Hello,
This is my first cannon posted. It is a copper mini combustion with 1/4" diameter barrel. Good for shooting q-tips around the house using map gas as a propellant.

| Exceptional. I normally think of copper cannons as "small", but this one has caused a little re-evaluation of what sizes are possible. |

Amazing!
Beautiful clean mini, probably the best I've seen.
The C:B ratio looks out of wack though, I think it would be better with a larger chamber. |

The C:B ratio is not optimal. However, I wanted to keep the two tubes the same diameter and close in length to minimize the size.
Thank you all, for the positive feedback. |

| I used the ceramic insulated electrode that came with the igniter. It is housed in the rear 1/4" connecting tube and was locked in place by filling the tube with J-B Weld. |

Wow. Yeah I gotta give that a 10/10. Awesome.
I bet you could make it into a hybrid if you wanted to. |

That would be really really cool. |
