Joint repair continues.

Leak Check:

- Local leak check performed around area of T2, M9-Q1. All seals other than T2 Q1 were leak tight. Largest source of leak was the T2 Q1 joint area.

- Leak check done in quadrants around joint, response times were <2 sec of applying helium. Leak detector also responded when He probe was near joint (before actually applying He).

Video and Physical inspection:

- Bottom weld lug bolt found in tension/captive (ie. not free to move). Confirmed static by poking bolt. (Videos of this in RH group folder).

- Top weld lug had > 0.2" of gap.

- East and West pins seen leaning slightly toward North (toward Q1).

Loading Test:

At 13:30 a load test was performed to observe the effects of loading nearby blocks around T2 (see photo). Two 12 x 6 x 3 shield blocks were stacked one on top of the other and vacuum was observed, one then the other. There was no observable effect on the vacuum each time. Bottom weld lug bolt was still frozen when poked.

Blocks were replaced to their original locations once test was complete.

The T2 volume was vented at ~14:15 in preparation for disassembly to be performed on Monday.
