Default What can I scrounge smallish metal gears out of?

I have been thinking about some possible future builds, and I think I'll need some metal gears. I've got some gears out of a car gearbox, which look good for the big stuff, but I'm wondering where to look for smallish metal gears. I would like some hints about what I can scrounge some out of.

Old TV antenna rotors are full of them, also most battery powered electric drills. I have done post on both these items, but you can do a search under "gears".---Brian

The cylindrical battery screwdrivers usually have a planetary gearbox with nice little metal gears in them.Same for batt.drills.
I second the photocopier idea,they also have lots of lovely small diameter shafting in them.Most of the gears tend to be a form of plastic though,and many are spiral or worm types.
When you say"smallish",how small are you looking for?
As a last resort,you might have to look at rc car gears.
Or,if that size is too small,how about a motorbike gearbox?Gears aplenty.
