mini potato gun hot glue gun

here is a neat little gun I built to help with how hard it is on you're finger to light that tiny pizo ignighter. it fires airsoft bbs at about 200-250 fps do not try to build this gun unless you have experience with mini potato guns or else you will have a very hard time building it and trouble shooting. this gun is very sensitive on what it uses for fuel.

UPDATE the pizo ignighter broke so I am going to try my luck with a camera flash. also I have upgraded the barrel to a metal one I got out of an old airsoft gun. and last using butane nearly doubles the power of the gun and is sounds like a 22cal rifle going off


UPDATE

I have stopped using the cap right now I just hold my finger over the hole and it works just fine if not better

This is a great Instructable, but you need to add a main image of the final project to the intro step. Please do that and leave me a message when you have so that we can publish your work. Thanks!

i made somthing similar, a MAGNUM out of a old cap gun and redbull shot (empty of course) ans a small peice of pipe to fit snugly in the shot, and made it up and it wasnt working , so i tipped it back and fired, no eye brows and eye lashes :( moral of the story, lighter fluid is heavier than air so it sinks down

[cschoemans]

this thing is insane. I made a bigger chamber and use a special mix of 60 percent propane and 40 butane did need to put in some isolation because i started melting my gun because chamber is made of magnesium so mare heat but no elctric conduction did need to use a drill but still great design

[billbobby]

 can you use axe for propelant?

[ilpug]

You most definetly can. however, it will smell funny.

[haaiids]

hello. i have a hot glue gun but it has the triangle screws...any ideas of where to get the screwdriver ??..thanks.

[ebubbula]

I had that problem once too i just uzsea a real small alan wrench

[ebubbula]

Sorry used not uzsea

[nibbler125]

once again only use butane or propane its a finicy gun and will not fire as good as it can with hairspray. rember hairspray and deoderent are only flamable beacuse of one or two parts. all the stuff that wont burn just gets left behind. butane and propane is all boom and no poop burning cleaner and you can use a higher mix ratio.

[ZachMaker]

i have no idea what ur talking about when u say hollow compressor thing u dont have a picture of it outside the highliter and i dont know what 2 do could u explain but other than that its a really awesome desighn

[nibbler125]

found out its not a air comresser part. Its something from a brakeline from a truck. (i save everything) I would go to autozone and search the random fitting area untill you find something useful.

[mattccc]

anything that has butine propane or any other flamable substance in it will work

[sjoobbani]

 Nice, 

[mossjo14]

can you use hairspray

[nibbler125]

i wouldent mostly beacuse hairspray gunks up youre gun

[jcosi97]

how about  deodorant

[MadBricoleur]

I use rubbing alcohol put in a mini spray bottle. one short burst of it when held about 4 inches away from the chamber opening is good for a shot.

[cowscankill]

if I don't have butane or propane, what could I use?

[nibbler125]

i got it to work on zippo fuel but youre best bet it to get a butane jet lighter for like 5 bucks and just press the button so gas comes out and hold it for a few seconds

[cowscankill]

i think i'll try hairspray or alcohol in a spritz bottle, but if I need to I will use a lighter.

[franklinonline]

achol if you put too much will kep burning, maybe meling the plastic or softning and making it blow up next time

[firefighter1333]

sry for asking so much but i got an other question sooo hope u asnwer well here it is; for some kinda reason ma ignitor keeps breakin the whole time (so i need to replace it all the time;ANOYIN), it breaks each time on the place where the 'button' is (like the neck) do u kno how to solve this (alrdy tried to make te neck stronger; didnt work, there from lighter wich are sumthin like 10 cents a pice btw...) sooo...

[franklinonline]

its probalby wiggline around the the curve of it is bending and snapping it? try moving it more near the hing of the handle

[kwlweapons]

Hm if the creator is still there... some improvents/mods I would do would be 1. Make a sparkstrip design to improve reliabal ignition.. with a sparkstrip you can have up to 4 SMALL sparks in your chamber so that it can fire in the first clicks .. This is extremely helpful specially in mini guns. 2. For fuel I would recommend to just get a refillable butane mini tank and attached it onboard so that you can take it anywhere and shoot whenever you feel like it.. plus their only like 2 bucks and you'll get atleast 400 shots out of one. 3. For anyone out there having problems with the back "air compressor part" what I would do is just find a pill bottle or a w/e bottle THAT HAS THE SAME DIAMETER NECK OF THE BACK of your highler.. then just glue it onto the back and use the screw on cap that came with it... PROBLEM SOLVED Any questiones, ask... Anyway good job on the build im gonna build myself one... just a little bit more "Advanced" i might post it if im not to lazy

[Flash Gordon]

Barrel is spelt Barrel not Barrle

[aahutner]

when i made a mini potato gun it was very unweildy but this design looks great. i love how it fits into the glue gun. it looks nice

[stephenniall]

I bet you could add like a sliding mechanisimg in the barrel infront of the bit that lights up and use it to slide put ball bearings in Slide back shoot etc lol

[firefighter1333]

sweet looks nice, but i think it looks more like a luger than like an uzi (sorry) nice idea 5*

[Flash Gordon]

Lugers are awesome

[firefighter1333]

100% tru, actualy, to make it look more like a luger he has to paint it, add some kind a round thingummy at the bottom of the handholdthing (from the clip) and some kinda tube above (on the place where he has the space where u can see the chamber) for theignition hammer thing. just fros saying (:P)

[Flash Gordon]

Yeah and it might even be able to pass off as a luger. A Potato Luger.

[firefighter1333]

lol, only i think it isnt a good idea to use in real war lol XD (*sput* reloadin *only click* say darn and reload again sput say yes he is hurt (right...)) lol

[Flash Gordon]

That would be funny

[invisiblebluerobot9]

How far does this thing shoot?

[nibbler125]

good shot will go 30 or 40 yards

[firefighter1333]

if yo chamber is sumthin like 1 inch wide and 5 inch long and ur barrel is 1/5 inch wide and 8 inch long and u hav no leaks how far will it probably shoot then (please could u try to guess (cant measure maself cuz i live in very windy open land...)) pls answer...

[NIINO9]

do you have a video ?

[nibbler125]

yes its on youtube but normaly i can make the gun shoot allot better

[Father Christmas]

i see this having airsoft potential, namely because of the pen barrel lol

[apr1694]

wat do you use as fuel
