The shaft of the motor for my van de graff generator is too short to put tape on it. On the web page, you said something about using a plastic pulley with a hole in it that you could use. Where can I get one of these?

Just make one out of a bit of plastic.
Or ask at a hobby store that sells motors.

I had previously taken apart an old remote control car. I used the gears from that to drive a separate driveshaft (made from a smoothed down nail) so I wouldnt have to worry about the rubber band slipping off. I'm not sure if my motor can handle driving the gear and the rubberband at the same time...How can I tell if my machine is generating static without inserting all the wires? I've also made makeshift hotglue edges on the glass fuse to prevent the rubber band from flying off and am using an asparagus (vegetable rubber band) band b/c it is much wider...How much difference does it make with the wide vs the narrow rubberbands? How fast must the motor spin to generate as much static as the tv?

my vdg was a success, but tell me whether the brushes should touch the rubber band or not.
