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. |

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 }}} |

Type B (Mark)
Report for week of 2/19
- We did TFs from the IM OSEMs.
- We secured the cables inside the BF, added the cap and anchored the cables from below the BF to the cap.
- We lifted the BF/... section with the load gauge adapter and measured the weight, which was about as expected.
- Based on the measured weight, Fabian prepared an 800 g set of masses for the top of the BF.
- We added the AF crossbars and the section of the SS below the SF and craned in the SF.
- We installed the SF-BF rod and flying saucer and suspended the BF/... section. With the 800 g placed temporarily on the BF, the SF keystone floated at about mid-range.
