If someone wants to send me one or two plotters with bad drive gears, I'd be
willing to have a go at repairing them. My technique involves repairing the
damage with Araldite (epoxy adhesive - sets rock hard) and then putting a
small (#10) staple in across the damaged section. The staple is heated with
either a soldering iron or a small "night light" candle (as used for
aromatherapy burners) and is then pushed in across the damaged section of
the gear. Two are fitted across each cracked section, one on each side. Like
I said, if someone wants to send me a dead plotter, I'll have a go at fixing
it. I'd be tempted to take a few 10ths of a mm off the inside of the hole
for the shaft that the gear fits onto. If they're cracking, the shaft is
probably too big for the hole. Enlarging the hole very slightly should
reduce the pressure a bit and hopefully make the gear last a few more years
that it would have done if it were not modified.

I know that frustration only too well...

I'll give you $5 or so for the remaining five if you can find them. To be
distributed among anyone on the classiccmp list for my cost only.
Alternatively, can someone get the RS part number and annoy the salesdroids
at their local store with a "Can you get this in for me" request? Living in
the UK makes it quite difficult to get stuff that Radioshack are/were
selling.
Later.
