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

Step 1: Take Off the Nozzle, Not Needed Yet

just unscrew the nozzle , you can use the multi type ones but there more expensive thus are not used, the nozzle will be used some other time if it works then ill post it (rocket launcher!) bad quality on this photo sorry, but its really doesn't matter,you get it right?

Step 2: Adding the Tube, and Taping It

slide on the tube, wont be snug but just add some tape "just" to keep it in place let it wiggle , then add 2 skewers (cut the tips for safety) and tape it so it doesn't move

Step 3: Add the Stopper IMPORTANT!

Now just add the rubber stopper and make sure it fits well and doesn't fall out ( the one that comes with the blue thing is too small) also make sure the tabs are facing away from you

Step 4: The Bottle

just screw in the bottle it will be tight VERY tight make sure its all the way use a wrench or something if its too hard

Step 5: Drill the Hole and Add the Inflation Needle

drill the hole on the hard part on the bottom of the bottle ( you understood that right?)
and add the needle and with hot glue or silicone seal the holes around the needle so it doesn't escape

Step 6: Have Fun

put in your ammo the best is ones from blow guns tape a cone to a nail put it down the barrel pump and shoot! have fun!

Tips for firing:
For maximum out put make sure the edges of the ammo it snug against the barrel
one way i use is dirt
just hit the barrel on the ground getting 2 cm of dirt on the end ans push it in 1 cm away from the tip of the valve have fun shooting dirt its unlimited and goes very fast!


And please post

Step 7: Shooting, an Art Passed From Genrations

Shooting, ok maybe its not an art passed from generation to generation but there is a specific way i shoot things, if you read the tips you already now my favorite ammo is dirt, just how dirty it may seem is practically everywhere , and the benefit of doing this is :
1 free ammo dont need to build anything
and 2 your aerating your lawn ,sounds good right? < might take awhile..

i have no pictures sadly, mainly cause my batteries are charging, i really need a 15 min charger...

but ill post em once i have some good ones, this is how i do it

Dirt method:
1 hit barrel into the groud wiggle it more to make sure you dont have less than 1.5cm of dirt
2 use a round object slightly smaller than your barrel and does not have any holes, then push it down to about 1 cm away from the bottom of the barrel { you can do the math}
3 once done loading which takes about 40 seconds for me just start pumping (or use a air compressor) to 20-80 psi depending on bottle
4 just aim and hit the trigger if your good you can load/shoot in about 1.5 mins and still have about 50 psi , bigger bottle requires more pumping

Dart method:
1 load one dart nail facing out (duh! ) and make sure it has something to capture the moving air such as a paper cone taped to the back of the nail, makes good ammo
2 follow step 2-4 in the dirt method

Nerf dart method:
the same as above

happy shooting!

i will take pictures of my upgraded shooter i added a bolt action and scope, see if you can do it ans post your own pictures

<p>hi im having trouble finding a bottle that will fit on the end of the hose extention part what do suggest i do?</p>
Im sorry i cant send picture for some reason
<br>
This is what i got. Even though it looks hard, its basic air gun like this. I just added a stock longer barrels, ect. Instead of using a thin plastic water bottle, i used a my moms lotion bottles that can hold 120 psi.
<p>can i attach a tank of paintball and will it shoot well ?</p>
<p>does the size of the bottle influencing the power of the gun?</p>
This what I done so far
Does the inflammation needle have to be on da bottom?
is ter any alternative for pump???<br>
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.
i added a 2l bottle instead : ) <br>
i can't find a bottle that fits in teh nozzle :S
how far does it shoot? <br />
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?
<p>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?</p>
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<br />
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.
heres mine =p<br />
cool.. <br /> 5
wow a homemade gun/nerf gun with instructions that i can accualy understand, great instructable, 5 stars, i'm gonna start making mine tomorow XD thank you for posting this.
how does it shoot?
lol read the damn thing lollllllll
you pull the thing thats supposed to let the water out<br />
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...<br /> <br /> great job!!!! :D<br />
hi i feel yu
WARNING: don't over pump the bottle i will hurt!!!
Yah think
no i know from first hand experiences
it blew up on you?What psi was it or how many pumps?
i don't remember it was like almost 1000 pumps though, LOL
Where you alright and do you think that yeerk21 is a yankee
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
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&nbsp;occurred long before you typed that reply there? check on scottmiller's comment up there and my reply to him.&nbsp;<br /> <br /> 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.&nbsp;
some people never got over the civil war.
If you tape the bottle with duct tap, from top to bottom, and the bottle explodes, it will prevent shrapnel.
wrap ur bottle w/ duct tape so da shards wun go evrywher den it wun hurt so much:p
thats a good idea. you need to work on your english lol
iun ned 2 work on my english cuz i type lik tis on comp..wat u wan me 2 do type like this and have every you and I and other things etc...iun do tat on comp.
ok take it easy man
what is he saying?
i think he said "i dont need to work on my english cause this is how i type on the computer. what do you want me to do, type like this and have every you and i and other things etc. i don't do that on a computer"
yankee
i am...i usually tlk like tis LOL
uh...LOL?
laughing out loud or lots of luck I think
yankee
&nbsp;You should&nbsp;reinforce&nbsp;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&nbsp;realize&nbsp;is that it will also&nbsp;reinforce&nbsp;the bottle. The more tape you put on the bottle, the stronger it will be.
hey dude i love this design. if it works send me a vid, my name is ifen27
hot glue works best for a better seal
