    Also check www.surplusshed.com. They have a wide assortment of gears in your price range. Also maybe consider getting plastic pulleys for timing belts, and reshape the cogs to correct gear tooth form.

    Maybe form your own gears?





    Just press the steel gear against the spinning plastic blank and friction will soften the plastic enough to for the teeth.

    Try McMaster Carr, they carry a good selection of plastic gears. Bob.

    Last year's printers, from the recycle center, neighbor's trash or yard sale.

    Not sure how much force the "small plastic" gears will need to stand up to but since they are "small" and "plastic" I do have one suggestion: LEGO. LEGO Technic has a lot of small plastic gear parts including some crown gears. Another "toy" that may have useable parts: Kinex.

    Small Plastic Gears

    I have a project which requires small plastic bevel or crown gears. I'm looking for ones in the 1.25" - 2" (30mm - 50mm) diameter range. I've done Google searches, eBay searches, which have yielded gears which are in 1/2"- 3/4" diameter range or ones which can be special orders for $50 each. I'd like to find ones which are cheap ($1) range and would appreciate if anyone who would happen to know of a place where I could get them. Thanks.
