Ok, thanks, in fact this think (my pop-off) was an air cylinder before, its for that reason it is very big. :? I am gone to try with a hole at the bottom , thanks dude :) LOL the farting machine!! :) , (with an audio amplificator it could be hard) And thanks for your links all your pop_off are great...

Hello ,hell!! i have some problems with a pop-off valve i tried to make. Usualy i ask people of my country's website ,patator.forum but we dont manage to find the solution. First of all the pop- off is working , with a ball valve a litle opened but without the qev. You can see that in my video: http...

So better pictures for you !
Soon i will put the scope on, it will have a terrible look!!

hello , i have found some good piece of alu to make a stock and something to hide the plumbery stuff. And i made an other verin more resistant to pressure, i can go to 10 bars easyly. http://i24.servimg.com/u/f24/14/84/11/71/p9190010.jpg http://i24.servimg.com/u/f24/14/84/11/71/p9190011.jpg sory for...

I would like to find a fridge compressor, i am thinking of it everydays.
but its a little hard to find in france.
I will post other movies and damage etc....

3 bar, and the bb go as far as a 1 joule bb gun . I think i can go up to 5bars with my crapy piston but i dont have compressor, i only got a shock pump which is very howfull to pump my extinguisher!

Take this gun as a prototype , i will ameliorate it!

Hello, i made a semi auto bb gun, Jules 56 has inspired me with his system : http://patator.frbb.net/systemes-de-tir-f40/semi-auto-a-verin-t8351.htm We can make great things using the pressure of the chamber instead of trying to make a gbb which is much more complicated. http://www.youtube.com/watch...

hey everybody, the chamber i used is that thing: http://www.genix.fr/images/images_prod/BD/CHP_203____.jpg I don't know how its called in english but its just a chamber with a classical bike valve, without non return valve . i don't think its only a french stuff. i dont know exactly is fonction but ...

Yes i love steampunk style , like the game bioshock or mad max...

I waned to say that the escape of the air is biger , so more powerfull.

haha, yes its hard to pump!!
I have an other version with more efficient "blow out"
this gun is more powerfull, but it shots one time.

yo, thanks , the power is not great, but i said that the shots were at less than 100 psi.
<haha yes its a nightmare to pump until 200psi.
Before, i used to shot screws like that, but without qev, and they did not stay right. But now with the qev they fly like arows!!!

Thanks, I can up to 200 psi with this pump: http://www.velo-leblanc.com/image.php?file=./images/produits/G-1916.gif&w=342&type=jpeg And the video , i shot at less than 100 psi there. Sory i dont manage to put directly the video. http://www.youtube.com/watch?v=svJT19_lHpM I have an other one which co...

i shot at 200 psi max, i will try to make a video , i go!

ok yes , but in 6mm its the only i hown. for the 8mm bareel the lenht seem to be good,?
