Introduction: Model Rocket Engine Launcher

About: I build things and play video games just like any and every other American.

launch those old model rocket engines laying around your room or garage with this fun and not so safe instructable!

tools:
glue gun
dremmel tool/jigg saw
kudos box
ruler
calculator (optional)

supplies:
tube
rocket engines
plug (for tube)
Launch button(included when you buy a rocket kit.)

Step 1: Get a Tube!

The first one i made was a PBC pipe in my backyard, then aluminum piping, then a toy squirt gun. either one is a great option, just take either one and seal off one end! Then use a jigg or a dremmel tool to cut a SMALL hole at the base were the engine will stop so the starter can pop out and hook it up with the prongs on the launcher button thinga-ma-jig.

Step 2: Build the Rocket Body!

to put fins on the engine, put the engine inside the tube and measure how much space is left of the diameter. divide that by 2 and that is the width of the 4 fins!

ex.
diameter of tube:1 inch. w/ rocket engine in:1/2 inch, divide by two:1/4 inch
1/4 inch=width of one fin.

Step 3: Make the Fins!

Now that you have your mearurements, use thin cardboard like on kudos boxes, and cut your fins to the desired width and length according to the previous step. Attach 4 of them to the engine using a hot glue gun, and make sure the fins are all the way to the front of the engine, or it will fly (even more) out of control. Make sure the engine falls to the bottom easily or get something long to ease it in with.

Step 4: Launch!!!!!!!!!!!

Pull the starter out threw the hole you made, and hook it up with the launch button thing. People, I can't stress this enough, MAKE SURE THE HOLE IS FACING THE GROUND!!!!!!!!!!!!!!!!!!!! I'm typing with a smoldering giant band aid on my wrist because I wasn't paying attention! Anyway, hook it up, keep the wires away from the hole, and send that mother f****r to outer freakin' space!!!!!!

    PVC not PBC. i am making a pvc vinigar and baking soda rocket launcher. i will post instruactable anout it when done.

    I think you should include a design for a rocket with the launcher, this by itself is not realy a rocket launcher but rather a rocket motor launcher. And you might want to include something about safety, it is usualy very important.

    Does it have much recoil?

    nice man needs a cleaner look but cool idea

    This is sickkkkkkkk! I am so doing this! Thanksssssss!

    fusionstar916 is a spammer. He puts an ad up for his site (hotpyro, crazypyro, or hotcrazypenisenvy) on every pyro-related instructable.

    Hit "flag" on his comments, and let's get him removed.

    im with ya lets take down these self-promoting advertisers set on destroying the point of reading comments to get half way through and realize its another advertisement instead of helpful advice FLAG HIM RIGHT BACK TO WHERE EVER THEY SEND THOSE _______ ______. (you can fill in the blanks yourself)

    yeah... my first one was all out of metal and was intended to be like a bazooka ... (>------ ... but you would lose the side of your face due to exhaust fumes/ blast...

    dude, ur gun rocks, but could you please email me more about why there is a hole in the side and how i can ignite it?

    rolling aluminium foil ( the kind used for wrapping food) around a tubular object and reinforcing its layers with glue can give u the desired length and diameter of the launching tube ;) ....when properly done the results are nothing less than absolutely what u wanted.

    a simple challenge: Do Better With Similar Materials. Then you'll be in a position to judge it.

    just because it doesn't have the cheap and sleazy looks of an M-16 doesn't mean it's crap. I actually quite like the bronze-y spray paint finish.

    nice duck tape thing i wood just get a coper pipe and cover one end half way then shove the engine into the other end.
