The accidental pocket jet engine parts

Parts that can be easily obtained for killerjackalope's jet engine. Includes body of jet, and the jet nozzel(probably not as good as what he is thinkin up )

Step 1 Materials

Ok, what you need is:

an old R/C car controler
needlenose pliers
a small hole puncher
screwdriver
old airsoft gun(or new cheap one)

Can you make your instructions a little more clearer for making a jet nozzle?

[stephenniall]

this reminds me of a hobby blowtorch i have you pour methalated spirits in it and the vapors Make the flame !

[samando]

Hey, nice instructable! I also noticed the ruler. "fox valley savings" Is this fox valley in Australia?

[triggernum5]

Have you considered giving it a direct O2 feed? You could probably crank it higher.. Electrolyze some water and pump it to your intake.. Its a nice job.. I feel sorry for ppl who waste money on toy guns etc just to get basic parts that can be substituted though.. I made some jet nozzles to give my butane torch (which actually uses cheap lighters as fuel cells) various flames.. I did quite a bit of research, I should still have a bunch of data still on my hdd.. (If I find them can you read *.djvu files?) I also ended up making a similar flame out of parafin, but that took alot of preheated O2.. Without the heat I couldn't fully burn the parafin as it melted, and got drops out the bottom.. I was running it through 20' hot coiled copper tubing Its pretty cool what can happen when your fuel gets to burn oxygen rich.. Any flame that can be strengthened by blowing on it is oxygen deficient, and thats just wasteful..:)

[Gamer917]

You could use hydrogen gas along with pure oxygen , but it would get very hot because hydrogen burns with a very hot flame

[killmore231]

actually if i wanted to, i could just use a tank of oxygen i have back from when i was in welding, its a small one so it dosent have much in it but it will work. oh, btw run this by killerjackalop[e to if you havent already

[Mario1]

Well i did the nozzle and when i fired id up and it was just like i am igniting a lighter :O there was no "jet flame" help :( :( :(

[Mario1]

Is there any hole on the "v" thing? Please, reply.

[killmore231]

yes, there should be a small gap between the two pieces to allow the gas through.

[Mario1]

Ok, thank you :) i'm subscribing! :P

[junits15]

i have a metal pen body i am a little confused about the nozzle thing where dose the v go? am i cutting the tube or pushing it in? its the the nossle that lets out the gas into the pen body? somebody help!

[killmore231]

Yes it is the nozzle. And you have to bend the end of the tube to for a "V", or if you can a "+" but that is much more difficult. So you are pushing in on the tube to create the nozzle exit.

[junits15]

oh now i get it, this is just a method of making the end smaller.

[killerjackalope]

I actually use a 6mm aluminium tube from a BB gun in this lates design that's wierd, when I first saw this I was like huh, didn't someone mention this idea then I noticed it was you, i must add the new bit, also aluminum is a good material...

[killmore231]

hehe i was looking through my stuff to find a good body, a metal pen eluded me, then i look at my old broken airsoft gun and it hit me that it had a metal barrel, so i took it out and it worked like a charm

[killerjackalope]

Yeah, the newest version is quite insane, nearly finished, what I need is more fuel/air coming through the nozzle, time to make my own.

[dark_stars_2000]

have you tried a small air compressor? also that computer fan idea posted on your instructable by a reader was quite clever two :)

[koolsk8ter111]

ohh if this tube don't work do you know where I can by A diferent one?

[koolsk8ter111]

Yes I took mine out of the airgun, but i'm saying mine is dicast metal if i'm not mistaken. here is A video of me holding it click this link:

[killmore231]

it should do fine, although you may want to do the first few tests outside, because mine, when i used a pen tube, gave off quite a bit of smoke.

[koolsk8ter111]

sorry just play the video there is no link lol

[koolsk8ter111]

I think my metal pen barrel is dicast metal.

[killmore231]

what do you mean by that? The gun barrel us meant to be a replacement for pen tube.

[koolsk8ter111]

Sorry. not Cm it is mm. So its 8 and a 1/2 mm long and a 1/2 mm wide, with a screw head on one side. (The pen barrel in the last comment I made) sorry I said Cm it is mm the pen barrel lol........

[koolsk8ter111]

Is there A tool I have to cut it with? And my metal pen barrel don't look like A barrel, it is thin with A screw head sticking out on one side. Can I still use it? Its about 8 and a 1/2 Cm long, and A 1/2 Cm wide.

[koolsk8ter111]

I took my barrel out and it has no hole. do I have to cut it? And if I do have to cut it, what do I cut it with?

[killmore231]

it should be open at both ends, and you just have to find a way to get the nozzel onto one end with an airtight fit. I used super glue, but you may want to find something more heat resistant.

[thedog458]

hey ummm this is gona sound dumb but why do u need the v shape at the end?

[killmore231]

if you didn't the gas wouldn't come out as fast as it would through a smaller nozzel. faster fuel flow and a leaner mix(I think) means a better jet. doesn't have to be "v", the optimum is a "+" but that is hard to do right, so I stuck with the "v". but mostly its just about fuel flow

[thedog458]

ok thanks

[killerjackalope]

Oh the jet engine research is going well, when I say research I mean insane ideas with dodgy testing has led me up to the point of using a set of parts but will have a good instructable including larger nozzle construction and it'll now be a bit closer to a fully fledged jet engine, still non turbo, I'm running a butane torch as a tester fuel source but by the end I might even get it running on alcohol or lighter fluid...

[killmore231]

oh, it just happened to be broken, so i used it. i have a new antenna so i can still use it :)

[GorillazMiko]

This isn't all the parts, huh?

[killmore231]

no not all, just the ones that i found the hardest to get. found a simple solution to them, and decided to post them. really all you need besides this is a way to hook it up to a gas source.
