Today was another great day at the hangar. TeenFlight 4 worked on the engine, the engine cowling, the wings, and the canopy fiberglass. As for the engine, the parts were inventoried and the battery holder and cooling system subassemblies were worked on. The left wing tip was also riveted and the wing is very close to being fully complete.
Also, students were exposed to a new type of material and process: fiberglass. Mr. VanGrunsven led a workshop to practice the skills necessary for this type of work. This included the epoxy and hardener ratios, how to cut fiberglass cloth, as well as how to apply it to the desired work surface. After some time, work began on the canopy fiberglass.
The multiple layers of fiberglass were cut to the different shapes and were then glued to the sides and top of the forward upper fuselage using epoxy resin. After the fiberglass hardens, it will be time to sand in order to achieve the smooth contours.
The engine cowling was sanded and drilled to align with the hinges and other parts of the firewall.
Have a great Christmas and TF4 will see you in a couple weeks!
