Worked some more on the weapon today. Added a nice front handle, Moorhammer style. Banded all four forks up.
I quickly encountered a huge problem: Return to senders and misfirings!
Those returners are dangerous. I mean seriously dangerous. One hit the door right next to my head... two inches to the right and I'd be in trouble now.
I don't really know what is going on - what I found out is that it works as long as you turn really slow. The fast spinning action of the battery drill is probably too much, destabilizes the "bolts" in flight.
I attached thin rubber bands to at least avoid the return to senders - this works fine. But there is still the issue of the tumbling bolts. About half of them do that. It must have something to do with the rotation - no problems at all if I turn by hand and push the bands up one at a time.
If all else fails, I will convert this baby to manual repeating action.
But it does look cool!
