    Hi GinoS,

    I think you are looking at the charts on the right hand side, which are for "Module" and "Diametral Pitch".

    ztugdriver,

    Notice how the original gear teeth are slightly helical.

    I am guessing the teeth are an involute form, but I know very little about gears!

    A worm wheel of unusual proportions?
