Re: Keyed Aluminum shaft

oy. For that kind of distance...I don't think you can. But if you're doing small lengths (<7") you can buy a broach, which is a serrated piece of metal that gets pressed across the surface of the shaft and cuts a keyway. By adding pieces of metal underneath the broach (we use sheet copper), you can increase the depth of the keyway. We made all our keyways on our prototype transmissions using a broach.
