Using mustang rotors for 4.5" bc
I machined the mustang rotors using a rotary table on a vertical mill. I couldn't get the setup rigid enough to get a satisfactory result in reducing the diameter but I was able to get the hub dimensions machined. I then set up the rotors on my old Burke horizontal mill and got the diameter turned down. It was a ton of work getting an arbor fabricated and finding a cutter that worked well but it got done.
