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.

An ultra-clean, shiny copper mini hybrid!

That would be really really cool.
