Over the summer, i realized that a steady routine of eating ramen and playing Halo tends to get boring. so me and my Bros decided to make a potato gun. Check it out =)

Hahah bro i don't have venting in it. next one will have it though. but yes i do use it for filling and it speeds loading&shooting up quite a bit.

Do I see 2 spark gaps there? Thats a nice little upgrade from the average first spray and pray cannon. I also like the ball valve to speed up the fueling. Adding a fan would make more of a difference than you might think, though it looks like that would involve a hack saw.
I like to play blackjack. I'm not addicted to gambling, I'm addicted to sitting in a semi-circle.

You wouldn't need a hacksaw man. The valve is connected to a male screw on adapter so i can just unscrew it and put it in. I've working on setting up. I use starter fluid but i took the nozzle off it and put a different one on it because it makes a beter fuel/air mix. Yes, you do see two spark gaps =) The ghetto one with the screws actually works ALOT better than the actual, manufactured one. Is it ok if the Combustion chamber is made out of cellular core? its schedule fourty.
