triggered burstdisk paintball cannon
Posted: Tue Jun 02, 2009 3:35 pm
so while i was waiting for some parts PLAUGE and my QEV+popoff and i was bored and that the hardware store so i desided to spend a little cash and make a little ball valve paintball plinker. this cost me like $25 (i already had the 3/4in ball valve) so i got what i paid for. but while at the hardware store again yesterday and saw some pvc unions. so after $15 and about 20minutes(that 20minuts included the trip to the store) i had a extremly powerful cannon now.
for a barrel i have 48inches of 1/2in sdr 13.5 and a chamber of 1 1/2in by 24in. to hold the burstdisks i have 2 sch80 3/4inch threaded and a 1/4inch ball valve to vent the piolet area
i use blue painters tape as a burst disk and on the chamber side burstdisk i also but in a layer of wax paper so add just a little strength it.
if fill the piolet area to 50psi and the rest of the gun to 80psi, this gives me a fire every time (almost. sometimes the tape is a little stronger and takes more pressure)
now the pics!
hole gun
chamber and valve section
and the burst disk holder section
i know this is my first completed gun but i am calling it my third because it was started last
BTW at 80 psi it is too powerfull and bursts paintballs in the barrel. i am currently looking for some stronger ammo to shoot so if you have any suggestions they would be appeciated. and yes i have thought of potatoes
damage pics and a vid will come after i freeze some paintballs or find better ammo
UPGRADE:
yes i did upgrade this after only having it for 1 day.
i redid the burstdisk section to fix some leaks, make it more comfortable to hold, and made it safer
