How to Make an Engine Mount for a Model Rocket

What You'll Need
Engine tube
Two centering rings
Engine hook
Utility knife

An engine mount helps to hold your rocket engine in place so you can launch the rocket. This article will explain how, instead of purchasing an engine mount kit, you can build the engine mount from scratch.

Step 1 - Purchase Materials to Build Your Engine Mount

Go to a hobby store and purchase an engine tube, which is used to house the model rocket's engine; an engine hook, which holds the rocket in place; and two centering rings, which hold the engine tube in place when you launch the rocket. Be sure to purchase materials that match the size of the model rocket you own. 

Step 2 - Assemble the Engine Mount

With the utility knife, cut a 1/2-inch slit in the engine tube. This slit allows you to fit the end of the engine hook at a right angle. After you make the slit, insert the engine hook into the slot.

Step 3 - Place the Centering Rings in Position

Mark about 3/4 of an inch from both ends of the engine tube. These markings are necessary for you to position the centering rings. After marking the engine mount, place the centering rings on the engine mount. With the centering rings in place, glue the center of the top of the centering rings. Start with the bottom ring. Attach the engine hook to the centering ring and holding it in place, allow the glue to dry.

Step 4 - Attach the Model Rocket

With the glue dried, turn the engine tube upright in order to position the engine mount for use with your model rocket. Make sure that the engine hook is set firmly in place and that the glue has dried completely before you attach the model rocket. Lock it to the engine mount in order to ready your rocket for firing.  

Step 5 - Launch the Model Rocket

Now you need to take the model rocket to an area where you can fire it to see if the mount has been properly affixed and the engine is working. Go to a large, open outdoor area and follow all safety precautions before you begin the launch of your model rocket. Once you have cleared the area, fire the rocket.
