Home Made Rocket Launcher

at 7:55 am. Filed under DIY Hacks, Insane Equipment


If you have some of the holiday fireworks left over I can’t think of a better way to get rid of them that build a Home Made Rocket Launcher. More pictures can be found here.

“Building the first stage rocket launcher was incredibly simple
1) 2″ pipe over 5′ in length to avoid getting blowback in you face
2) Rocket engines, ignitors, lauch controller or any device that puts out about 6v
3) Balsa wood and superglue

Cut balsa wood to a fin-like shape, glue onto rocket motor, put in ignitor, profit. This may sound oversimplified but it really isn’t, we were able to achieve a flight of over 2 city blocks with the launcher horizontal with this exact setup. The deviation on the horizontal axis for this flight was about 3′. The engines are about $3 a piece and each rocket ends up costing us about $4 a piece, so you don’t want to throw them away, but it isnt outrageous. You can of course, use a standard model rocket, however don’t be prepared to get it back in any usable condition, and be sure to take out the parachute.

We are currently trying out new varieties of fins and motor configuration to achieve a steady flight path with regularity, it may take us awhile to get it right, but i assure you, stable flight or not, it’s damn fun. If you have any suggestions as per the launcher or rocket construction, post and i will most likely try it and give you a field report.”

    dude i can make a sub morfcompactko39embarisor with home made supplies email me a jimmy nuetron.org loooo

  2. D Says:

    I think you should close toilet flang end of the lauch tube so the rocket’s thrust pushes off something to push it forward instead of shooting out the back. you’ll have to come up with a new way to insert the eletrical launch wires though. Also try a fin configuration like the nurf vortx football’s. I haven’t tested this yet, but those nerf balls go pretty far and are pretty stable in flight. just don’t go around with your launcher saying anything about jihad unless you want to be answering a lot of questions.

  3. Iblis Says:

    so, how straight does this rocket fly

  4. Alan Parekh Says:

    I would call it more of a spiral motion.

  5. Iblis Says:

    have you thought about useing real rockets

  6. Spuddin Says:

    hey somebody used my name in here to make NEGATIVE comments! anything negative is not by me, srry.

  7. lisa dickey Says:

    I love how you make bottle rockets I want to learn how.

  8. megadethkillers Says:

    something i used to do when i was a kid in the 80s. I would build the launcher much like you did, but i did a few things differently which you may find ups the ante a little bit.

    1. remove all other stages from the propellant engine except for the solid fuel. you can do this with a screwdriver because when you get the ejection charge and delay out (they are soft) the solid rocket fuel is much harder and you can’t scrape much further with the screwdriver.

    2. Take approximately 6-9 “D” size engines and remove all the extra engine material as described above.

    3. take the remaining fuel and remove it, either by cutting the cardboard “wrapper” or drilling it out. either way, you want enough fine, black powder to fill your standard size rocket, whatever you use.

    4. whatever size rocker engine your kit recommends, use a larger propellant rocket. if the kit calls for an “A” or “B”, use a “C”. if the kit calls for a “C” make a bigger hole and use a “D”

    5. pour all the black powder into the tube of your rocket, filling it most of the way. leave a little space and glue on the nosecone with crazy glue or model glue.

    6. before you launch, make sure you have a fire extinguisher nearby!!

    7. Only launch at angles greater than 45 degrees or you might blow someone or something up. unless that is your intent.

    8. Don’t hurt anyone, and don’t destroy anyones property who doesn’t deserve it!

  9. Commando Says:

    Rocket launcher was SICK! I am thinking about building one of my own. Yours lookes so professionally made, and I will probably copy your design.
    P.S. whoever it was that wants to join Hezbolla, I’ll beat your @#$%&*! before you get there!

