ok then the pressure will make it go forward and fire a ball right?
Is this design better than the otter one?
/edit:
What pressure do you recommend? (it dont't have to be lethal

Sadly I do, and I suspect it will happen in this case.thespeedycicada wrote:it might work but i think the air will just slowly leak out without cycling the valve.
jsr has alot of experience with this phenomenon.

ok, tnx.
So what do you think of my 2th design?

It has a much better chance of working, because you're cutting off the air supply as the bolt moves forward. It's similar in principle to the idea posted here.stereohead wrote:So what do you think of my 2nd design?

Hey tnx, that's nice.
How big does the chamber have to be?
And what pressure do i need for just shooting 'not lethal paintballs' ?

at least the same volume as your barrelHow big does the chamber have to be?
you should be fine with 50-75 psiAnd what pressure do i need for just shooting 'not lethal paintballs' ?

Look likes the semi-auto design i posted a week ago : http://www.spudfiles.com/forums/album_s ... d,361.html
It worked for me, i used a modded sprinkler valve, so it was 2 or 3 seconds before the valve would actuate correcly and the chamber would fill up at about 75 psi. The only way to make a semi-auto mecanism to work faster would be to only use a smal part of the air contained in the chamber.
