Don't bother to make the parts yourself. Scavange them from old
copiers and laser printers. They're loaded with cams and drive
mechanisms.

I make small kinetic sculptures by buying old electric alarm clocks,
electric can openers, and other small motorized kitchen appliances at the
Goodwill, removing the motors, and mounting them into welded boxes with
long, bent rods brazed onto the motor shafts. I braze small copper figures
like animals, birds, fish, etc. onto the other end of the rods, and plug
them in, making sharks that swim in circles, for instance.

I now want to add cams, so these objects move in more complex patterns than
just around in circles. Not as complex as automatons, but leading in that
direction.

My question is where to source the cams and followers? Either as parts in
cheap appliances, or more likely, as stand alone parts ?? I would be happy
to fabricate them, but my experiments with 1/8" plexi have not been too
successful - any better ideas??

Thanx!
