1. Old Main Group

2. Design Issues There are no changes to the overall Design It will remain the way it is The Attachment Issue is resolved Going to screw on the tower to the flat part of the roof. The other parts of the roof will be fastened with “metal strips” and a pin.

3. Production Plan FAME Lab will be used for majority of work. Currently finalizing fixtures, and programs Machines to be used are: CNC Milling Centers and CNC Lathes Going to utilize Skytop Machine Shop to make precise cuts on some components. Final Machine Time per Old Main: 100 min. Total Time to Complete 20: 33 Hrs, 15 min.

12. Triangular Roof Sections

13. Material Ordered- 11/13/01 Outsourcing to SkyTop Machine & Tool, Inc. Water Jet Cutting Contract written Meeting for contract review First roof delivery/inspection All roofs delivered within 1 week of approval

14. Outsourcing Reasons In-house production difficulties Fixturing triangular stock Many operations- Difficulty maintaining required tolerances Not time efficient Water jet cutting can meet required tolerances and specifications Cost Effective

15. Base & Middle of Tower Fixture bars at a 45° angle in the specialty jaws and end mill the flat on each corner (4) Fixture on parallels and end mill steps (2) On the middle, pocket hole for clock mounting Base Process Plan Part 1

16. Top of Tower Drill hole 3 in center of stock for hollow portion of tower End mill flats and archway; rotate 45° and end mill flats plus ball mill columns (4) Contour dome and cutoff on lathe Top Process Plan Part 3

17. Current Status Material – Still waiting on material for front/backs and the triangular roof, as well as wood for bases. Fixturing – Constructing fixtures is complete. Tooling – All required tooling is available.
