This wheel has been reconditioned by being soaked for 7 days in DOT 3 brake fluid to reconstitute the rubber.  The edges on the wheel are relatively free of pitting.  The rubber is soft and pliable.  I did not get to test the wheel because the motor went bad shortly after I reinstalled it after treatment.

I acquired a nice Lab 80 Mk2 with every intention of bringing it back to life through cleaning and oiling the mechanism.  Unfortunately, after some tinkering the motor went up in smoke.  So, I am selling some of its parts off in hopes that they will be useful to Garrard fans with more technical abilities than myself.
