here is my frist go a a cannon made from all the stuff i found lying around. build cost $0

its a little heavy but for the price its fine! it uses a piston valve and so far has only been fired at 100psi .

Very nice for a first effort! Chamber size is a little overkill but nothing wrong with MOAR POWER damage pics/videos?

hey chamber to barrel raito is only 4:1 24 Litres chamber to 6 litres in barrel no vids yet always forget as its so much fun but will try and get some tomorrow

Any pictures of the piston and sealing face set up? Nice work. That tennis ball looks like a tight fit, was that picture for size reference?

your first? made entirely from spare parts?

Paint those two tanks industrial yellow and I would expect Mike and Sully to show up.

That thing is a friggen beast! Nice job on the welding. Whats the piston made of?? Can we get a peek inside?? Nice first!!

hey sorry for the slow replys been one of those weeks!
The piston is made out of so plastic bar that was at work with some o rings and rubber as the sealing face.

And yes this is my frist cannon it did have a ball valve on it to i made the piston for it.

here is the only vid i have of it

Looks like fire extinguishers.

some weird looking FE's... Thought they were beer kegs at first glance

cans to put the milk of cows!

Wow, haven't seen that until now. Dunno how I missed it. Looks excellent! I like the size of it. I suppose SB15 should be happy that a large bore has popped up, even if its not a hybrid or combustion.
