Why did you put a ball valve behind the QEV on picture 3 and 4? ( at the exhaust side)

Thats more likely a safety. There would be now point in having a QEV if you still had to open that ball valve every time to actually fire. More of a "lets make sure i don't get shot in the face while loading kinda deal". It also probably has the benefit of keeping starch from gumming up the QEV.

the ballvalve behind the QEV is the pilot, using a BV give much more poer over a blowgun. the one infron of the QEV is a saftey

Er... It's machine head (davidian) and rage against the machine (renegades of funk)experament-u2 wrote:it looks good

edit: actually pistol grip pump from the same album would have been more appropriate
