BSC ISI Assembly Status

[Corey, Jeff, Jim, Stephany]

BSC#1 Assembly Work

Lots of shuffling took place today as plates were moved within the Staging Bldg and from the Vacuum Prep Warehouse.

Helicoiling and dowel pins were finished off on the Stage0 Top Plate.  The Top Plate was then installed & torqued onto the Bottom Plate.

The Optics Table was brought onto the Granite Table and now helicoiling begins!

BSC Work Area Space Creation

This section covers work to reassemble HAMISI#3 (i.e. clearing shelf space for upcoming BSC work). 

All of the Sensor Assemblies were installed.  It was determined earlier that two of the Sensors for #3 were bad, so new ones were swapped in for #3.  The new Sensors are S/N# 12029--->H3 & S/N# 12040--->V3.

During disassembly it was noticed that the small screws in the cable plugs which connect to the GS13 looked pretty damaged (their threads were really eaten up during assembly).  It was decided we don't want to use these screws, and want to just plug in the connectors.  But to do this, the damaged screws have to be pulled out because they don't allow the plugs to be connected.  This was done for all (6) plugs.

All of the Horizontal GS13's were installed. 

Note On Broken Tangs:

A few times during the reassembly of #3, rogue broken tangs have been found on several occasions (i.e. when you're installing a part, one finds that a bolt won't screw in---usually damaging the bolt).  This has happened while installing an Actuator and while installing a GS13.  So, eventhough we may be thorough, not all broken tangs are being accounted for.
