BSC ISI Assembly Status (from end of last week to present)

(Corey, Jeff, Jim, Mitch)

Workspace Converted From HAM -> BSC

Over the last 3-4 weeks, the SEI Cleanrooms were cleared of HAMISI parts/hardware/tooling to make room for BSC work (this involved TONS of wrap/bag/tag & organizing).

Stage2:  Optics Table

Helicoils were completed last week (installation & tang-breaking) on the bottom-part of the Optics Table.  We are now waiting for fixturing to flip the Table over.  We will then install the Top-part of of the Optics Table

Subassembly Work Begins:  Enter Actuators & Lockers

Parts and hardware for the Actuators and Lockers have been unwrapped and staged in our Cleanroom racks.  Have begun helicoiling parts for the Large Actuator.  A few issues:  5/16-24 helicoils were inadvertantly installed on parts.  The correct 5/16-18 helicoils are being installed---a first fit-check shows that the bolts are really tight in these helicoiled holes.  We do not have a tool for installing #10-32 helicoils--it is on order.

This activity has enlightened us to the complexity of keeping track of hardware, and the importance of bagging/tagging parts correctly (and also paying attention to the names written on bags).  We are missing a couple of items, but we are addressing these issues as we go.

Stage0 Work

- Blade Posts are loosely installed (still waiting on big 1/2" socket to torque down bolts). 

- Torqued down Stage0 (wrench-tight) to the Test Stand via threaded rods/nuts (note:  one of the nuts was not installed because the threaded rod had bad threads).

- Level of Stage0 was checked---it is level to within 0.005"

HAMISI#3:  Moving Out

It has been decided we will postpone testing on this Assy.  (So, we'll need to put a few days into removing GS13s, payload, cabling, etc. on this Assembly.  It will eventually be pulled out and put into a storage container---once the container is modified for use).
