Lathe and tire machine opinions

I'm really, really interested in the lathe. That is a downer with the newer cars rotors not generally being turnable. But does make sense, as nowadays they manufacture stuff to be disposable after limited use. But with the number of A-body cars we part out, I could start stockpiling drums to turn if they have enough material left on them. The entire setup in the pic is for the $500, that would be awesome to be able to turn drums, rotors and flywheels. I think it's probably a no-brainer, I am going to have to get the lot of equipment. Better take my trailer up there and get the lathes and tire machine. I figure the lathe will get the vast majority of its use for just our projects, but that's okay with me.

They can be turned, you just have to pay close attention to how thick they are and what the minimum spec is. Generally, that spec is stamped or cast into the drum or rotor. Sometimes it's not and sometimes it's not legible. Generally though, unless a customer has been REALLY hard on brakes, they can usually be turned on the first brake job. Make sure you use a rotor micrometer like this https://www.amazon.com/Anytime-Tool...ocphy=9011223&hvtargid=pla-491357565573&psc=1 because you need to be able to put the points into the lowest areas of the rotor. A micrometer with flat anvils is not accurate at all. Here's one that actually measures both correctly.
