If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.
1980 550 Brake Rotor

It doesn't look badly grooved at all. I'd just clean it up with some fine sandpaper on an orbital sander (which puts friction-inducing swirls on the rotor) or even by hand, or with a Scotchbrite pad. Get any dirt off it by wiping it down with some Brakleen first.
To really refinish it, it has to be ground down with a stone. Regular disk cutting tools are made for cast-iron disks and will chatter on the hard steel of a motoroycle disk. There is a place in Michigan that will do it for about $45, plus shipping both ways. I had a local machine shop do one for me, but they charged $75 and a week later it's grooved again so it wasn't worth the expense.

Ed, I'm changing over to Salty Monk's twinpot upgrade on my brakes so I'm going to throw the older 550 rotors on and go from there. I already have one from him but need another.
