Hi,
this week I discussed and settled with the Track Manufacturing team that they will be handling the bends of the track's corners (which they have completed). I completed most of the PowerPoint and started the final report. The final report first draft is due on Friday, so we will continue to work on it throughout this week. I have been e-mailing Eric, Michael, and Neil the bill of materials which we have completed for the most urgent material we needed: PLA filament. Eric approved of it and we purchased it for only $93 on Amazon which should be enough material for all 30 castings of our U-bracket. The bill of materials I completed was rather sloppy since we needed the PLA filament ASAP, but I will be updating it with all of the company's quotes tonight. This week was slightly more relaxing since it was Thanksgiving weekend and we were waiting for approvals.

Hi,
this week I was responsible for finishing a rather urgent Bill of Materials which I did and e-mailed to the three people: Eric Hagstrom, Michael Kemp, and Neil Shankar. They are responsible for approving our budget which will then need to be approved by the A.S. It was an urgent bill of materials because we decided to 3D print all of our brackets which our teammate Jezreel has offered to do for us, free of charge (of course, not including the 3 orders of PLA filament which would cost around $75). I also dimensioned the overall dimensions of the track to make sure it fit the given area when presenting at Paseo Prototyping and Maker's Faire which was within a 15 by 15 feet area. Our track currently sits at about 13 by 13 feet as shown below. On Friday, Jez and I went to see VanderBend to talk about our quote and future meet-ups and were given a tour. Having gone to VanderBend, we got to see how they do things different from us and we were given a little information as to how the track manufacturing team and us should tackle the bending issue.

Hi,
this week I have been remaining in contact with Kearny Foundry and about making a mold for our bracket (picture shown below). The only problem with the mold is that they would be unable to create the press fit and holes of the bracket (which would require for us to machine ourselves). I spoke with Kevin (from the manufacturing team) and we could make a station and/or mount to repeatedly tap holes and make the press fits consistently. Just this morning, however, I finally obtained a quote from them and they said: $940 for the mold and $16.30 per heat treated casting which totals $1429 and would take about four weeks. I told this to the group and we decided that we might just 3D print the brackets instead with a 60% ink fill PLA filament approximating $60 and roughly three weeks. 3D printing would save time, money, and solve the issue of creating repeatable press fits and holes.

Hi,
this week I focused on turning all SolidWorks parts into drawings and pdfs for the sake of organization, submitting to companies to request for quotes, and uploading to Google Drive for other teams to stay updated. Two of the fifteen drawings I finished this week are shown below. I was also responsible for getting a quote from Kearny Foundry; we should have a quote by next week just in time for the Bill of Materials deadline. We are slightly behind in terms of getting a quote because they had a ton of questions and since it was my first time asking for a quote, my e-mail was not extensive enough and I have been e-mailing Kearny for several weeks as a result. I have also been talking to Kevin from the 12th scale Track Manufacturing team about their process of creating a tool to bend aluminum and his team has been making great progress. We might just be able to manufacture all of the stuff in-house if the dimensions remain consistent.

Hi,
this week I did not do much after our Presentation. I have simply been shooting e-mails back and forth with Kearny Foundry, trying to satisfy their questions for us so we can get a quote - so, yes we are still waiting for a quote. We need to speak with the other teams about a more definitive date for all going to Vander-Bend together. There is little left to do in the design process; we are all figuring out manufacturing process currently. This week has been a busy week for me due to midterms and other projects.
