==== Report for week of 12/25 ====
 * Hirata-san got the L-brackets machined and washed, and installed them on the IM ring bars.
 * Shoda-san recovered the BS from the power outage on 12/25.
 * Miyakawa-san fixed an issue with the SR2 RTM which had prevented it from running.
 * Shoda-san, Hirata-san and Kozu-kun weighed the IM without ballast masses, and then added the lower masses and installed the IM on the assembly frame.
 * They cleaned the assembly frame and installed new jack receptacles on the load gauge adapter.
 * They installed the winch system on the IM, and inspected the clamp pieces for possible scratches.
 * They ran cables for the SR2 steppers and OSEMs.
 * They calibrated the BF LVDT.

==== Report for week of 1/4 ====
 * Mark fixed a number of errors with the Type B screens.

==== Report for week of 1/9 ====
 * We weighed the mirror in its box (and later the empty box), and the RM.
 * Fabian worked on the SR2/SR3/SRM mass budget and did an inventory of spare ballast masses.
 * We hung the SR2 and RM.
 * We assembled the bottom section of the security structure below the RM.
 * We cabled the RM OSEMs up to the IM.
 * Hirata-san gave up on waiting for a third quote for the blades and blade parts and started the ordering process.
 * Hirata-san got rod cable clamp parts from Takahashi-san and worked on drawings for the improved BS vertical and yaw adjusters.

==== Plan for week of 1/15 ====
 * Fabian at Mitaka Monday 1/15 to inspect filter load test items.
 * All at Kamioka.
 * Shoda-san to work on readjusting PR3 and also making OSEMs.
 * Enzo and Kozu-kun to help with making OSEMs.
 * Test RM OSEMs.
  * Check coil driver is successfully driving current.
  * Time permitting, do TF test from coils to optical sensor.
 * Suspend IM using load gauge adapter, and check/adjust total mass and balance.

==== Plan for week of 1/22 ====
 * All at Kamioka
 * Bring in BF and suspend IM.
 * Route final RM/IM cables up to below BF.
 * Recheck/adjust total mass and balance.
 * Route selected cables to flange.
 * Test IM picos and BF yaw pico.

==== Plan for week of 1/29 ====
 * Enzo at Mitaka 1/29 and most of 1/30, then vacation.
 * Kozu-kun away.
 * All others at Kamioka.
 * Build IRM around IM.
 * Cable/test/adjust IM OSEMs.
 * Time permitting, do TFs from IM OSEMs to themselves and to optical sensor.
