1. remove original tire from metal hub of idler wheel.

2. Chuck a piece of 1-1/2" PVC pipe in the lathe and use a boring bar to
cut the inside diameter to the same as the outside of the metal disc.

3. Glue the PVC to the metal disc with Weldwood contact adhesive.

4. Measure original thickness of drive tire and face both sides of the
PVC (centered to the disc).

5. Do a finish cut on the circumference to make sure the PVC sleeve is
concentric to the idler shaft.

6. Take a piece of 0.103" square Buna-N O-Ring stock and cut to length
to be just a bit short so it's a slightly stretch fit to the PVC.

7. Glue the ends of the cord together. Having an O-Ring cutting and
gluing fixture makes this really easy.

8. Glue the completed "tire" to the outside of the PVC sleeve.

9. Using a grinder on the tool post, grind the tire concentric to the
idler shaft.

10. Install back in phonograph.
