This is just a little gun I came up with this week to provide a more portable combustion cannon for me to use. Decided to build it after wanting another "small" gun. Here's a few pictures.

very nice cannon, what so you shoot out of it mostly and about how far?

i like your sig btw

Thats a cool cannon but to my standards i wouldn't clasify it as small. How far does it shoot?

EDIT: to late for the how far does it shoot . Any damage pics?

All I've been shooting mostly are blanks and D-cells. It's dark so I can't tell the range/damage.

You can't see where your shooting yet your shooting d-cells?

Yup. I think you don't realize I live WAY the hell in the middle of nowhere. Mostly I've just been shooting into a stand of oak and underbrush right next to our house.

How long does it take you to get to the closest store? ( i bet those pizza delivery guys hate you lol )

nice gun i would defently want to see some damage pics

Nope. It's just as easy for me to flip it on when I start and off when I'm done.

Very nice, but you should build a sparkstrip for it. My bbq ignitor can easily handle 3 good-sized sparks, and the preformance went WAY up. It went from boom to BOOM

I personally don't really bother with dual ignition anymore. I find that one gap at the back of the chamber works great for me. My first two serious cannons had dual ignition, and they're not anymore powerful than the LB and now the Junior. I still think that pressure rise is equal across the entire chamber, regardless of the position of the flame front(s).

Wait, aren't blanks kind of dangerous? I thought the force of the explosion had to be transfered to the ammunition...
