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]http://www.youtube.com/watch?v=RdfpjJzyJgA[/youtube] Edit: it always jumps from tip of one to the threads closest of the other, doesn't wande...

If you had a 2.5" barrel, you could shoot tennis balls. Those don't hurt too badly when they come in at an angle. If its full on, I don't ever want to experience that again, but at an angle its not so bad because it slows down enough. This is the biggest pipe i got =/ I haven't seen any 2 1/2" in a...

Nah, duct tape balls are fine. As long as it doesn't hit someone directly, or if it has enough time to slow down it should be fine. I like to make paper sabots and put bbs or paintballs in them for a nice effect. I also mix it with flour to create a air burst effect. That is what i was going to do,...

Ill give it a try worst case ill make a ghetto wrench that i can attach to my molle gear. In the meantime im thinking of possible projectiles, besides the obvious bb's and nerf footballs. Would duct tape balls be dangerous (indirect fire) or should i go look for foam balls somewere

I'd take a photo right now but its sitting in my garage. They are roughly .2-.3mm apart and I used a file on them earlier so they are bright shiny metal. I also made the contact points with the wires bright and shiny metal and I know for a fact that it has continuity.

That's probably another problem I have, I have to wait a little to get a syringe and get my coil up and running. Won't be around for 2 weeks and I'm running out of time to build my first cannon. 60 days til I enlist. I was really hoping it woulda worked today
