[PSUBS-MAILIST] gear set

[hank pronk via Personal_Submersibles]

 Thanks guys, but these people have tons of gears, but they are metal.  I am looking for plastic to keep the weight down.  I need to take a trip to the dump and look for a fax machine or something that has gears.Hank

 Hank, if what you're looking for is not an animal but has teeth nonetheless, these folks probably have it.

Hi All,I need ideas where I can find a plastic gear set for the wrist on my manipulator build.  I have the rotary actuator built and the gripper is well under way.  The way it works is, the rotary actuator shaft turns a shaft to open and close the fingers on the gripper (hand) The hand also free wheels on the same shaft so it can rotate 360 degrees continuously.  So I need a gear about 2 .5 inches in diameter and a matching gear about .5 inches or less  to drive the main gear.  The gear set will be driven by a second rotary actuator with a drive shaft enclosed in the arm member.Any leads would be great.Hank
