Activity report for weeks of 12/26 and 1/2
- 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.
