This is a video I had from the construction of my K'nex Ferris Wheel: http://www.youtube.com/watch?v=AB7mGH...

This video was made when I was still trying to figure out the best method of powering the wheel, as it was quite obvious that a single 9v K'nex motor would not do the trick. I decided to fasten a 1300 RPM power drill to the drive axel, which worked quite well (although I had to hold the trigger down when i wanted to run it). Just for fun, I brought the drill up to full speed to see what would happen, and the outer rim of the wheel accelerated to a top speed of nearly 20 MPH (quite probably a world record of its own for K'nex ferris wheel speed). Needless to say I did not use the power drill as the final power source.
