nice to see you BTB
as usual , i don't understand your drawing , but still exiting

shame
i prefer hammer valve than qev+ slide valve
qev+ slide valve may easier to make
but definitely hammer valve is more powerful

did you finish your gun , waza8u?

noway
it can gets 10000psi because you can't compress liquid
compress air is much more complicate

thanks ijahman
i read your post in patator.frbb too
now i definitely must make something like that
and ,have you ever made a 6mm combustion before?
because i can't buy paint ball here
and 12mm ball bearings are to heavy

Damn you, JSR, damn you

agree
i like that trash box
and salt gun too

if i have a co2 bottle , slide vavlve , qev ... it 's easy like Lego
hardest part is buy or make those stuff

can you draw a diagram. or somthing
way air in , air out
i can't imagine all

is that a homemade piston valve?
i try to get multishot with my homemade piston valve like that before
it's suck
because the vlave's sensitive depend on your piston quality , want semi auto the piston must perfectly fit, moving easily, and good sealing face, of course
so , buy a qev , a blowgun ...

you should make a stirpump
it's not very hard to make and it can reach 50-60bar easy , and much more faster than shock pump

pressure you use ?
use GGDT

in 200psi , the ...

Pour moi les 2 meilleurs sont Spudfiles et patator.frbb.net en France.
