(Sadecki, Bland, Buckland, Garcia)
Today we:
Attached the 4 Stay assemblies to the FMy (modification and recleaning complete), dog clamped them down and torqued the bolts to spec.
Verified magnet polarities of all magnets on ITMy.
Sorted, checked function on medm, and connected the 12 ITMy Top BOSEMs (model/code fixed).
Finished the ITMy cable routing.
Added ITMy Top Stage split lock collars.
And FINALLY,
Mated the ITMy Monolithic lower suspension to it's upper structure under the BSC8 ISI!
Attached the sleeve (with only a few bolts, because we only want the payload right now and will maybe remove it again).
Attached the LS cross braces.
Attached Vibration Absorbers (with only a few bolts as these will be removed and replaced again).
Again, the FMP tooling helped to ease the process. The mating screws for the Lower to Upper structures and the Sleeve are difficult to attach so we're considering looking into opening up some holes on the future units.

Tomorrow, the SEI crew will add ballast mass and rebalance the table. We will then work on lacing the cables up the suspension, reconnecting the wire segment between the UIM and top mass, and freeing the masses into suspension. Then we'll need to attach and align the BOSEMs before we can take transfer functions. A tall order for the last day of the week.
