jsr i once again require assistance lol


ok so im not going to buy a qev because i did research and basically a brad nailer is a piston valve and i have a nailer that i am not using. its just like this but gray and made by true power(got it for 10$ new) http://menards.com/main/tools-hardware/ ... c-9076.htm

anyways im having a problem i tried doing a few test shots and not all of the air gets released at once how do i fix this? i saw an old thread and jsr posted an animation. From what i could tell i just remove the "striker thing" i already removed the pointed peice on it but i left the thing it was attached to inside. so i assume i should remove that,fit my barrel and epoxy it in place correct? also do you think tis can handle 400 psi? or will it blow up in my hand?

ahh my stupidity got the best of me :x i should have searched better.
anyway.... so i assume its safe to use at 200 psi max? assuming it cracks at 250psi? so now that i kno that id rather get the qev ill buy one right now but if i do so that leaves me enough for a 300 psi shock pump instead of a 400psi pump..... thanks alot for the help!
