I need to start advertising that Ill turn rotors. Ain't nothing to it, took me about 10 minutes a rotor.
Not really but if nobody does it. I'm sure there is a market for it. Like for classic cars and whatnot. I did mine because they'd have to be ordered from Japan and they were 139 before shipping. Shipping is about $75, so I just decided to learn about turning rotors.
Some folks will pay extra for "lighting" and balancing. Which really amounts to drilling holes or milling slots and making sure it's still balanced afterwards.
