the problem is.. it cant be that long. It has to fit inside an empty tube i have which is 30 inches long. And it has to be 2" pipe. Is there any way to get this to work? And still get a 300' range?

well... i needed this thing done by the end of the week... so i said screw all the other designs and decided to use the grill ignitor. It works fine. Ill post up the finished product later. But theres one problem... I want to be able to shoot waterballoons out of it. I made little sabots for it and ...

Im trying to avoid using nichrome wire becuase theres no were around here to buy it. Id have to order it.

I heard you can use a violin string though... o.O

Ok ill mess around with how much fuel im using... Do you thing red hot wire will ignite fumes? or does it not get hot enough?

The rocket engine igniters are just little two wiers attatched to the positive and negative of a battery, then they have nichrome wire in between with a small amount of powder on the tip of it, so it gets red hot and ignites the powder. i was using hair spray.. that didnt work so i tried axe, that d...

So i decided to skip the whole grill ignitor idea and just use rocket engine ignitors to ignite the fumes... Is this possible? I hooked everything up, sprayed in my hairspray, and for some reason the fumes didnt ignite. So i thought maybe they were creating enough of a spark or something... So then ...

ok, well i redrilled it and put a blowgun valve in. It still "honks" So then i pulled the little plastic thing out of the rubber diaphram. Then when i fired it, all the air pressure leaked out the blowgunvalve and didnt even make it to the barrel. :( So i put the plastic part back in. And im stuck w...

wow thanks a bunch!!!!

I have used the search function for this, and i havent been able to find anything about people having a problem with there solenoids sounding like air horn. I used a Rainbird 3/4 inch inline sprinkler valve. CP-075 I modded it with a shrader valve as the release valve. (im thinking this is probly th...

yea thats what im worried about... i already blew the diafram through the barrel once... so im afraid i might do that again... and then be screwed forever.

i tried to maek this.. but the cleanout plug WILL NOT stop leaking air. I can pump it and fire it... but if you dont fire it withing a good minute... all the PSI will be gone.

I just built a puinisher valve cannon... And it works.. But it doesnt hold air for too long. It leaks terribly. I found out that all the leaks are coming from the cleanout plug's threads. I used a TON of teflon tape on it, and i've tried pipe dope. I've even used the two together... and it still lea...

Whats a popet valve??? becuase i want to make soemthing similar

O COOL! thanks man!... i think i understand it better now. im gonna go make one. lol

yea lol. It cant kill people. Well i guess it would be cool to make it so you could switch it around and put somethen more destructive in there, and then for airsoft switch back to the non lethal PAC. :D Yea thats the part i cant figure out is his whole entire wireing and everything. I dont know of ...
