Re: Securing Machine Keys

A set-screw isn't a bad way to go, I've drilled and tapped set-screws with a cordless drill and hand tap. I like the set-screws with knurled or pointed tips and a little bit of blue Loctite to keep them from backing off.

Recently I've come to the conclusion that as along as the key can't slide out along the keyway it will be fine for FRC purposes. Close-fitting axle spacers work well, and this year we've tried peening the keyway closed at the end, so far so good.
