 * Hirata-san produced a near-final Inventor assembly of the BS on the assembly frame, for use in writing the assembly procedure.
  * Includes assembly frame modifications suggested by Mirapro, including feet, wheels, lifting eyes, thicker crossbars under BF, IM etc.
  * Includes final rail system except for interface plate to mirror box.
  * Includes full PI with ballast masses.
  * Includes cable clamps.
  * Includes correct versions of BF and SF.
  * Includes new BF pushrod parts to work around different placement of blade screws in new version of BF.
  * Includes cleanbag support bars.
  * Includes key parts of mirror box (enough to check for interference) - needs more work.
  * Does not include various invisible duplicate assemblies.
 * Got status from Miyakawa-san on electronics - there should be enough of the boxes AEL is supplying.
 * Cleanbag design was finalized; Aso-san is ordering: [[attachment:160419-ﾁｬﾝﾊﾞｰｶﾊﾞｰⅡ型.pdf]]
 * Quote for flags and prisms was received, but expensive - may drop rigid flag design.
 * The mirror box will require only very minor modifications for flags and prisms - Tatsumi-san will arrange immediately.
 * Fabian worked on understanding Sekiguchi-san's control design to help decide optimum wire thickness.
 * Mark worked on install procedure and schedule.
 * Takahashi-san enquired with NIKHEF about oscillator cards for LVDT chassis - lead time would be 3-4 months.

 * 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.

 * 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.
