Please dont bump old threads, btw I did make sevral piston valve guns. The only one I ever got around posting tho was this one: http://www.spudfiles.com/forums/velocit ... 14181.html
Maybe one day I will get around posting my other stuff.

Nice cannon! Personaly, I really think the materials you used are fine. First of all, seems people get confused when it comes to DWV parts, DWV stands for Drain, Waste and Vent this simply means that pipe that is labled DWV is suitable for these uses and almost any pipe qualifies. So yes, DWV parts ...

You might be a spudder if when you hear ultimate challenge you think: 2" fully-auto pneumatic. (im working on that )

I dont have a bb gun but my friend has a paintball gun and if i remember right he told me that there is no use to have a gauge on a paintball tank since the pressure only drops at the few lasts shots. Also, co2 tanks are filled by weight wich leads me to think that the pressure wont drop unless ther...

Well, its a co2 regulator.

This wouldn't work with air since the pressure in the tank drops unlike with co2. Right?

The reason i'm asking is because i was wondering if this would work to regulate co2. Beacause if i remember properly, in a tank, co2 pretty much stays at 800 psi until its empty...

Alright, so here is my question:

Is the pressure of co2 constant? I mean, if i have a full 12g co2 cartridge, and i empty out will the pressure in it always be at around 800 psi until its pretty much completely empty?

Thanks in advance.

i usually use a 3d animation software (3dsmax) but when im in a rush i use ms paint

Well, if you are afraid of the rubber wearing out, this should work for you.

Nice!!!
Just a little question: were can I get a regulator like that?

Ok, thanks a lot for all the input but i think i will go with this one:
