Well I made this more then a week ago, but been to lazy to post it....

Pressure chamber: 1 foot of 3/4'' galvanized steel pipe
valve: 1/2'' ballvalve
Barrel: 60cm of 1/2'' poly pipe
I don't know what pressure i pump it up to but im guessing maybe 65 to 80psi...
I used to have 1/2'' gavenized steel barrel and it was really rough and crap.....but when I got some pipe 1/2 poly pipe for my future piston gun, I was shocked to fined out that 1/2'' threads go into a 1/2'' ballvalve :shock:
batterys fit perfect...good barrel=good performance :)
yesterday I helped my friend make one pretty much exactly the same but i think he put a wire stock on it.....he should be posting it soon

yea. all you need now is an air compressor so you can take it to 150 psi and up. but that is clean simple and by the look of that bucket effective :lol: just wondering. how long does it take you to pump up that chamber with the bike pump?, and how did you get the bike valve to stay in , is it threaded or did you glue it in? last question it what kind of batteries do you shoot (i am guessing D but i could be wrong)?

super spuder for your question "how long does it take you to pump up that chamber with the bike pump?" it takes about 4-5 pumps with a good bike pump, I usually do about 5 pumps on mine. By the way im his friend with the other ballvalve gun like this one if you were wondering why I know this.

well that program is messed up. it tells me it will go 4 feet per second :( and i double and triple checked everything. so if anyone else has a way of telling how fast that will shoot at 300 psi let me know :)
