Sorry, french guys. Hey petitlu, C'est normal que la pression baisse d'une bar quand tu ouvre ton metre à gaz sur la chambre de combustion, son volume est plus grand, donc l'augmentation du volume en ouvrant ta valve cause une répartition de l'air sous pression deja contenu dedans. Essaies de faire ...

Your piston might be dirty. You might have a small pec or something like this on the sealing face. Try to open the QEV and see if the rubber piston is all clean. I've had a similar problem on my new airsoft coaxial. Rubber was deformed and allowed air to pass in the barrel. OR: you ball valve can be...

I personnaly know how to open a beer with pretty much anything from a sheet of paper, a lighter, a wood log, a table corner .... haha sometimes it's useful
Nevertheless, it's fair to say that the design of the opener in the first post is great!

+1 for inonickname... Some partys i've done with friend tend to prove you should stay away from pretty much anything actually...

Yes , yes please avoid hitting france!!!

Absolutely amazing, how I would love to be there and test it with you guys!!
The report is makes is certainly congratulating!!!

I envy you D_Hall !! Mr Carmack is a genius! I've been following Armadillo aerospace's videos for a long time, and played every game he (and others) wrote as IdSoftware! Wanting to work as a propulsion systems engineer is partially due to Mr Carmack. However, I do believe that in a relatively close ...

If you have acces to some regulators, you can set them so for each 'X' of air that is injected, a certain amount of gas is injected aswell. Preset the gas injection regulator prior to use, according to your chamber volume.

I went all the way up to "shipping methods" and "no shippment options are available to selected country"

You could try to sabot a .177" pellet or BB in a .22" sabot. That's what i've done for the 757 m/s 0.24g airsoft BB. it was powered by a ridiculously large chamber (in comparison with the caliber) and a 1 meter long 8mm barrel. I'm so dissapointed ultimatespudgun don't ship in france, i'm desperatel...

You need one thing that will be much more important than a spring behind a shorter piston. You need to think by yourself, i'm kinda upset it seems we didn't even have the conversation a few weeks back. Everything you are asking right now was answered several times in your previous topic, let alone e...

Petitlu!!!!! Ou est-ce que t'as trouvé ta QEV industrielle??? Ca fait des années que j'en cherche une! Je m'étais résolu à fabriquer une QEV maison qui fonctionne a merveille mais... bon, l'appel de la simplicité! For non French people: Petit lu!! Where did you get that industrial QEV? i've been loo...

Stop talking already! Build something!

Yep, had a little ghetto cloud BBMG that i hooked up to a 6L water + additives FE. (The one i destroyed with my hybrid a few years later). I couldn't pump it to 300 psi, so i would just run it unregulated at somewhere around 120-180 psi. It was a great thing, and the 200 BB's a second were a beast. ...

The joys of hybrids
It wouldn't be the same without that deep and "round" 'POOM + echos' now would it?
Their power can be a little frightening aswell...
Nice build ^^
