Double QEV 1"1/4 cannon

[Brice]

Hi,
I'm a new poster on spudfiles, to introduce myself a little bit : i'm from France( excuse all the mistakes, my English is far from perfect,) I'm also member of the french "patator forum"
I've been lurking on spudfiles for a long time, now i decide to post my latest cannon, made out of 1"1/4 galvanised pipe (the biggest diameter I was able to find, i would have prefered 2") with 2 QEVs : the 1"1"4 is homemade and a 3/8 indu one, piloted by a schrader valve.
the cannon is quite powerful at 20bar, with a 26mm barrel 1m long, using all kind of stuff as projectiles.






I'm going to use a rod to trigger the valve and make a bullpup out of the gun, because it's a bit bulky

Bienvenue au Spudfiles!

Tres beau travaille, that should be one hech of a powerhouse when finished I especially love your trigger system, schrader valve piloting for the win!

Cool lookin cannon...looks powerful. What is your piston made out of??

Compared to french cannons it's powerful, but compared to spudfiles' standards it's probably not so much
the piston is currently made out of bolt, nuts, steel washers and a piece of plastic tubing, but my brother has access to machining facilities and could perhaps make a better one for me.
