Hey everyone
this is my second combustion cannon, and it worked out great

This is what i started with about a month ago, it took a while cause im pretty busy... and im real lazy..

The initial mockup of everything

but i soonafter found there were leaks in my piping and i had to basicly reattach all the steel pipe from the first ball valve.

Fixed that though and attached the propane tank
Image

but then ran into electrical issues with my spark not consistently going into the chamber..
After all that was taken care of however..
this is what i came up with :D

Very nice cannon, looks very clean. And now, for the question on the minds of a large majority of people: What sort of ammo are you using?

A-98, he won't do that, he'll just do it with more gusto. Don't stop being lazy!

Thats crazy!

ive had my first cannon for a long ass time and never had problems with it..

yeah it sure is threaded on..
i had to get a 4-2" ABS reducer, then a 2-1.5" reducer and bought a male threaded end
it works perfectly
i blew apart some logs tonight.

I wanted to add
what if i were to switch fuels... to say the MAPP gas.?
