The ol' bolt in place of the square key trick.

I like it. Even if you don't use it in the initial build, it's helpful to take note for quick repairs in the field. It DOES work, and works well.

Better than taping 7 hacksaw blades together and trying to cut a keyway because you didn't have an arbor and broach. At least thats what the students told me.)
