love the chainsaw bike idea I had one which cruised pretty good but woulda been better set up on a 10 speed style bike, I also had a weedwacker driven vintage scooter which was ok for going around the block, and a leafblower "jet blown" skateboard which supprisingly was pretty fast and had the throttle on a cable to a hand control that you could use standing up. all project are fun projects, but whats a project without a little criticism
