Rubber idler wheel rubber restoration

If you have some VCR belts around that will fit around the hard idler .
A real thin one the same width would be deal but 1 or 2 of the square
ones will work .
Stretch or place the belt-s around the idler and run a bead of superglue
around to hold it on . mount the idler in a drill and run it on
sandpaper .
If you are using square belt-s you shound sand it down in the drill
first to take some off so the finished diameter is closer .
This works for me 100%
Nice hearing the various techniques mentioned in this thread. I have
restored digital tape transport capstans by removing the deteriorated
rubber and layering back to the original diameter using multiple dips
in liquid vinyl; the capstan needs to be spun at low rpm with the shaft
horizontal until each vinyl layer has set. I did a capstan for an
HP-85 awhile ago that required quite close tolerances and this technique
worked well; the result was a bright red surface however ;-)
