Sadly, I did not do a WIP while making it and I don't have any video of it spinning. I know some video is out there somewhere since at least 3 people have filmed it. But I don't have any of the footage. I think Lucas may have some from the Straight Outta Comicon shoot.
It's really an easy build. Uh...as long as you don't try using a cordless drill motor. Too many RPMs and torque. Barrels just fly apart and go everywhere
. Cheap airsoft motors and batteries work great. Mine is a bit off center on the motor drive shaft so it wobbles in the housing some until it gets up to speed. The ammo chute was harder to make than the gun itself, to be honest.