  10. robert Says:

    hey can u show me better blueprints of this and how long it takes asap

  11. sk Says:

    In regards to your unstable projectile:
    Rockets will follow an unstable flight path if the center of pressure is at or above the center of gravity. Given that fin design, this is exactly what is causing your problem. You can either move the center of gravity forward by adding weight to the nose, or move the center of pressure back by only having fin surface on the back end of the rocket.
    Leave it to
    the government
    to explain it in gripping detail…

  12. Meg Says:

    im doing a school project and making a rocket, how much sugary coca-cola should i put in a 2 litre bottle

  13. Alan Parekh Says:

    Hi Meg,

    If you are talking about this type of reaction

    then you need to use a full bottle of diet coke.

  14. JRush Says:

    Why do we assume we know mor than the next guy? Why don’t we all build what we know and go against each other. Absolutely brilliannt.

  15. karl Says:

    hey if u wanna make it explode on contact (the rocket i mean) take a cheap BIC plastic lighter (lower quality plasic = best) and pull off the metal bit. put the plastic with the fuel inside on the nd of your rocket and voila

  16. shane Says:

    were do you buy the rocket engines and ignitores?

  17. shane Says:


  18. Alan Parekh Says:

    Shane, you can buy rocket motors at any hobby shop.

  19. saurav Says:

    i really liked your project and i’m willing to make but the question is how did u make the igniter???

  20. Alan Parekh Says:

    Hi Saurav,

    You can get the igniters at any hobby shop that sells the rocket motors.

  21. crazy red neck Says:

    hay i am makeing one but mine looks like a javilen it has two igniters that have 2 cupasiters to quikly provied ignishen allso mine uses F size moters the rocket is serounded by stirefom that brakes off after leaving the launch toub the roket is plased off set in the fome so it gos slitly up right out of the tube 2 counter gravity allsow i have a red dot sit billt in to the side im starting to put payloads in right next to the solid fuel rocket moter to time detinashen i use rocket engens that have delad forwerd exploshens NOTE i lauch in the desert so no one gets hert

  22. glenn Says:

    wow thats sweet iam going to build one

  23. glenn Says:

    iam building one and i have 72 rockets for it to shoot out of it its cool

  24. bob Says:

    nice now put some c-4 on the end and see what happens
    when the feds come to your house

  25. kris Says:

    Hey when ever I look for really cheap rocket engines for around $3 like you explained I just find quite expensive engines for R.C planes. Can you post up a link showing me these cheap engines and detonators? And probably a picture of one so I know what I’m looking for?

  26. kris Says:

    actually, didn’t look at all the pictures before I posted that so i see its part of a firework now. is it just like a choped up roman candle or something?

  27. Clark Hotels - A Group of Luxury Hotel Says:

    looking awesome ..!!

    i also gonna try this ..lolzz

  28. Ben Wardill Says:

    cool…. i want to make one. I heard about this luxury hotel chain called clarks that is in need of some demolition 😛

  29. reno Says:

    I would to really like to make it at home but i can’t can u send me directions to my e mail at reno1@live.ca

  30. lone wolf Says:

    if you want a bigger boom i think you could plug the back up and put mortar fire works, it would be a better ..uhm lets say display. but you would also need to be in a big field and firing relatively in the upward direction since those mortars are used to make the big explosions that you see at disney and stuff.

  31. sgt. Oink Says:

    nice idea but make it so u can aim with it

  32. 6644Invader Says:

    I built this exact body tube. Great idea! I altered the interior by making a sheet metal tube that ran the length of the inside with 4 groovs to hold the fins. Inside the scope mount, I put a cheep scope and then calibrated it with several test fires. With the help of an ex-NASA engineer, I designed and built several 2 foot 4 inch long rockets ($30 each) that have an 800 yard capibility. The nose cone has 1.83g of RDX in it with 112g of plastic explosive behind it. I’m pretty confident that I could take out a mid sized vehicle with it. Thanks for the idea!!!

