My SX-111 has developed a tuning problem, mechanical in nature.

The main tuning shaft is coupled to the tuning cap and slide rule dial
via a compression/friction type clutch arrangement.  In other words, it has
a large phenolic disk that is sandwiched between two smaller phenolic disks
(at the very edge of the larger disk) with adjustable spring compression to
increase the friction between the larger and smaller disks.

These smaller disks are on the very edge of the larger disk so that a
rotation of the main tuning knob will rotate the two smaller disks which in
turn, will rotate the larger disk through friction.

Its more complicated to explain than it actually is.  Anyway, this
arrangement in my SX-111 slips.  I have tightened the compression nut quite
a bit and do not want to go any further.  Anyone with a good fix on this to
increase the friction between these 3 disks to eliminate the slippage?
