I judged this contest at our Regional a couple of years ago and saw a really clever braking system. The front axle was a threaded rod containing a fairly loose nut that was bottom weighted so it wouldn't turn. The nut was originally at one end of the rod and as the axle turned, the nut moved across the rod and eventually jammed against the wheel. Of course the pitch of the threads had to be selected carefully to get the right number of turns before stopping. -- ------------------------------------------------------------------------------- Van E.
