Auto air BB machine gun

Unread postAuthor: Ianbuckwell » Thu Nov 13, 2014 11:01 pm

Came across this by accident, the designer sells the plans for it, anyone have any idea how it works, seems to use a motor and worm drive to control rrate of fire?

Main interest to me was the magazine design, it would seem to be a row of BBs in a channel which are then kept tight by what looks like elastic/ rewind mechanism (clock spring like device), rewatching video it seems to be some kind of rotational drum which you pull out the cord to tension the device, then it is permanently applying force to unwind and pull cord back keeping bbs tight, any help appreciated as like the idea of being able to have a horizontal magazine for compactness rather than a vertical!all tunbe reliant on gravity.

Thanks in advance .., Ian
