Nose Cone:
At first we planned to make a nose cone out of balsa wood, but then Andrew brought some PVC caps that perfectly fit on our rocket. So instead we planned on using the PVC caps because it saved a lot of time. It also ended us saving a bunch of time, because we didn't have any extra weight.
Body Tube:
Making the body was pretty hard, but we got help from some of the other groups who have already had experience with making rockets. The other group helped us tape down our very first layer, but after that we had some trouble putting the rest of the strips down.Putting everything together and working with wood glues messy. Our body tube turned out better than we expected, but there were a few bumps so we tried sanding the bumps down to make it even. Our tube was shorter than we planned so it was 12 inches, which was smaller than we originally wanted it to be.
Fins:
To make the fins we had to find the center of gravity, once we found the center of gravity the surface area had to be the same for both halves. Our fins ended just like how we planned and the surface area being 6.89 inches. We planned on using 4 fins, but the surface are wasn't enough so we ended up using 3 fins which ended up working out. Evan worked on the fins he got a piece of balsa wood, and drew the design of our fins on them. Then he got a razor and cut out the pieces. After we used a coat of pain and glue to make sure the fins would stick on properly.
Parachute, Shock Cord, and Engine Housing:
At first we wanted the parachute to be a square, but we made it to a circle. We made it out of a trash bag and we added tap to secure the edges. Once we added the duct tape we used a hole puncher to make the four holes then we got fishing line and tied it to the holes that we made. The fishing line was tied around the shock cord.Our motor fit in perfectly inside the body so the housing was not needed. The only thing we needed for it was a metal clip to keep it in place and to ensure it from not falling out.
