SpudFiles

This is the second cannon that i have built but it wasn't intended to be a gun. It was suposed to be a horn. I have a 1''barrel that i got from schmanman but i have no pics of it yet. I'll post them as soon as i take them. It consits of a 2''chamber and a 3/4'' Rain Bird sprinkler valve. Its trigger is just a light switch and i made a wood handle for it. It is filled by a tire valve and uses 3, 9-volt batteries to open the valve.

well it could do well as a gun but i guess it suits your needs. I see some DWV parts but you should be fine if you keep the pressure low.

the highest it has been was 120psi.

Don't ever take it up to 120 psi again, thats when most sprinkler valves start bursting.

mount a trumpet horn on it!

I've been to (get this, I dont care) 155 psi with a sprinkler valve repeadly, and no such thing ever happened!

its a bunch of s***, If you ask me.

in fact, that is really the only pressure it is ever used at.

people need to start trying things themselves (to a certain extent) instead of quoting what the last person said.

I'm not saying to go build a cellular core, dvw gun with a sprinkler valve, and then to hook it up to a unregulated 20oz co2 tank, I'm just saying to try things yourself.

I mean, 30 psi is not gonna make a huge difference.

50 or 60 would, though.

Schmanan - I've built a DWV pneumatic before. It was my first spudgun, in fact. And I would DEFINITELY not recommend DWV parts for pneumatic guns to anybody else.

Mark, I have a feeling that you completely missed his point.

Is that a PW bell reducer?
