I recently got upset with a geared hub motor so much i just gutted it and used the magnets to pick up nails in my driveway. Upon doing so i removed everything planetary gears stators clutch all of it. i was fed up. This evening i was sitting scratching my head about how i was going to put brakes on my schwinn occ chopper when looking at the rotor and looking at the hub and getting nowhere with the materials i had available to me. I needed brakes now! And cheap! It occured to me i had seen this similar bolt pattern before. Very similar in fact on the inside gear of the planetary gear assembly from my geared hub motor. If this has been mentioned I apologize as I'm new here. But i couldnt help but post something somewhere if only for my own reference of my discovery. Any ideas or criticizm welcome.
