Beautiful looking gun Spike. I love how clean this gun looks. I've seen the video of your piston valve before, but I don't understand french :( .

Anyway, job well done and welcome to Spudfiles :D

The only thing that worries me is the parts he uses. I doubt I'll be able to get that tee with a male porting on the side. Eh... I'm working on a linear valve at the moment anyway.

What pressures do you run this gun at spike?

wow, you did an amazing job. i would love to see more of your creations.

is the copper barrel new? Because I don't see any oil stains or corrosion on it at all.

10/10 - clean, shiny, and beastly as hell :wink:

Love it. Nice. and clean. Would be awesome if you could color the tank copper color.

Dont know if you saw it, but there was a thread recently regarding your valve, its in the pneumatic canon discussion, near the bottom of the page.

BTW, your english isnt bad at all, better then some americans :wink:

soon I will try to put a bottle which holds the high pressure, because I have build a high pressure pump , full metal which goes up has 430 psi (30 bars)
there are a problem with the blowgun which go only to 150 psi!

here it is, it is very out of copper, with brass connections.
it is a system of piston O ring, and the system not return functions with a ball and a spring.
