This is the biggest pipe i got =/ I haven't seen any 2 1/2" in any local stores I wish i could shoot tennis ball's, i got a ton of them and there easy to reuse

Yeah, its hard to find... Just try expanding your spark gap a bit, that should work, and if it doesn't its your fuel mixture.

Yep i adjusted the gap [youtube][/youtube]

Edit: it always jumps from tip of one to the threads closest of the other, doesn't wander all over the place so i guess thats a plus

Ok, I would say try it with fuel now. It looks like it should work, so I don't see why not.

Still can't try it out until next sunday. I'm going to airport for italy in 17 minutes

warhead052 · Thu Apr 19, 2012 1:44 pm

Alright then, have fun in italy. I will see if I can think of any other possible problems.

Sitting in a terminal sucks. Thinking about my untested cannon is going to bother me the whole ride

I would be more worried about enlisting... 'Specially for the marines....

Well just got back, so i'm going to test it out sometime tomorrow. Work or not, ill post a video of my process so i can get some results.

So i tested it out, and i got a few launches. very hard for it to ignite. I was using carb cleaner, because i got no luck with propane. Launched a paper cup about 20'... :mumum:
Heres how i prepared to shoot. I used the compressed air can to start the mixing processes, and then i used a ghetto cardboard fan.

And this is what i got at first.

And then out of no were i got this one big launch.

It was a rolled up piece of cardboard, with a round piece with hot glue for weight on the bottom taped for a tighter fit.[/youtube]

I know the spray and pray part probably has a lot to do with not firing, but is this all the power I can expect. It is also extremely quiet.

Psh, I have no choice. Born in Turkey, have to serve at 18. Plus I would be less worried about testing something then going and getting my ass shot.

Back on topic, nice to see that it worked! And its no surprise the paper cup only went 20'. Try filling it with airsoft bb's and see how far it flies.

I filled the cup with hotglue. It reduced distance by a lot. I'm going to try to find a way to put a chamber fan in somewhere

Have you tried just a sabot buck shot?
