The four shot toilet brush gun did not work in full auto (power drill mode). The rotation destabilized the "arrows" too much and they tended to entangle, even return... way dangerous. But I invested too much time into the weapon, and the toilet brushes are just too much fun. So I converted the weapon to a manual repeater. You unlock the "drum" by pressing the lever to the front, then you turn the whole thing 90 degrees. The new position automatically locks in place. Then you pull the "spoon" trigger and the shot falls. This way, you can fire four "rounds" very quickly - and safe. A lot of fun. Another TV team will come tomorrow, we will film the episode together.
