Keyway slotting

[CrabtreeengineerParticipant @crabtreeengineer]

Recently I took on a mission impossible job that involved cutting keyway slots in seven hardened gear wheels. A broach would not look at the job & the teeth just ran smooth on a square file!

I found a work around by roughing out with a small Dremmel & then cleaning out the corners to full size using a HSS cutter in an old hand powered Adept shaper.

The Adept is pushing 100 years old yet I wouldn't dream of parting with it, worth its weight in gold! Get one if you can.

I have it set up to the centre height of my rotary table & set them both up on a milling table.
