Source of small nylon gears?

[Roger Mills]

My Fellowes shredder has decided to shred one of its reduction gears
instead of the paper!

Fellowes don't carry spares for 'small' (domestic) shredders -
presumably because the labour costs to fit spare parts would exceed the
cost of a new shredder.

But those economics don't apply to DIY repairs - and I could get it
going again cheaply if I could find a suitable gear.

It's the sort which has two integral coaxial gear wheels. The big one
(about 51mm OD) has 39 smallish teeth and the small one (about 18mm OD)
has - or rather HAD - 7 largish teeth.

A picture of what is left of the gear can be seen at
http://www.mills37.plus.com/Shredded_gear.JPG

I don't know whether Fellowes make their own gears, or buy in standard
components. My gear carries the number 550307 - but Googling for that
didn't yield anything useful.

I would need either a replacement for the whole thing, or just the
7-tooth gear - in which case I would need to machine the residue of the
broken one from the larger gear and attach the new one to it in some way.

Anyone know of a source of this sort of thing?

TIA.

If you dont find what you need, epoxy is an option to recreate the 2nd
gearwheel. Not a quick fix though.

Epoxy? How do you do that?

If you have a "good" one you can try casting epoxy in a mould, e.g. RTV
silicone or paraffin wax (you may have trouble with bubbles unless you
warm the epoxy, which won't then work with wax.
