At Kamioka (Mark, Fabian, Enzo, Hirata-san):
 * We disconnected the in-vacuum and in-air cabling from the feedthroughs.
 * We removed crossbars below BF and SF.
 * We set the SF damper to 4 mm clearance.
 * We adjusted the jacks to nominal height.
 * We removed the geophones and PI yaw stepper for craning.
 * We craned the suspension into the tank, and hooked the LBB Cu ring.
 * We replaced the geophones etc.
 * We unlocked all but the IP and adjusted the jacks until the pendulum was centered in the security structure.
 * We unlocked the IP and adjusted to to center with the jacks and fishing rods.
 * We craned the vacuum tank lid+ring back on, and then removed just the lid (only).
 * We unclamped the LBB damper rings and removed the spacers.
 * We removed the blocks and shims supporting the LBB, inserted the long screw feet and hooked the LBB to the Cu damper ring.
 * We added 2*31.5 kg of ballast to the LBB, which got the blades to the point where firm pressure would depress the tips.
 * We reconnected the in-vacuum cabling. In ≈15 places we opted to omit the Type 1 cable and use a F-F gender bender.
 * We reconnected all but four of the in-air cables.		  * Mark created screens and a macro.txt file for the SR2 and linked to them from the VIS screen.
 * Enzo and Mark did a new overview screen for the BS.
 * Enzo added DIO cards to the rack and connected them to the coil drivers.
 * Fabian and Kozu-kun finished assembling the IM and tested the picos over their full range.
 * Mark and Hirata-san configured and aligned the assembly frame and optical table and craned in the IM ring.
 * Hirata-san noticed some oxidization on several of the L-brackets that will hold the IM horizontally, and we should get them cleaned or machined, but we can probably continue with hanging the system in the meantime.

==== Plan for week of 6/26 ====
Mark and Enzo at Kamioka:
 * Double-check where gender-benders were used.
 * Finish connecting in-air cabling.
 * Debug all cabling.
 * Work with Simon to set up LSOL.
Fabian at Mitaka:
 * Design final ballast masses for IM, BF and SF assuming no BF rebuild (needs to be adaptable).
 * Check all items for BS flag/prism gluing are available (prisms, flags, jigs, mirror box, glue, scale, mixing tools etc).
Hirata-san at Mitaka:
 * Do new 3D CAD:
  * BS Test Hang build, with top of tank, full suspension, and LBB damper all reversed.
  * Final BS build, as above, but with everything BF down rotated back to original.
   * In-tank version.
   * On-assembly-frame version. (Adjust jack positions if possible, or leave for Mark to do.)
  * SR2 on BS assembly frame. (Adjust jack positions if possible, or leave for Mark to do.)
==== Plan for week of 12/25 ====
 * Power outage 12/25.
 * Mark, Enzo, Fabian vacation
 * Shoda-san, Kozu-kun, Hirata-san at Kamioka - Hirata-san from Tue, others TBD.
 * Recover after power outage.
 * Create SR2 real-time model.
 * Install new jack receptacles (in SR3 area, second floor) on load gauge adapter (SR2 area, second floor). (Hirata-san)
 * Weigh IM (per Fabian's note in the paper log).
 * Remove L-brackets from bars on IM ring - send for cleaning/remachining.
 * Setup OL for checking pitch of SR.
 * Wipe/blow dust off SR2 frame.
 * Crane IM into frame.

==== Plan for week of 1/9 ====
 * Mark, Fabian, Enzo, Shoda-san at Kamioka Tue-Fri.
 * Hang SR and RM.

==== Vacation Info ====
 * Mark 12/22-1/3
 * Enzo, 12/21-12/27 (but ''not'' 12/28)
 * Fabian 12/22-1/5
