Picture of 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


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

Step 1: Get all youre stuff

Picture of get all youre stuff

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!

how much fps do u get out of this if u use butane compared to hairspray
gemoney2 years ago
can u use a threaded air soft barrel and put a piece of paper so the bb would not fall down instead of dropping it down the barrel
gemoney2 years ago
ok do u know where u can get a multi tool because I opened half of it and the parts are out of place now and I cant open the case now
gemoney2 years ago
can u fire paper darts from it
nibbler125 (author)  gemoney2 years ago
You can fire just about anything out of it that you can from any other mini potato gun
gemoney2 years ago
but the gas would propel the bb out of the barrel allowing u to put in new gas I guess

how do u make a magizine for the gun so u don't have to drop the bbs down the barrel
nibbler125 (author)  gemoney2 years ago
Im not sure how you would make that work, you need to have an open breech so when you put in new gas the old exhaust can go out the barrel.

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

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

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.

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 (author)  ZachMaker5 years ago
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.

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

can you use hairspray
nibbler125 (author)  mossjo146 years ago
i wouldent mostly beacuse hairspray gunks up youre gun
how about  deodorant
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.

if I don't have butane or propane, what could I use?
nibbler125 (author)  Kaiven6 years ago
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
i think i'll try hairspray or alcohol in a spritz bottle, but if I need to I will use a lighter.
achol if you put too much will kep burning, maybe meling the plastic or softning and making it blow up next time
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...
its probalby wiggline around the the curve of it is bending and snapping it? try moving it more near the hing of the handle

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
Barrel is spelt Barrel not Barrle

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
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
sweet looks nice, but i think it looks more like a luger than like an uzi (sorry) nice idea 5*
Lugers are awesome
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)
Yeah and it might even be able to pass off as a luger. A Potato Luger.
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
