==== Past week report ====
 * Hirata-san:
  * Worked on the PR optic removal jig.
  * Worked on getting modified quotes for PR/SR/BS parts.
 * Enzo-san
  * Worked on getting his drivers license.
  * Worked on getting familiar with the Type B circuit diagram.
 * Mark, Fabian (at Kamioka):
  * Tried different strategies for getting the IRM-IM EQ stops and IRM OSEMs to line up simultaneously.
  * Realized that the main problem was that the pitch of the BS had changed relative to the IM (presumably due to slight slippage of the wires) so the IM had to be pitched up by 16 mrad to get the BS pitched slightly down (4.7 mrad).
  * Took the sides off the IRM to get access to the clamps and tightened them to prevent further slips.
  * Rebalanced the IM to be level in pitch (and roll).
  * Reassembled the IRM and aligned the IRM-IM EQ stops - this time it was easy.
  * Adjusted the IRM and RM OSEMs to mid-range.
  * Got Kokeyama's new real-time model working and started TFs.
  
==== Plan for coming weeks ====
 * Mark and Enzo come to Kamioka and work on rack and cabling.
 * Fabian works on design, including SR assembly frame.
 * Hirata-san works on procurement.		 ==== Report for week of 3/19 ====

 * Finish tuning of BFs (Hirata-san++).
 * SF check (Hirata-san++).
  * Check load capacity.
  * Check fit of caps.
  * Add cable clamps to bases.
  * Add cable clamps and Cu segments to caps (only if they fit well).
  * Cable LVDTs and steppers.

==== Plan for week of 4/2 ====
  * Glue SR3 (if available)
  * Build 2xIM, 2xIRM (if parts available - due 3/30)
