ok but knowing me ill stuff it up somehow

yeah im just a little special and does it get any easier than that???

I know that there will be people here who will call me an absolute tit and tell me to look at the how-to section but so far I have and I hasn't really helped me.

Can someone please explain in great detail how to make a 1/2 inch self-closing piston valve?

I'm completely lost.

could you write instructions on how to make one because no getting it

Im thinking of scaling it up to the size of a rifle.

is anyone else thinking M1 Garand.

I am

im having 2 main tanks one will be high pressure running along the sides and a low pressure tank after being filled from the high pressure tank is what is being used to actualy fire the round. im firing small darts which i am going to put into foam sabots.

I am using a tee reloading breech. I will be firing 2cm long flechettes from this pistol.

thanks for all the interest in my concept. SEAKING9006 - I like a bit of a struggle and I can't buy an airsoft gun that is why I am buying one and I have 2 friends helping me. Cosmic Muffin - thanks for the help with the solenoid and the piston I have a 1 inch valve at the moment on my carbine which...

if I use an electronic trigger I will probably need to add a high voltage capacitor to deliver a strong enough charge to the soleniod in one go pluss I will have to drill a bigger pilot hole in the valve also where do you buy a small solenoid? im guessing bunnings

my idea is to make a repeating piston pistol where the piston between firing and returning to its normal position it reloads the pistol. my problem is I know there are piston valve making how to's but I have trouble understanding them plus i need to know how to make a piston in half inch pipe. all h...

i think I will by the QEV from the website and I'm thinking about using a piece of 1/2 inch copper pipe as a barrel.
@SPOOK I would prefer to keep just two tanks like i wanted to earlier because I want to keep my gun compact and 4 tanks would take up too much room

they only have one king of QEV in the site click the link to see it I'm not sure if it is the right type though beacuse i havent seen any QEV like it on spudfiles

your correct in your understanding. the problem is with a QEV is I don't know where to get one and i dont want to import

my dad is a plumber and all his friends are tradies so pretty much anything

a combustion would make the balloon pop because it will burn a hole in the rubber. you could put a wooden plate between the combustion chamber and the balloon or sabot the balloon
