| After fins slots were cut into the main body tube the motor mount was inserted into motor tube. I then used rope and old motor in a tourniquet type application to tighten the air frame around the rear centering ring. I inserted screws into the four t-nuts to keep epoxy out the inserts. I then poured enough epoxy to fully cover the rear centering ring. Each screw was then turned one turn every half hour so as not be be epoxied in place. | Prior to inserting the motor mount into the booster section it was disassembled, removing the 3rd, 4th centering rings, and bulkhead plate. Once the mount was epoxied in the booster section the at the rear centering the motor mount was re-assembled inside the booster section epoxying each centering ring and bulkhead consecutively. | In this photo you can see the Bulkhead plate
installed prior to being epoxied in place. You can also see part of the recovery system
hardware. Below you can see the 3/16 wire rope used as a connection point for the
shock cord. |

| I decided I did not want to fiberglass the Booster section, but I did decide to double wall the booster section from the top of the bulkhead on the motor mount to 6 inches below the top of the section. This is to allow the payload coupler to sit properly in the booster section. I used concrete form tube as a double wall. It was cut down to fit snugly into the booster section. Here you can see it as it was epoxied into the booster section. | In this photo you can see the additional 24 inch Airframe that I added to the booster section. The booster section now stands 7 feet tall. I added the additional airframe to increase the size and weight of the rocket which will reduce altitude. Oh, by the way in case you are wondering, that black blob next the the rocket is my dog Emmett. He loves going to a launch, but hates the noise. | In the above photos you can see second wall installed into the booster section. With the exceptions of the fin fillets the booster section is complete and ready to go. |
