Free Plans For Building Your Own Homemade Model Rocket Kit

If you're looking for an inexpensive hobby, and sending a rocket into space interests you, then check out these free instructions and list of materials for building your own model rockets!

Building and launching homemade model rockets is a great hobby for kids and adults alike. The materials you need - balsa wood, plastic, tubular bodies, nose cones, parachutes, glue, paint, rocket engines, a launching pad, et cetera, are readily available at most hobby shops. And, they don't cost a lot of money to purchase either. After your rocket is built, the only thing that you'll need to keep buying for it is more engines. One engine launches a rocket up into the air once. After that, the engine is spent and needs to be thrown away. You might have to purchase additional materials, of course, if your rocket crashes and you need to repair it.

If you want to build your own homemade model rocket, a basic plan can be built by using a hollow, tubular body and a pair of balsa or plastic triangular fins. The fins are secured to the body with glue. They're positioned one on each side, near the bottom of the tube. A nose cone, (which is also either balsa wood or plastic), with a parachute attached to its end, is pushed into the top of the body. The parachute is packed inside the hollow body. An engine holder, which can be a simple wire device, is attached to the bottom of the body. And, finally, a launching guide, which looks like a piece of a drinking straw, is glued onto the body of the rocket. After the glue has thoroughly dried, the rocket is then painted, and decals can be applied, if you wish.

Basic rockets like this one can either be very tall- two to two and half feet in length- or they can be small- as short as eight inches long- or, they can be any any length in between.

To build a variation of this plan, the rocket can have four fins on the body instead of just two. The additional pair of fins is attached to the body of the rocket, about half way up. While the other two fins can help to make the rocket fly straighter, they will also add a little more weight. The lighter a rocket weighs, the more altitude it will get.

In order to make sure the fins are positioned on the rocket straight, and an exact distance apart, you should use a ruler and a pencil to measure and mark lines on the body. Then, glue the fins onto the lines. Straight fins not only look good, but they also allow your homemade rocket to fly straighter.

Another plan is to build a homemade rocket that looks a little different. This rocket has a ring around the fins. Instead of triangular fins, the fins are flat on the outside. This allows the ring to fit around them flatly. To build this type of rocket, first, assemble a model by using the basic design. Except, make the outsides of the fins flat and straight. Then, cut a thin piece of cardboard that measures about a half inch in diameter. It, of course, needs to be long enough so it reaches completely around the rocket and its fins too. Carefully curl the piece of cardboard several times around a round object. Then, position it onto the fins, and glue it down securely. You'll probably need to use straight pins to hold the cardboard ring to the fins until the glue dries.

No matter what plan you use to build your homemade model rocket with, the true test of success is when you put an engine in it and you place it on the launching pad. When your rocket is shot into the sky, it should fly straight up and not meander across the sky. If you're not satisfied with the flying of your rocket, simply recheck the fins, nose cone, and other parts of the assembly to make sure they are properly installed.
