I have noticed a small screw on the idler wheel, i wondered if this had
worked loose and was slipping ocassionally on the shaft. The rubber
band is new. thanks -b.

The only other remedy i can think of is to replace the motor, I don't
suppose there is too many of those kicking around, unles someone is
breaking one up.

The central pin in the middle seems to spin freely without any
resistance, as does the idler wheel, but surely it has to be that
idler, there is no other moving parts connected to the platter.

The only other problem i could think of would be the power to the motor
fluctuating, is there a component controlling the amount of power
directed to the motor?

After looking at it again, i can not be sure the idler is wobbling or
if it is a trick of the eye watching the holes throught the platter.
When the rubber band is off and the platter stationary, it would apear
to spin without wobble, but then again it may only happen when it is
under load, if i press my finger against it whilst the idler is
spinning it would seem to be ok, but then i'm not sure whether i would
detect such slight changes in speed.

Any more advise out there other than binnit? I am not ready to give up
on it yet.
