RH beam line work for UCN continues at T1.

- Attempted to scrape t1 flange, narrow scraping tool does not fit into space because of the headers on the water system of the magnet. Decided to continue installing blanking plate with rubber anyway.

- Installed blanking plate between T1 and M13Q1 with rubber.

• Q2B1 joint was closed up and pins driven down to anchor the vacuum box in place.
• Joint was opened and then blanking plate was inserted into place against T1 flange. Q1Q2 vacuum chamber was extended to preload the plate.
• The flange needed to be adjusted into place slightly and then the pins driven down to load the plate further where it then needed to be pried into position. After this the pins could be driven down completely.
• Bolt stops on the Q1 flange that brace against the magnet were seen in video inspection. Also bolt lugs like as on the M9 and M20 vacuum box were seen although without bolts present in them.

- Q2B1 joint was disconnected again. Spring eyes are still not fully clear enough to lift away B2 magnet.
