Welcome Boyntonstu. Liked your elevator. Do the wheels mark up the walls? Have been thinking on building one for a while but thought about using a pulley and counter weight system that could either be done by hand or with a small dc motor. The winch seems like a cheap and cheerful way to do it too.

However I got a bigger giggle out of the shot gun...too much fun but not enough physics. Thanks for Sharing! ~PJ
