Had to share this picture. I had a cam with a roughed-up nose, so I worked up this polishing set up. It's an M10 threaded rod in the end of the cam (or bolt with head cut off), a nylon washer and a nut to hold it in place. The bolt is then clamped into the drill chuck, so I could spin the (well-oiled) cam and polish the nose with emery cloth from harbor freight. Worked like a champ. Collar wouldn't fit at all to start, but slides on smooth as silk now... Just thought I post up in case it helps someone down the road...

That is a freakin' great idea !! Well done

Alternatively, if you take a 1" strip of emery cloth and work the cam snout (or a crank snout) with a 'shoe shine' motion, it cleans up quickly. It's usually either the keyway area or the tip on the snout that gets slightly buggered.

No need to spin the cam. This method doesn't take much time nor effort.

I did try that for quite a while, as it has always worked for me in the past. This one was being very stubborn!
