Umm, use a keyway broach? That is how you make keyways, you said it
yourself. I'm just messin' with you, but seriously that is the best way.
If you don't have a broach in your shop (which I would find hard to believe
that a machine shop at Cornell does not have a broach set) you can buy them
from McMaster or machine tool supply stores. However, if the clutch is heat
treated or hardened a broach may not work, and you will probably have to
make your own bushing for the broach since the Polaris clutch shaft is a
funny shape and size. The only other option I could think of would be EDM
or something like that, but that would probably be more difficult to obtain
and expensive. Good luck.

Hi all,
We need to broach a 1/4" keyway into our Polaris CVT and I was wondering
if anyone perhaps had a simple and quick way of doing it?
Thanks,
