about half of the pieces are erector. the top wheel is powered by a regular vex motor that I ran a straight shaft to one of the 60 tooth vex gears. that runs to another axle with a 60 tooth and a 12 tooth gear on it the 60 tooth runs to a 12 tooth on the shooter axle. the side shield on the shooter is quarter inch plexiglas, and the top shield is one of the flat rectangular pieces that came in the kit.
The balls are foam t-balls that I got at wal-mart, not the nerf ones budda! The top ring and the "track" is high tensile electric fence wire that I found lying around the farm. The rest of the basket is other wire about the size of coat hanger, probably a little smaller, and the elevator is the tank tread kit. it will hold about 30 balls (if I had that many)
, and shoots about a ball every half second. It will shoot the balls about 10 feet give or take, and they will go about 3 feet high
