Re: Non-Standard Broaching
We have standardized on 1/8" keys for 3/8 and 1/2 shafts. For smaller gears (12-14T) we cut only the first pass of the broach in the gear and cut the shaft keyway deeper. --For the 1/8" broach a shim is included, it takes two passes to cut full depth.--- We also cut the depth in the shaft at .063", this is a little shallow per Machinery's but works for this size shaft.
Sanddrag, those are the correct McMaster #'s.
