  * Hirata-san:
   * Modified parts list and screw list for payload.
   * Sent lists to i-ject and asked for preliminary quotes.
   * Made drawings for some jigs (PR hold-down jig) and some parts for payload (PR/SR wire clamps with disposable jaw pieces - improved version with disposable pieces in both primary and secondary clamps).
   * For Type Bp:
    * Searched for PR gluing jigs.
    * Washed and assembled recoilmass base for mirror hanging jigs, and sent them to Kamioka.
    * Washed additional masses for IM and sent them to Kamioka.
   * For others:
    * Washed IMMT plate and sent them to Kamioka.
  * Fabian
   * Designed a pull down system to fix the PR IM to the EQ stop (similar to the SR one).
   * Worked on design of the SR assembly frame. As hoped, the SR version can be almost identical to the BS version.
   * Worked on design of additional trim mass (≈18 kg) for the BS BF.
   * Checked assembly PR/SR drawings. There were a few corrections/changes.
   * Checked fastener list. There were few corrections/changes.
   * Checked component list for the manufacture order. There were few corrections/changes.
   * Helped in searching for the PR gluing jigs.
  * Mark
   * Started design of SR assembly frame (but then passed it to Fabian).
   * Worked on task lists and schedule.
 * Plan for 1/10-13
  * Mark and Fabian at Kamioka:
   * Finish rebalance of IM
   * Reinstall IRM, adjust OSEMs
   * Replace broken Type 3 cable.
   * Do TFs from IRM OSEMs to IRM and IM OSEMs.
   * Cable up and test BF LVDT and fishing rod (time permitting).
   * Disconnect BF and ship back to Mitaka (time permitting).
  * Hirata-san:
   * More SR procurement.		 ==== Plan for week of 3/26 ====
