Belt Sander Racer Confession #2: I Swapped the Pulleys

At the last second (in the pits no less) I wound-up switching the large pulley for a smaller one. The big one shown here was very fast, but it caused the sander to accelerate very slowly. If the race lasted 10 seconds or more this wouldn't be a problem, but in the end we broke the 3 second barrier, so I guess we made the correct choice. I left the photo of the large pulley on the blog because it was the only one I had at the time, plus that whole misdirection thing.
