Quad Cannon anti-aircraft style

[x9851338]

I found this video on youtube. Interesting design but it appears to have a few problems. I think some practice with the air mixture or maybe a metered propane system would work good.

Does anyone know anything more about this cannon/similar cannons?

Uh... looks kinda cool but its not really something I'd stay interested in.

I've never seen 4 combustions rigged like that before though.

kinda stupid. I mean, it is kind of novel, but it is very unwieldy, and weird looking, and probably not that powerful.

on top of that, it is probobly a bi**h to reload.

Mmm... auto spudguns, multibarrel spudguns and in this case multi cannons are all excessive and not worth it.

Its all just trying to mimic military weaponry for the wrong reasons.

You could make an auto spudgun but whats the point? You're shooting potato at inanimate objects and it'll soon lose its fun once you find yourself reloading the bugger with a sack of potatos yet again.

People will say it looks cool but will go back to making single shot designs because a really powerful single shot is a lot less effort all round.

and can do more damage.

just get a big barrel, and shoot buckshot if you want multiple shots.

I like shooting 4-5 apples at the same time.
