Not too much science, just some magnetism and a couple physics laws. The magnetic field just tries to stop the disc rotation.
Fixed the wobble, larger hinge pin with a shim between the hinges. Welder works super for a power supply although it starts at about 20 amps on the lowest setting. But so far its working, when I spin the disc up to about 2000 rpm with an electric motor, it takes about 2 minutes for the disc to slow to a stop. Spin them back up, turn on the welder stops in 10-15 seconds. still trying to get the instruments to read properly but it seems to be working as planned. Have not had much time to work on it in the past couple weeks but its is progressing .
