Ah I see, gotchya. Well to be honest all I did was find the wire that best fit the wire size that originally came with the igniter. But this one cannon was quite the process and learning experience. I plan on taking what I learned and building from there. Thing is, I am far from an engineer and know...

Hey everyone. First, I'd like to thank the kind folks who had answered some questions for me a little while back. That being said, I have for you some pictures and a simple video of the new cannon. So what we have here is a basic combustion cannon made from ABS piping. Barrel: 3" ABS pipe at 4' long...

What I mean is, basically imagine a 2 foot long ABS pipe. Now I have two screws drilled into the pipe at an angle so that they come in to just barely meet, I don't know the gap distance but I do get a decent spark. Now just imagine where it is I have these screws screwed in on the pipe. Rather than ...

Just a BBQ grill igniter crimped to some screws. Tested it out, spark is good. Just, it's up a little ways, a bit higher than the middle, I'd say.

I just would hate to have a poopy launch lol.

How much of a difference would it make if my spark was higher in the combustion chamber then lower? If any at all. One side of me is saying that the higher it is, the less pressure from the explosion there is from the spark point to the barrel. Then the other half of me is saying regardless of where...

Hey everyone, greetings and all that fun stuff. My name is Sean, and you can call me Sean, Scourch, or Newbie, whichever ya like! That being said, I decided to make my own potato cannon. I was bored, I like things that go boom, and it's been forever since I took on a 'hands on' project. A couple day...
