Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

- Polycarbonate vs polypropelene for Thein design. (2/13 In Person)
  - decided on polycarbonate. Easier to use.
- How much safety does the sponsor want? Life time of the trimmer? (2/13 In Person)
  - Sponsor was unable to come this week in person. He will be consulted next week at the meeting

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

- Work on presentation skills (2/13 in email from Pedro)
  - Will practice the presentation more before giving it

Risks and Areas of Concern

- making the adjustable nozzle mount is tricky to design
- mounting the nozzle on one side vs two
  - one side is easier to design but might be more susceptible to fatigue failure.

Resources or Information Required but not Available

Schedule

- We should know if the trimmer works as intended by the end of the week.
- We should have the adjustable nozzle mount design done and ready to be printed by the end of the week
- We should know how the new nozzle design works by the end of the week.
