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

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

not to bad at all.

hey how do those pumps go im considering buying one for a mini im making.

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

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)?

i have a pump similar and i cant get it up past 50 psi unless thats one of those co2 ones.

im guessing AA batteries...

yea. ur right. i duno what i was thinking. D batteries are 1 1/4 inches.

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.

Yep I shoot AA batterys.......It takes about 30 pumps untill I can't pump anymore...

Beautiful. Simpe and effective. Any chance of going near 100 psi?

Posted: **Fri Apr 20, 2007 8:22 pm**

any chance of 300psi? im sure it would hold but the barrel may fail around there

Posted: **Fri Apr 20, 2007 8:52 pm**

yea. AA bateries at 300 psi

i am going to see what the feet per second would be

Posted: **Fri Apr 20, 2007 9:01 pm**

wooo...i just shot a battery though that blue bucket from 2m

Posted: **Fri Apr 20, 2007 9:01 pm**

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
