Hi,
this week I took charge of ordering PLA filament we needed, but that required us obtaining numbers from the positioning team who did not reply via Slack. I will be talking to them tomorrow with regards to the dimensions, quantities, and files of the brackets they need. I also drafted a design of the collar that would be used to support the solar mount that the solar team needs. However, Jez built upon my design and drafted a better design. I started the presentation, but since we will be presenting the following week, I have been focusing more of my attention on creating a jig that would allow us to quickly fix the bracket to the correct location on the rail we want to weld to.

Hi,
this week I worked on figuring out what the Solar Team needed from us in terms of aluminum material and the support their solar panel mounts would need. It is critical to understand their position because if we focus solely on our team, when the time comes, the entire project would not come together smoothly. I also did research on how to FEA a 70% in-fill PLA object but the results were fruitless. All I could find was a chart on the how strong it is. But just knowing the strength is not enough because I also would need density and other properties to plug into SolidWorks to obtain a logical representation of the stresses and strains.
This next week, I will be working on drafting some designs for the support structure necessary to fulfill Solar Team's needs but also fitting our own parameters (e.g. easy (dis)assembly, low material/cost, etc.). I will also be working on the presentation this week.

Hi,
this week I researched why our material is not bending the way Kevin had anticipated. Therefore, it means our material is not the exact same product as the old heat-treated ALU 6061, despite it saying so. I also prepared the metals for cutting - we have cut about three so far until we realized our lengths might be slightly off.
This week, I will try to figure out why our material is not reacting according to Kevin's calculations despite the specs being the same as the previous year's material. The newly obtained thicker material are over-bending and the thinner material are under-bending. If we cannot figure out why, Kevin would need to create dies that are rough to the radius we need - therefore, they will not be precise and be a huge consumption of our time.

Hi,
during the break, I watched some SolidWorks tutorials and practiced it myself - about ten minutes a day for two weeks. I also submitted an updated Bill of Materials (that got approved) because the previous one was not good enough.
This week we returned from winter break and have already been given an urgent deadline of finishing our part of the project by the 22nd of March. I helped with establishing tentative deadlines for our team and followed up on a quote from CoastAluminum about the material we wanted to buy. Fortunately, the materials we purchased will be arriving as soon as February 8 - they also ship within the range of 1-5PM as we asked because nobody on the team can receive the shipment and thereafter transport it to the design center. I also helped take apart a piece of the track (was eventually going to be disassembled) so that we could see what we're working with.
In the coming week, I will be updating our Gantt Chart and solidifying deadlines with respect to other 12th scale teams as well.
