with quick change gear box lathe ( sorry i don't know the model number) he said he has the metric conversion gears but can't remember how the pitch then correlates to the gear box setting. can anyone help me out here? i'm sorry if i have not given enough information let me know what you would need to help me out and i will try and obtain it. also i am assuming the threading dial is useless with metric and i will have to reverse the lathe to reset for the next pass.
