11mm Automatic Ball Bearing QEV gun

[Cosmic Muffin]

Hey guys this is my build log on my new 11mm Automatic Ball Bearing QEV gun. the plans were posted in the discussion forum here > http://www.spudfiles.com/forums/full-au ... 23329.html still a way to go. needs the bolt made for the blow forward bolt design, im going to construct that with epoxy and a large bolt. the magazine tube runs paralell to the barrel. and its going to have a spring feeding the ball bearings to the bolt mech. at the moment im still waiting to finish casting the whole trigger setup. i had to modify the gun by epoxying new 1/4in threads over the existing because none of my parts would fit -.-

ive since added a new chamber which is about 3 times the size shown here. although i havent used the full automatic functionality yet. i have connected a small chamber to the hose and pumped it up till the valve pops. it sounds mad. similar to a .22. cant wait to get it working fully.



just the other side of the setup.
with that nice squishy insulation tube.


the business bits


hope you like (:

UPDATE (:



layed out on the perspex sheet im in the process of cutting for the body. as you can see the designe has changed for the time being. it has a "cloud" chamber (the pvc) instead of the blow forward bolt idea i had, it rips up though. i wouldnt want to get shot by it thats for sure. sounds like a mini gun at 140psi ><
