A new, smaller, fixture is needed to place the polished mirror in the cell for Tucson testing and finally for operations on the mountain. If steel plates are added to this fixture, it serves as a dummy mirror to test the mirror support system. This fixture was not in the MOU estimate for the project. This sealant has good mechanical properties, but it does not adhere well. 6093 adheres well but there may be problems with its mechanical properties.
Tests are ongoing.
The load continues to move on schedule. Tom McLellan, TIW Vice President, and the TIW machinist will travel to Votaw to oversee the transfer from the truck to the large milling machine. The cell will be machined in the nadir pointing position. J.T. Williams and Tom Hoffman will travel to Votaw to review the machining plan. We must specify, design, and procure this system by August 95.
