After the HAM3 cleanroom was pushed as far north as possible, the curtains were modified to closely interface with BSC2 and provide clean space for the spool replacement. The small spool piece was inserted  and attached to the BSC2 flange. Next, the large spool piece was inserted and attached to the small spool piece. The large spool piece is very close to the HAM3 flange. Once the hard cover on the spool piece and the soft cover on HAM3 are removed, the bellows will be extended so that the spool is married to the chamber. I expect that all spool and appropriate flange bolts will be torqued before the Apollo crew leaves for the day. That gets us through #11 on the checklist.
