Ok thanks.

said message was too short, so I added this.

I just got all the parts for my first pneumatic gun. I bought a 1/8" NPT Tank Valve to put the air into my chamber. Would it be better and safer to drill through 1 or 2 layers of PVC to thread it in. The total threaded length is about 7mm long. Since it is threaded it would be safe to just drill a s...

I like the first one, now I gotta figure out the correct dimensions. I want to have a 3/4" barrel specifically for paint balls. I was kinda thinking of changing mine to be like that and have a 2 inch chamber on the bottom. I'll make sure to have a parts list

Hmm 5 foot barrel, that's pretty long. would there be any way I would be able to keep the barrel a little shorter than that, add the 2 inch tank, and still get good performance?

Maybe I could have a 2" diameter chamber connected to the bottom T on the stock instead of the stock having to serve as the chamber. I have herd about people blocking off the T so air doesn't get through, how would one go about doing this, not sure what it is called. Searched it but nothing came up

Yes I messed up on the picture but forgot to go back and edit it. Still trying to figure all this stuff out, it's more time consuming than I thought :P I'm still a little unclear, instead of threading it through one layer, are you saying I should have the schrader valve go through the side of the en...

Wow... I don't know what to say... At least you have some vision out of it. Thank goodness for no torn retinas.

Well I've been wanting to build a pneumatic for a long time and finally found a forum with good information. I do have a few questions about my design though. On the bottom with the schrader valve, should i put it on the end like I have or through 2 layers of pvc on the side? I have herd of people d...

Yes I have already bought it and modded it, I ran out of money at first so I had to buy all of the parts at different times

Alright, I'll plan on doing that. Thank you

I'm going to be using a modded 3/4 inch sprinkler valve and I was wondering: If I wanted to have interchangeable barrels, would it be better to have one adapter permanently in the valve and then the barrel have the other adapter on it or just have one on each barrel and screw it in when I want to sh...

Thank yall very much. I went out and launched it about 40-50 times and it was a blast. Thanks for yalls help

I usually put the end on the ground when i shoot and just shoot it up in the air. A friend of mine tried to shoot it like an rpg on one that he made and it blew off, it wasn't good

Didn't know the difference back then between the different types of pvc, I made this for a school project. Sure enough, the fittings are dwv.. but they should be fine for a combustion?

I posted this in the combustion section but now realized this is for the construction materials, sorry for that. I made a combustion spud gun about 6 months ago, before I found this site. I just now realized that it says nsf-pw AND nsf-dwv on the combustion chamber. It seems to be thicker than regul...