  33. invisable Says:

    OK, I am willing to pay for one if I have to, but it needs to be able to fire long distances and shoot strate. I am also interested in getting hold of a morter gun, if any one gots and idea of how to get one.
    my email is 00THEPATH00@gmail.com please contact me there.
    also anyone truly interested in helping me I live in ohio and they need to be near me, I might beable to work around this though. I dont think its a good idea though to try and send one through mail or on a plain, I will not give out any names or contact informaion. but I would like to get phone numbers and emails send to my email once again 00THEPATH00@gmail.com
    and we can work out details, also can help with sending very detail insturctions and also digrams
    thankyou and have a great day and I liked the video

  34. Kerr Says:

    hey so far ive built the design for the body but im having some problems building the rocket. I have D class motors and i guess what u can call “helicopter fins” from some firecrackers in the past and was deciding to glue these fins to the engine. To add a body do u think it would work to add like a small soda bottle to the engine and add some small fins to that to add stability? I’ve tried to figure out ways to where it would fit but also be aerodynamic as well.

  35. jonathan bigelow Says:

    you guys are so crazy so i will tell you what/this i want more

  36. jonathan bigelow Says:

    also i have tried what you guys have on the photos and i just think that you guys are just the only people in the world that i know that can build something that big tall and or big i was just suprised and i knew that once that i looked at your photos that i was with no doubt i mean i was with nodoubt going to type you guys something very and it would be so big that you guys would say wow i had never seen a good or better coment than this befor

  37. Leo Says:

    OK I would love to have a rocket launcher thanks for the info on how to build it looks like fun I may make a 2 person launcher with Huge Rockets and fire it at test targes (junk cars) in the desert (hopfully I can reserve the distance a mile or two so I can fire it) would also love to have huge explosives on the end for fireing at the sky

  38. elfonso Says:

    your an idiot, it looks like your firing it off in a rural area, not to mention the pvc pipe looks way to flimsy, it would serve you right for one to explode and knock your eye out

  39. ghost Says:

    for those of you that are interested you might want to have a look at the works of Barnes Wallis
    he was a world war 2 British bomb inventor who designed things like the grand slam tallboy and the dam bomb along with many planes as well, he solved the stability of his bombs by offsetting the fins with a slight spin meaning the faster if fly the more it spins, i point this out due to in your video its show the rocket spiraling out of control the same method is used in a lot of cast iron bombs today

  40. chris b Says:

    hello i have made a couple of these… just for fun… lolz i show them off at a artillerary festaval in tennesse where they let u shoot any gun u want… they wvwn have mortor ammo and tank shells =P lolz a few years ago i bought a .30 cal mini gun that mounts onto the roof of a humvee… i just bought a humvee… oh sorry… lolz any way i have some ideas for u to try… one make bigger rockets that have fins that pop out… or take a card board tube that is just a lil smaller than ur launcher and that and cur the tube to make 1in thick rings and put ur fns in there and have one in the back and one in the middle or just one glued streight to the engine… ill try to get a hold of u and send u some diagrams…

  41. Ten Free Construction Projects (That Are Really Bad Ideas) Says:

    […] Launcher To be fair to these hackers, the “rocket” in question is a (somewhat) harmless home rocket, not some sort of death-dealing device firing straight at your opponents. And they’re just […]

  42. joseph Says:

    look man, your rpg is very very good but i’ll tell you about more advanced just e-mail me on this e-mail and you will find a better rpg than your’s .. and ill show you a video and it takes really few HOURS , cuz its really dangereous firing rpg!! im waiting!! XD


  43. DERP Says:

    I hope you’re on our side.

  44. drexel Says:

    Is that big monster real? You know, You shouldn’t have that thing out in public.

  45. Dany mathew Says:

    when i was 17n,i and my frnd made a rocket but not like that.

  46. Luigi Fulk Says:

    This is the precise weblog for anyone who needs to find out about this topic. You realize a lot its almost laborious to argue with you (not that I actually would want…HaHa). You undoubtedly put a new spin on a subject thats been written about for years. Nice stuff, just great!
