STAG-1

This is my first cannon. It's a 4x12" Sch40-PW PVC chamber, 4x2" ABS reducer, short section of 2" Sch40-PW PVC, 2" Sch40-42 female threaded adapter, a 4" Sch40-PW female adapter and a 4" Sch40-PW (yes, pressure rated) clean out plug. Of course I can't forget the shell made of 6" Sch40-PW pipe and end caps. After I had glued together the initial chamber I found out from Spudtech forum members that even thought I used transition glue the reducer has a high probability of separating from the chamber. So I built the shell. I machined the end plugs to have nice holes in them and proceeded to glue the shell together with the chamber. I then filled it with expanding foam in hopes of containing chamber failure. I later had to cut the huge gaping hole you see because of a design fault. 2 disposable cameras through an ignition coil had sufficient voltage to jump through wire insulation and 1" of foam, but I suspect a bubble formed around the wires leaving only some kind of gas between them. So I cut out the hole with the intent of building an ignition system into it and placing a piece of Lexan over the hole. Before this happened I decided I wanted multiple sparks, a stun gun and propane ignition, so I proceeded to build STAG2.

i like the idea of the expandable foam. seems safer.

[deathtodeer666]

You know I've never herd of a disposibe camera used as a igniter but its brillient. its powerful and basically trash.

[CS]

If you never used one why do you call them "basically trash"? They look nice if you put them in a box.

[boilingleadbath]

By "basicaly trash", I would suspect that this person ment that they arn't worth much - or something to that extent.

wow nice pieace off work... psssst did i say my line right O ur on well um hahahahaha nice pieace of crap o and y u have exposed srews in the barrel

[Shandora]

well im still trying how to rig the camera but whe i do ill post
any help search engines suck

[ƒlying$pud]

yeah very nice, it looks really safe, i rapped my guns chamber in a whole roll of duct tap(on sale for $2.00) because my parents are really safety conscious and if they saw it break i doubt they would let me make another one.

[boilingleadbath]

It has been shown that duct tape accomplishes nothing. However, if they think it will help, just smile and nod...

please tell me that was a joke, or maybe you are a pneumatic uset who never tried combustion, but if your just a noob, please have some background knowledge you know.

for the maker of this cannon, i like the foam thing, gotta do that on my next project.

[PotatoPirate]

good idea with the foam thing and oh camera thing does work good.

u have exposed srews in the barrel

he probably knows that stupid.

[SpudStuff]

i still dont get why you cut a hole in the side

[A-98]

oooo i like the fail-safe design with the expanding faom....very good i might build something like it.....maybe...i know my parents would like it

[blastopvc]

that is so flip confusing. does it shoot far. pm me if u can tell me . but it lookes realy ausom

[runningawaypyro]

i like the idea of extra safety and everything but honestly it seems like a bunch off extra work that would make this harder to adjust and change to your cannon later on. as long as your useing sch40pvc i wouldnt say its all that necisary unless your useing something like nitrocellulous for fuel...
