    sorry if this is in the wrong section. Im the new kid.

    Anyways, I am wondering if you guys can show me a link or give step by step instructions for building a rocket. I have done other fun explosives and am know wondering how to build one of these suckers. I can get my hand on tons of chemicals, so I dont need the hardware store version. Thank you very much.

    I assume you are asking how to design your own rocket motors. Well, do you know anything about how to build a rocket itself? Assuming you can make a motor (the engine), you don't want it flying all other the place and ignite some building or forest.

    I'd say learn how to build rockets (of your own design) using A-G motors you can get at the hobby shop before making your own motors. And making your own is pretty iffy because you need to get the proportions correct and if it is a solid motor rocket (like those of black powder or ammonium perchlorate) you need to make sure there are NO air pockets in the mixture because those act like small combustion chambers.. meaning possible explosions).

    But assuming you know all of this stuff... then you shouldn't have trouble doing a search on google and visiting your local library to learn some chemistry and nozzle design.

    I did know about most of that stuff, but I don't really want a HUGE rocket with a motor or anything. I'm looking into useing things like Potassium Nitrate or just gun power for thrust instead of a motor. Thank you very much though for the information. I'll take a look at thoughs motors just for kicks.

    Well even if it is just a small rocket, you still need to learn how to build the rocket itself. Fin distribution, weight, center of gravity, drag coefficient, etc... It's not the hard but just get the hang of it.

    Rocketry (as a hobby) doesn't get into serious fun until you build all of your rockets from scratch... are huge... and put out a lot of power. 13,000 feet is fun.

    Oh course, when making your own motors, be sure to test them outside of a rocket. Putting them on a scale or something.. measuring thrust output versus time and things. You'll need to know these things.

    I have never made a motor but I used to build rockets and launch them. I have a few home-built rockets but I always launched them with Este's or Aerotech motors (Aerotech is where the fun begins )
