well my dual chamber sprinker cannon doesnt really shoot. it kinda just lets air out when you depressureize the sprinkler valves. you can watch the pressure gauge and see it drop pressure. it lets of a bit of a burst but nothin to justify 40 dollars per vavle to fire it with. my cannon has 2 3 inch ...

what should i use as a vavle to pressurize the cannon. with my other phuenmatic i just use a blower chuck cause it is a dishpan. this one i have a shreder vavle in it from a truck tire but it seems to have a much harder time getttin air in. i can only get to 20 psi after 5 -10 sec whereas i woul dbe...

i have two 1 inch sprinkler vavles attached to my spudgun. one for each chamber. it seems when i de pressurize the valves it will let a burst of air but then after the main burst there is a trickle of air coming out after. it leaves some pressure in the chamber which leaks out slowly. is that normal...

thanks i wasnt sure if you kept the ratio of dry ice to water the same if it would be predictable enought to use for a gun. just one of those thoughts.

it was a thought awhile ago of mine to use dry ice to pressurize the chamber of a copper gun. dry ice here is cheap and always available to me. using the same amount of dry ice per amount of water you could get the same pressure each time right? of course i would do ALOT of testing to find the press...

yea i wouldnt think of going over 120 i start to get nervious at 90.but yea just for a buffer zone i would like 200 psi. the ace here doesnt sell by the foot. but they do have some stuff like 10 feet for 5 dollras so i think i will go with that. sorry bout the triple post i didnt relieze there was a...

yea i was gonna hook both of the hoses into one release valve of some sort. the town i live in doesnt really have a good hardware store. we have an ace but its pretty small a nd does offer what i want so it might take another week or so to get all the fittings and hose. the elbow does have a factor ...

well i currently have 3 phuematic ( by far my favorite) and 2 combustion. the 2 combustions are just general ones nothing special. i have 2 dishpan phuenmatics one with pressure gauge one without ( first attempt without a gauge). both fire a potato 300 + yards at 80 psi ish. i also have one almost d...

i was wondering when reassebling the sprinkler valves should i leave in the springs or remove them? i dont see what good they would do besides closing the valve when the pressure is low enought that the springs decompress. would you even notice the loss of this small amout of pressure? also should i...

well the hybrid gun is deff the most powerful but to complex and costly for someone like me to build so i will stick to the middle and say phuenmatic wins for praticality. my 3'x3" chamber 6'x1.5" barrel dishpan gun can put a spud 200-300 yards in a hurry.

well my friends i are thinking about building a dual chamber (3" by 3') with a 1.5" barrel using two 1" sprikler valves. both of the valves would empty into the end cap of a 3" to 1.5 " reducer in seperate piece of pvc as to double the the airflow. as of right now we have a basic dishpan valve spud ...
