A considerable number of forum members have lathes that use change gears to achieve the correct feed for cutting threads. This leads to the problem of calculating gear setups for a particular desired pitch.

The presentation looked well thought out and so I decided to pass it along for gearheads to add to their reference bookmarks. [Actually, given the finite lifetime of web pages, you may want to copy it and store it locally.]
