I've been playing with clay for a bit and have some ideas for some steampunk pieces. Steampunk - Wikipedia, the free encyclopedia

i was wondering if anyone had or knew where i could find small cogs, gears or springs (or any tiny interesting piece of metal...)?
i would be happy to take them off of your hands, and happy to be pointed in the direction, basically i have no idea where to start and would love any info


TIA
