Ebay :3 But be forewarned, it takes 15-30 days sometimes to get them if you order from China. But the selection and price is really great. If you'd rather, Blue Moon Beads sells a few types of keys in small quantities for about 5$ a bag (here in NY) at the craft store.
Gears you can get online, I got mine @ Ebay.
And make sure you have super glue, trays for them to dry, and acetone to take the superglue off of your fingers (nail polish remover). And Patience. hah.
super glue ... thank goodness it's nothing more exotic. huh, i'll swing by some local bead shops and see if they've got the keys. I was thinking of just getting some old broken clocks from thrift/antique shops and dissecting them for the gears!
No prob. Dissecting clocks is harder work than it looks, I forewarn you. Also, while you're at the antique shop get skeleton keys. :3 More authentic, I'm sure.
For the gears, they come with pins in them for tiny little things you need a lot of strength and need to put forth a lot of effort to get the pins out of the gears, and sometimes gears can break if you don't distribute the effort properly. Hold it in your other hand securely with flat nose pliers, and then in your main hand use chain nose pliers to pull the pin out, upwards, never sideways.
thank you for all this advice; I suspect it will save me a lot of time. I'd have never guessed there would be all these little difficulties!
I want to figure out a way to combine the gear thing with wire wrapping and do something entirely new. Plus I figure, being as my life goal is to build an airship, technically the people who would be most interested would be the same folks who buy jewelry with gears in it, so I should hop in the gear train hehe.
heh yeah :3 It'll be fun. Aggrivating at times, alas...fun! I enjoy it, along with my wire wrapping. But then again, the piece I did both clockwork and wire turned out really elegant more than steampunk.
