Engine Mount Assembly for Model Rockets

"The first step in building the big Bertha in this case, model rocket, is the engine mount assembly. Engine mount assembly is basically a tube that's going to hold the model rocket engine. That's going to propel the rocket into the air. The engine clip which is going to hold the engine in place when an ejection charge fires to pop out a parachute. Not a big deal. Spacers or washers you might call them, to help hold the engine mount tube in the main body tube of the rocket so they fit together. And it's centered in the body tube. Some glue and some measurement items to help mark the tubes where they go in. Like you need a pen to measure the body tube or a pencil, to measure the body tube where the engine mount washers and the engine mount clip holder go in the rocket."
