3. Last Week’s Action Items Finish all machining Final Documentation

4. Machining Summary Made up lost ground. Base plates machined out of HDPE. Shaft-Hub connection. Flats and keyways on shafts. Aluminum Struts. Hand crank.

5. Documentation Summary Divide Focus and Conquer Domenic: CAD. Heather: Bill of Materials, project nugget. Mike and Matt: Executive Review and User Interface. Joey: Link to web and organization. Unite to edit and organize documentation. Integrated into the website.website.

6. Action Items Full Assembly of the Turbine Systematically assemble subsystems. Unite into entire turbine. Integrate circuit.

7. Action Items Cont. Develop a Prototype Display Presentation. Decide what points are to be focused on. Determine who will say what. Possible real time assembly. Outline as a group.

8. Concerns and Showstoppers Last week: Rotating Parts Resolved machined with advice from Leon. Sealed bearings Wear-in period. Run in drill press. Time is short! Expect complications. Solve them immediate as they arise.

9. Beyond the Last PDR Testing will crucial in the days that follow the turbine assembly. Small adjustments to the prototype may be made. A more accurate understanding of the concept will be achieved.

10. Conclusion Home Stretch Assembly First Presentation Second Testing Finally On Schedule Stay that way!
