ok, so i should add a fan propane meter and im considering an electric igniter if im going to do one of these ''upgrades' which one will give me the highest increase in performance? or should i just build a new gun if that would just give me better peformance at the same price as all these upgrades ...

well i have a regular old combustion and i use hairspray as a propellant but i want to make it nicer. now i cant spend alot of money because im ordering some stuff but any suggestions are appreciated. i want to adda propane meter but i dont know how much propane to use also can the meter be made usi...

i am. im up in plainfield

oh ok then i thought they were plastic. where is the qev at mcmaster i dont see it

ok i went to lowes today and bought everything besides a barrel and qev those will be ordered shortly but by plastic qev i thought that the qev in the semi auto valve post was plastic i also thought it cant hold 400 psi? EDIT: will this work? because im going to buy it tommorow if i can use it http:...

ok this is going to be finished by next weekend but last time i asked everyone if i should get a plastic qev they said it might bursat at 400 psi? im probably going to buy a metal one thanks for the help

ok thanks! lol before i get a qev should i buy one or make one? i was theinking about making a 1/4in qev and ill be using a 6in chamber and where can i find a barrel

hmm ill be extremely satified if i can shoot through 1/2 in pine i heard that takes some force you think i would be able to shoot through that?

ok thanks alot! would it be possible for me to just make a 3/4in qev or 1/4 in qev?
also .25 seem a bit small for my desires however can it shoot through 1/4 in plywood? and would it be easier to find a barrel? If yes id rather use .25s than anything else

what ammo do you reccomend? i dont know where to get an unrifled barrel

ok thanks! im considering .357 pellets or .50, problem is i have to order all of my ammo because i cant buy .50 or 357 at any stores around me i dont know of any that carry them. If i were to use .50 as my ammo would a 1/2 in copper tube work as a barrel? also if i have a bigger air chamber will it ...

wwell i have everything planned out but i have on problem what material do i use to make the front bendy peice(forgot the name) i have no clue what to use for it. any ideas? thanks

i want to penetrate umm idk 1/4 in ply wood but still have power once it exits the other side(not much just speed to fly another 20 ft or more) so basically i want to shoot through 1/4 in plywood at 50 ft+ .My goal for this project is to make something that looks like a sniper and is accurate but ha...

ya but atm i dont have a qev and im not good at making pistons(im extremely bad at it) i was planning on a sprinkler valve because im not sure how to make a good piston for a qev/sprinkler valve. what size barrel would give me more power and accuracy than my current 1/2 in one? any tips on making pi...
