Bryan Oyan - 1/12th Scale Track Design + Manufacturing

During weeks 12 and 13, we took part in presenting our 3rd and final presentation of the semester. We discussed our prime design and our current designs, in addition to getting feedback regarding our design from the other teams, supervisors, and Dr. Furman about some changes we should incorporate into our design. One of those suggestions that we incorporated into our design was increasing the track's switch section's radius from 11 inches to 25 inches. With this design, we are hoping to create a sense of uniformity with the full-scale model, by increasing the turn radius, just like the full-scale iteration of this project. Other teams presented as well, which gave us a proper sense of overall progress with this project. It seems like everyone is making good progress with their projects and hopefully we will be proud of our designs during implementation next semester.

During these two weeks, the team members got together and worked on creating the straight sections of the track. Throughout the semester, Kevin Brasil has worked on fixing the tolerances for the bracket's lego design, therefore we had enough brackets 3-D Printed and used the drill press and spare fasteners in the shop to put together a working model of what we cadded out on Solidworks. This was completed successfully, and we manufactured 2 straight sections by the end of week 11. During end of the session in week 11, we met up with Dr. Furman and discussed some issues regarding our design and hashed out some of our ideas, manufacturing, and cost issues with him. We suggested downsizing the track from 1.25" 6061 aluminum to 1" 6061 aluminum to reduce the unnecessary costs of the larger parts. In addition, there are sections that are still ambiguous to us, such as manufacturing the curved portions of the track due to the concentricity issues and the tight tolerancing that
