What can I scrounge smallish metal gears out of?

[Kaleb]

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.

found a printer on the side of the road the other day, full of gears, rods and springs not even counting the rollers and old VCR'S, Lathe Nut

Old circular saws have nice bearings and gears.
