Wow very nice, we could help you with the piston problem if it still hasn't been fixed.

Love the custom ammo too, it looks great.

The bullets look very nice.

They will tumble in the air because the barrel is not rifled but if you put a feathered tail on them it would keep them facing forwards after firing.

How do you make the second cannon do multiple shots?

By the way, when you said "escape", the word "leak" would be better.

I'm not complaining, your english is better than my french :wink:

Dude, those bullets are sweet... Do you have a lathe? On the topic of the accuracy of them, you could skipp the fletching and such and instead have a light tail on it's back. Just a suggestion.
I too am curious as to how you get multiple shots on a piston valve. Also, does the piston valve one breach load?

There are in fact 2 chambers of compression: a big Coca-Cola bottle (1,5l), in the which I put the compressed air, and an aluminium tube around the cannon.
I fill first the Bottle, than I open the bottle valve, and close it...


I shall like to make slits on my bullets, but the diamond disc of my dremel is broken ...:s

I made this bullet with a drill with column which st too slow (2580 t/min maximum...)

I have videos with the coca cola pneumatic canon...I will post it later...

Nice work Kiwi- very nice.
