I have made a pneumatic pvc air canon design, pretty simple...the usual 2 in. pvc and ball valve...over all pretty simple. I need help making a round for the canon that will get a decent range at 100psi and somehow airburst or do something to explode on impact or in the air to create an explosive airsoft bazooka effect. I have looked up airburst cartridges but it doesnt look like you put them in your cannon but rather you just shoot something out of them? Anyway...I need help making shells. Any help would be greatly appreciated!!!!

If you mean actually blowing up (fire) then that is against the forum rules.

If you mean one that crumples and leaves a nice dust cloud, something filled with flour might work or try dried out plaster casts.

no what im going for is something that would hold bbs and then in mid air or on imapact release them to recreate fragmentation for a wider spread but still with at leat a 100 ft range. (non-explosive no fire please)

Alright, you could try a paper cartridge filled with BB's, or put a sabot down the barrel and pour BB's on top of it, but that would be more like a shotgun. Be creative, find something that fits down the barrel and fill it up with BBs.

Something tied to a rip cord, (kite string/fishing line).

like this?

that one seems to work fine, and the rip cord can be as long as you want it to be.

can you please post a more detailed instructional video on how to make one like that? It has to fit into 2in of pvc

If you want more detail, there's a thread somewhere in Pneumatic discussion about it's development.

And it's about time somebody linked to it!

BTW, instructions on how I made the shell are early in the firing video. I made mine out of a bottle, but just paper ought to do it, too.

paper rips really easy at 100 psi and please link someone!

well then, add masking tape. or dont make it out of paper. this is really a quite simple concept.

Go to orientaltradingcompany.com and get some holiday spirit.

If used an an indirect fire, easter eggs filled with airsoft pellets or water and airsoft pellets work great. They have strong durability on the vertical, so they can be launched, but horrible horizontal, so they break easily.

Don't get the eggs with the little tab things.

And don't worry, I've shot myself with easter eggs many times and done lots of calculations with them. Getting hit by one filled with water has close to the same momentum as a paintball over a larger surface area.

I know this is a little off topic, but you could take a ziplock bag, pour flower in it and wrap with rubber bands. this would create a white phosphourous kind of effect when it lands.

Is the idea of starting with a basic concept, using your head, and figuring out how to do it yourself really THAT abhorent to you?

I had an idea for something like this awile back. You make a bdc like davidvainis with a needle barely touching the burst disk. Then on impact the needle penetrates the burst disk and airsoft bbs fly everyware.

Google next time its actually easier to do then asking for help.
