Announcements

• Trial workday is this Saturday from 1-5ish.

  • We will still start workday at 9:30am. We will all meet at ETC and leave for Pickle in the morning. Drivers will return to ETC by 1 to pick up recruits.

  • Reminder that we will be discussing setting a track width, wheelbase, and CoG location in the morning (and work on architecture brainstorming)

  • If you have a car please bring it if you can to reduce the amount of back and forth

  • Wear your solar shirt if you can

• Reminder to have material ready to set a track width, wheelbase, and CoG location by Saturday; architecture brainstorm ideas by Sunday

• Daybreak disassembly date still undetermined (either Saturday or Sunday). What is the purpose of disassembling the car this early?

  • Decision: Postpone disassembly

• Can we meet this week to have a case study of Electric’s assembly management, and how they use dynamics and frame reference sketches

  • Decision: Replace time saved from postponing disassembly with this meeting

Aeroshell Mold Manufacturing Plan

• Used Daybreak dimensions to determine mold dimension

• Split mold

  • Pros

    • easier for mold release

    • wouldn’t have to glue

    • main benefit is for demolding and sanding

  • Cons

    • Would potentially have to cut down foam stock — we are given standard sizes

    • We bought the foam that the foam people got from the supplier—even larger size

    • We might need extra prep to cut foam

    • Buy more stock than you need and roughly cut it?

    • We got our foam and it was a special order because we didn’t need it cut, sawyer didn’t do any work to prep it

    • Sawyer only picked up the foam from the pallet and then machined it

  • This is a mold prep solution

  • Attaching the molds together isn’t that difficult, mold is pretty stable

  • Composites is really rough and hands on, we can use dowels and straps to line things up, no force is pulling them apart

  • Timeline in which we receive molds must be considered. You will not get molds at the same time.

  • Do we wait and get a quote for both?

• Top shell double or part of bottom shell

• like c[] (3 parts) or c] (two parts and wider base)
