thats a good idea to make molds with short sections of rifled pvc but what the heck is pycrete. i couldn't find out how to rifle slugs but i did think about that but i couldn't think of how u could do it without a piece of rifled pvc. and to spudblaster i had already tooken of the end peice but i added a popsicle stick under the handle to make the blowgun open more.oh i have a question how would a rifled slug spin? would it be from the air going down the slits in the slug pushing it causing it to spin?

What is pycrete? It’s in the Wiki.
And on rifled slugs, yes, it’s like the fins on an arrow, as the air flows over the spirals it puts a spin on it.

i shortend the hose and just test fired it at 60psi and it did not shoot

now what.

Try a ball valve. Do you have the solonoid hole filled(Im guessing yes)

yeah it is filled with epoxy

ill try to get a ball valve tomorrow.

what size ball valve should I get my fittings are for 1/4" air hose. i still dont get why the valves wont open because my gun is just like joels double chamber tennis ball gun and he has more air hose than i do but he uses 2 3/4" orbit watermaster valves and i use 2 1" lawn genie valves because that is all the home depot had.

Unscrew/remove the hose form the valve put your finger over the hole and fill the cannon up till you can’t hold it, about 15-20psi, then remove your finger if the thing still doesn’t open then the valve is screwed.

ok ill try that right now

my valves aren't screwed luckily And i am so glad to see my gun let some air out of the barrel. I think I should shorten my hose even more even though i have a total hose length on my gun of 11" if that doesnt work then i am going to put a ball valve on maybe.

Hmm…my LAW has a hose about 2feet long and a blow gun, the thing works great…
Ok before you cut anything put the blowgun directly on the valve, pressurize it and see if it’ll fire then, if not your blowgun is screwed. It should work…

Yeah, and I would have never thought of that finger thing .

i don't have fittings to put my blow gun directly on my valve

Blue tooth what do you mean you never thought that finger thing what are you talking about?


I was reading how to mod the valve on spud wiki and i pulled my blow gun apart and I don't know which hole it is talking about to enlarge the one permanently forged in the handle or the on on the piston thing that screws out i don't know which. and is it ok to do both modifications or will that make it not work

ok ive modified my blowgun by making the holes bigger on the piston and all the other holes on it but i still did not get my gun to fire, then i unepoxied the brass elboes on the top of my lawn genie sprinkler valves and turned them to a 90 instead of a 45 degree angle to make the air pathway as short as possible, and then i pumped my gun up with my finger on the hole on the brass tee and then let go at 20 psi and it did not work niether did it work when i put the blow gun on so now i think i have to get two 1/4" ball valves and open them at the same time. but i did fire my gun i stuck an empty butane can in the barrel with some wadding behind it and only pumped it to like 10 psi mand let my fingers off the elbows in the 2 lawn genies and the butane can flew out and noked this trash can over in my house and then hit the stove and put a massive dent in the can. so i think the two ball valves will work i just will have to open them at the same time. since my valves are retarded and wont open with all the hose even though now i only have have total of 5-1/4". so if anyone knows how i can get these to work tell me. i think if i buy two new orbit 1" watermasters then my gun might work but for know i am going two buy two 1/4" ball valves and open them at the same time. so know i dont know what to do now i wish my valves would open when the little hose i have i dont know if i should by two orbitwater masters or just use my gun with the ball valeves that im buying tomorrow ohh well.

Doesn't Joels gun use two Supra's accuated by two sprinkler valves? That would be why he has no problem. If you can join the ball valve handles together, like a old time eletric switch/fire alarm handle, so you can pull them at the same time.
