A pair of Tufnol  fiber tumbler reverse gears to fit the Myford Super 7 range of lathes.

Remember - Myford designed these gears for quiet running and also to shear in the event of an accident and so protect the rest of the lathe and drive train so...

buy a set now and have them as spares just in case.

! ! ! Remember ! ! !
you have no way of knowing when one of these will strip normally late on a Friday night

These are machined from plate Tufnol as the circular weave of the rod form makes for a weak gear.

The illustration shows one pair of gears together with the results of a jam.
