ok thanks i will give i a try, i really want some kind of pre-charged catrige that i could load though. i while also make one for airsoft if that changes anything. EDIT: i have decided to make it 12" long, also i want to use the co2 i am using for the paintball gun, for the grenade launcher with som...

i want it to be pretty short , and the highest psi i can go to is 125. i was thinking burst disk was the way to go but if anybody has any suggestions i would appreciate it.

thanks , i figured it out, im just gonna make a snapvalve like btb's

i am trying to use a safety valve with a qev to achieve full auto but when the pressure reaches the point to make the safety valve piolet it just leaks and dosent "pop-off". i you need pictures i can put them up, thank you for your help.

how far can it shoot ?

We already had this discussion I thought?? My 1 1/2 inch pulse valve put a mauler valve and supah valve to shame. I posted ggdt results in another thread. Also a 3 inch tee can only handle 120 to 125 psi safely where a aluminum valve can withstand much higher. I put a golf ball through both sides o...

thanks for all of the information guys, but which one would you say is the most cost effective ?

i was looking for one, how much is it and where could i get one, do you think there is a good chance of me finding one in a scrap yard ?

is this good ?

i am about to build a large air cannon that will shoot thinks like tennis balls and golf balls and i was wondering what is the best valve for it, any ideas ?

i did but it was to weak it wouldn't push the bbs up , so im gonna get thicker gauge wire and try it out

i made a mag that uses the air from the check valve that is used to pilot the qev , i haven't tested it yet , but im pretty sceptical about it, it think it will get about 2 or 3 rounds out and then stop working, i will post pictures of it later

yah i will problably just do that, but i am having trouble finding the right compression spring, any idea where to get one ?

yah i was thinking about doing a whined up airsoft mag because i already have the spring and im on a short budget cause i just spent it on my new air cannon, and are there any cheaper airsoft mags i could mod ?

i need to make a high capacity magazine for my automatic air cannon, i will be shooting .5 caliber slingshot ammo, any help is greatly appreciated

ok thank you i just started using ggdt
