Dear Mark,

I did for Type-B as below,
・modified parts list and screw list for Payload.
・sent lists to i-ject and asked for quotes.
(But we need to send latest list again.)
・made drawings for some jigs and some parts for payload.

For PR
・searched glueing 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 send them to Kamioka.

Best regards,
Hirata

Hello,

Succinctly, it is as follows:

1. Mechanical design:

    a. Pull down system to fix the power recycling IM to the EQ stop.
    b. EQ stop for the BS recoil mass.

2. Checked assembly PR/SR drawings. There were few corrections/changes.

3. Checked fastener list. There were few corrections/changes.

4. Checked component list for the manufacture order. There were few corrections/changes.

5. I helped in searching for the PR mirror box missing pieces at Mitaka.

Regards,

Fabian

  * 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.
