Here is my lateist combustion. It is propane injected, chamber fan, and electric sparker from my grill.

It has 2 ignition points, one at the front and 1 at the back.

The chamber is 8'' of Sch40 PVC and then like 14'' of 3'' Sch40PVC. I just made it out of the things I had around. Then there is a 2'' Sch80 union on it, it was supposed to be my hybrid until my friend DWV fittings on it. And then it has 2 90* DWV elbows to a 1.5'' barrel.

I made the support out of some 1/2'' ply and the zip tied it and taped it on there. It does have propane injection, but in the pics it is off because I was changing everything around. Before the tank was mounted to the underside of the barrel and then connected to the meter by a T with a PSIG on it.

The chamber fan is in the back,and the propane is injected into the back, and then the fan pushes it to the front, it works really well. For the fan I just had it attached to my drill battery because I didn't make a box for it.

Overall it works really well, but it is SUPER loud, hence the name gunshot. When I shot it it sounded like a 10gauge shotgun. And then 2 police cars went down my street looking for my I guess lol. It is powerfull too. I prob wont shoot it anymore because of the loudness. I might sell it if someone wants to buy it. But if you do it will not come with the sparker or the contacts.

And I didn't make it to look really good, it was jsut made with things that I had laying around my garage, I did have to get a few things. And the paint was done by my g/f.

Here are some pics, enjoy-


Looking in the back at the chamber fan.

The front looking at the union and were the end of the meter is.

View of the back, and the metal plate on the wood is were the sparker mounts to.

The eclectic sparker from my grill.

And there are wires all over because I did have a project box and I didnt feel like making one.

Nice throw together WoW. One down fall -- those little red solderless connectors allways corrode and fail! I hate them things more trouble then they are worth. Use "shrink tube" and twist the wires together. It will last longer!!!
P.S. -- Nobody sucks more then Jenna Jameson, ecept maby Brania Banks.

Dam, I wired my whole go kart with those lol.

And that is prob true lol

Them friggen things left me sitting in the middle of York County Pa. one night a hour from home, i told my friend not to use them, guess what, he did anyway. Luckly i knew rite where he putt them and it was a easy fix, eletric fuel pump mounted on the frame back at the gas tank, (after market pump).

"sucks more then Jenna Jameson" lol

thats a pretty nice cannon i have a suggestion for the next time you paint pvc, use krylon fusion its a little expensive but it gives an plastic a nice even coat. you could be the worst most un even spray painter ever and it would still come out nice

looks prity nice. i like it 8)

Its painted like that purplusly(bad sp). It looks really good like that with the blue and faded white. You have to see it in person to get a good look at it.

Pretty darn good! But it needs a project box. Then let all the land know that yo have put a project box on it!

I was going to say, that's an interesting use of the union. Since you ditched the idea of doing a hybrid, perhaps you could use that chamber with different combustion cannons.
