Bookmarked! Thank you. I can't believe some of the prices. How's the quality of the goods you have purchased? Seems like for those prices it would be cheap chinese pot-metal crap.It's from these guys - http://www.surpluscenter.com/
I've bought tons of things from those guys over the years, good company to deal with.
The stuff I've gotten has been name brand stuff, same as you would get at Graingers or McMaster-Carr. They just buy out surplus stock from companies. They started out selling armed services stuff, mostly airforce surplus.Bookmarked! Thank you. I can't believe some of the prices. How's the quality of the goods you have purchased?

The gears are there, but the output is inside the one side of it. It is a (I think) 4mm square socket. Originally these drove a flexible shaft, like a speedometer cable.Thanks for the replies.
At Shortbus: Does that motor include the drive gear? or do I have to buy a drive gear together with the shaft?
I think wiper motors are slower. Around 45 RPM on high speed. At least GM is that speed. One time I made a couple of fishing down riggers for a guy out of wiper motors, pulled up a 5 pound ball with no problem.How about a wiper motor from a car? Remove the plastic gear and you should find the worm gear in their close to your specs.
The online or catalog prices are scary. But when you go into the store, they are usually 40 - 60% cheaper. Think they do it that way to help out contractors. When a home owner gets a bill, and sees a parts charge, then goes to Grainger online, they see how much things cost.I've used surplus center myself. Good company.
Have you looked at granger gearmotor prices?
They seem 4 times what I remember.
Armature speed is way higher. More in the thousands of RPM. There's a pretty high gear reduction in a wiper, that's what gives them the torque.Are you referring to gear speed or armature speed? Pretty sure armature speed is more in the range of what he was looking for. Gear speed much slower and yes they provide lots of torque.
