Whatcha Makin'?  - 
 
Hello all. Currently I am trying to build a zoetrope, much like the one in this video, but at a larger scale. The "bucket" I buit is 24" in diameter, I'd like to have larger and more detailed frames for the zoetrope animation strips. But my snag is the crank, gears, and belt. I have no idea where to find suitable parts. I've seen some pulleys, and even some hand cranks for windows, but not really anything that I can imagine would benefit me. Any suggestions for parts to look for, or even a website to find parts?
My plan is to enter the zoetrope in an upcoming art show, an illustrate several strips that attendees could change out at their viewing leisure.
I think half my problem is that I'm an artist, and not much of a Maker as I'd like to be.

Thanks.

I've thought about that, but I prefer the hand crank method since it makes it a little more interactive and correlates with the old time appeal of the zoetrope. A thrift store record player might have to be my last resort. 
 
Take a look at http://www.sdp-si.com/ -- they have tons of spur gears. Also wikipedia Gears for terms and diagrams. You need to decide if your crank is of the side of the base (right angles to turntable or on top
You could also use (junk car) pulleys and V-belt (fan belt) which would allow some slippage for naught children that crack upser fast and then try to stop it by stoping the crank. The momentum of the spinning turntable might be enough to break teeth off a gear in that situation.
 
Cut up a child's bicycle and replace the pedal with a handle and attach the rear axle to your spinning drum. That would allow for the user to stop spinning the handle without it stopping the spinning drum.
 
James- I think the kid's bicycle idea would be perfect, and I'm fairly certain my brother or sister still have one of their kid's old bikes lying about. Great idea!
 
+Jesse Acosta glad you liked it.  A cheap grinder from harbor freight or home depot should be all you need to cut the bike down. It will still be some serious work with sparks flying so wear goggles and thick gloves and do it outside. The pedal should come off easy with just an open ended wrench and can be replaced with a nice handle.  Make sure you post pics of the process, I'd love to see it.
