oh and should i decrease the tank to 2inch?

In my experience I get upwards of 15 shots per cylinder but I use only 65 psi usually.

is that regulated? is the regulator expensive? And what demensions was your cannon?

It was not regulated and my cannon can be found here http://www.spudfiles.com/forums/files/portable_209.jpg

Can someone explain how you attach a blowgun handle to a sprnkler valve instead of a solenoid? I dont want battery charges, and propane in the same area O.O!

Im making this tomorrow so helpppppppp me please!

Hey for your cannon what release valave did you use, its very confusing looking!

http://www.spudfiles.com/spud_wiki/inde ... dification This should help out.

i am still at loss as to how you remove the giant solenoid and somehow screw in the blow gun valve. Where? I mean th pilot vlave of course, can someone show me a youtube video?

You don't have to remove the solenoid. This is good video http://www.youtube.com/watch?v=9PKVyzV0aGU

Is there anything non flammable besides co2 and just air that i could use thats bottled? I think il go with propane, but will the propane pressure be good enough to launch a nerf rocket a good distance for airsoft? Like 200 feet?

Nitrogen is a alternative but it can get pricey.

i don't know if you mean air from a bike pump or hpa as in just air, but you could use hpa it works really well but you will have to buy a expensive reg( usually around $80) and tank(usually around $20) set-up, it will not cost you as much as nitrogen thats for sure and if your filling a large chamber it might be more economical than propane also. i know propane looks good @ $4 a bottle but the fact is if your filling a good sized chamber it will run out fast

My Hpa setup was $20 for the regulator and $60 for the tank.That is without shipping though.

um, of i do the propane setup il be using a disposable propane adaptor, connected to the chamber! So its ok if i directly connect it? It wont overpressurize the pvc right? Qill the shots be consistent and should i use a 3in or 2 in chamber?

If i buy this stuff id hope iot would work

As long as you keep an eye on the gauge over pressurization should not be a problem and your grammar is driving me nuts! :violent1:

tnaks for the help, but with the sprinkler mod do i have to have the hose? Is there a way to put the pilot valave directly on the sprinkler valve top where the barb was?

When he screws in the barb in the video does he actually "screw it in" or just jam up the hole between the barb and plastic?

With irishers cannon i assume there is a sprinkler valve ther somewhere, by the front of the barrel right?
