home made nerf or air gun , for under $12 bucks!

Well , after looking at a certain instructable , i found a very interesting one about an air release valve ( very nice video i must say) but sadly i never has 1 mm tubing nor the spring or the little rubber stoppers, but then it hit me when i was watering my plants (yes.. plants nothing more) if water had to stop then so did air! the best part is that it already has a trigger, so this is how i made the my gun

Items needed:
Hose nozzle (the blue thing on the picture)
almost 2 foot tube, use anything that would work like copper tube,schedule 40 PVC,Broom stick handle, sawed (what i use surprisingly hard and light , perfect for me! )
2 lt soda bottle never had any soda bottles around (i dont drink pop, it kills your bones!!!) so i used 500 ml water bottle, good enough but it pops around 50 psi
tape skewers
rubber water stopper for hoses
drill with a bit no larger than an inflating needle
and some hot glue or silicone, but it takes too long

Mandatory things:
Eye protection
hands that do not touch glue gun nozzle to see if its hot enough ( AKA wear gloves)
Make sure your not an idiot , if you are have some one with you thats not

WARNING:
Do not shoot nail at and biological living organism (translation : anything the breathes moves and eats EG: birds, humans, squirrels, ground hogs and rabbits )
Nails are extremely dangerous when fling out the barrel remember longer the barrel ( not not insane long) faster and longer it goes (thank you velocity!!! i right ,right?) , i never made a safety , once pumped it can shoot, once you press the trigger

but if u put a needle into the bottle the air will escape right?

Cool! I'd use a pop bottle instead though... Made for much more pressure.

how far does it shoot?

Wait, to fire I pull the water release nozzle and i use a bike pump to put air in through the needle before loading and firing?
billybenj says: Apr 25, 2010. 12:20 PM

i got a couple questions about the needle, did u just use one that pumps up balls? and did you glue the needle into the waterbottle, or is it attatched to the pump and u just push it in when you pump it?

yeah i glued the needle onto it but it doesnt do a good airtight fit , after like 4-10 shots it will come loose still trying to find a way of making it better (had an idea to use a bicycle tube valve) but yeah you just put the needle in the bottle glue it and pump it works for me

k thx, i got it working better now. I think must've not let the glue sit for long enough, but now its working good.

I love this design... I need a cheap nerf gun for a party coming up in a few weeks and this is going to be great... I am currently working on modifying your loading so that it is easier to load a nerf bullet in (that way you don't have to mussel load)... but ill try to get some picks up once it is done...

great job!!!! :D

hi i feel yu

 You should reinforce your bottle. This will allow you to use much higher PSI's and make it less dangerous to use(practically no risk of explosions). Just wrap the entire bottle in 3-5 layers of duct/gorilla tape. I know some of the other people commenting on this project have said to do this, but they said that it would only stop shrapnel from flying from the bottle. What they might not realize is that it will also reinforce the bottle. The more tape you put on the bottle, the stronger it will be.

twenglish1 in reply to Ghost WolfJan 4, 2009. 2:24 PM
no i know from first hand experiences
Phoghat in reply to twenglish1May 12, 2009. 5:34 PM
If you tape the bottle with duct tap, from top to bottom, and the bottle explodes, it will prevent shrapnel.
Ghost Wolf in reply to twenglish1Jan 4, 2009. 6:55 PM
it blew up on you?What psi was it or how many pumps?
twenglish1 in reply to Ghost WolfJan 4, 2009. 7:54 PM
i don't remember it was like almost 1000 pumps though, LOL
Ghost Wolf in reply to twenglish1Jan 5, 2009. 3:17 PM

twenglish1 in reply to Ghost WolfJan 5, 2009. 6:08 PM
yah i was fine it just hurt like sh*t and yah i think he is, i talk in proper english and type it on the computer
nutsandbolts_64 in reply to twenglish1Feb 19, 2010. 2:38 AM
if you type proper english on the computer then you shouldn't use the word with the asterisk up there in the first place. but then it really hurt so you were forced to say it. why were you forced to type it on the comp. when that event occurred long before you typed that reply there? check on scottmiller's comment up there and my reply to him. 

besides, your reply is way off topic so if you reply to me, type all the things you have to say and just send me a message on my inbox. 
yeerk21 in reply to twenglish1Sep 25, 2008. 11:00 PM
