Re: pic: Better Sprocket Assembly with AndyMark Parts
Our problems with wheels are generally a student sourced assembly oversight which inevitably causes a screw to work its way lose and then promptly hit the frame and cause all manner of havoc. Anybody have any quick solutions to this, theoretically they are using nylon lock nuts but if someone has a "student proof" solution I'm all ears.
