lol I've seen their work.. some of them are true artisans.. though some would argue it's form over function...

anyway it's good that someone posted that... there is always something you can learn from others

Looks pretty cool, may be a spring load ball valve

Wait....using tampons as ammo? Why haven't any of us thought of that before???? :D :D :D
I can read a little bit of french, but not that well. He says he's taken the gun up to 25 bar with co2, and It has a range of 100-200 meters with a sabaut if shot a 45 degree angle. he says something about a sear previously, but I don't understand that part.

thats a great setup, same idea as most ball valve triggers with a nicely made trigger, sear and spring ..

There are a lot of really nice guns through the french forum , might be spending a bit of time having a look through there .... if only i could speak french :lol:

that's a nice setup, the arc that guides cable gives the spring gives consistent leverage, it's a great design and it's really well made, but I think I'll just stick with piston valves

I am looking to trigger my ball valve as the pilot valve for the piston.

I have noticed different power for slow opening and I want a constant pilot action.

My cannon requires less than a 45* angle to fire, not a full 90* opening.

The problem is that the ball valve is currently the trigger and it must be pulled towards the rear.

I would like to integrate the handle and a spring sear.

Pull a little, and she fires.

Any ideas?

I've got an idea for my new Co-Ax that is the simplest spring loading system i could think of i drew up a diagram of Sketchup for you its pretty sloppy though :oops:
Its basically a spring inside a tee, it is stretched down to a nail in socket that locks and opens easily, then thats attached to a BV pilot

I hope this helps out, if its too vague ask questions, or i can scan a good drawing
