Subject: m9 t2 alignment job 

Continued with installation of target jigs:

1) Craned in equipment for alignment group.

2) Attempted to install target jig over B1 flange;

- Not enough horizontal distance south of B1 flange to install the target flange vertically and into place, jig must be maneuvered in side ways from the east of B1 into position.

- Spring eyes were designed such that after driving the taper pins into place the spring eyes were not being loaded due to a lack of allowing for spring compression. Design is being studied to fix this problem.

- B1 sighting flange was subsequently removed and one spring eye removed from the assembly (taper pins were left partially engaged in the top ear of the T2 M9 @70 Turns up (20 turns down)). Total amount of turns to drive down pins is 90 turns.

3) T2 M9 Q1 8" sighting jig was installed into place successfully

- Threaded pole used to install the 8" jig could not be unscrewed due to the pole tool securing nuts interfering with the pole used to install the pin drive (no clearance for tools). Poles are to be left in situ, screwed into their respective equipment until job is completed.

3) Alignment group sighted the T2Q1 target flange and the mushroom pad jig. They will continue on Monday with the B1 flange should the spring eye problem be addressed by then.
