machine shop?

Great advice, starting small.
Its even difficult to find a place that turns drums and rotors anymore. A simple brake lathe.
(I used to operate the blue Ammco lathe with my eyes closed, remember the chatter belts?)
I guess most people replace drums and rotors since the steel isn't what it used to be.

Haven't turned a drum or a rotor since 2001ish? Didn't make sense when even then rotors were available for $20 each and drums were becoming a thing of the distant past. Of course I remember the chatter belts--wrap um tight and even then on big bus drums they'd still sing their song's. J.Rob
