1) A generous amount of slow epoxy is applied to the body tube.
2) The forward centering ring, middle centering ring, and motor tube will be inserted into the booster section. It will not be inserted fully. The additional adhesive and carbon fiber filler will be applied with a syringe through the fin slots.
3) Once injected, the motor tube will be slid in fully and allowed to cure. The rocket will be inverted several times to allow the epoxy to cover all the surfaces fully between the forward and middle centering rings.
4) After it cures, a fillet is placed above the top and below the middle centering rings.
