Copper Mini Combustion

Miniature guns are novelty custom, unique, and sometime downright crude! Common construction materials often include pill bottles or pens. Show us your work!

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.
Novacastrian: How about use whatever the heck you can get your hands on?

...I'm sorry, but that made my year.

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.
I wonder how much deeper the ocean would be without sponges.
Right now I'm having amnesia and deja vu at the same time. I think I've forgotten this before.

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.

Yeah!
An ultra-clean, shiny copper mini hybrid!

That would be really really cool.
