You must be using a one-way roller clutch so that the rubber band can over run the van door motor. Very clever.
  • Lets the elastic take over when it needs to.
  • Doesn't require an elaborate catch.
  • Rapid firing without complex sequencing issues.
  • Allows the "follow through" of the arm to partially wind the arm for the next toss.
  • van door motor starts rewind automatically when the arm slows down
Beautiful!

I had my doubts about the feasability of making a rapid fire catapult.

But, you ave done a great job, one that I think has a chance to compete with the pitching machine solutions.

Well done.
