http://www.chiefdelphi.com/forums/pi...10&quiet=quiet thats a pic of our wheels, version 1.0 that is, then we created spikes to cover the entire wheel, anyone who watched the early practice rounds on curie at nationals knows how well, the judges loved those wheels : ) ,that was version 2.0, then after the judges kicked us off the feild after 30 seconds of our first practice round, we realised we need to change them, or be forced to resort back to version 1.0, what we came up with was to place strips of neopreme in between each row of spikes, and hold it in place by pushing the spikes closed.
heres a pic of one row of spikes that we cut off because they were too big around the wheel
there are about...100 rows of these 1/4 inch spikes so approximately, 4200 total on both wheels. as you can see, each has 3 teeth, don't you wish you has as much fun as we did making those?? i'll find a nice picture of the finished product (version 2.2) and post it here
