| * 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. |
* Hirata-san: * Made cables for LVDT. * Made drawings for new wire clamps. * Asked ATC for manufacturing parts.(and modified drawings.) * Asked quotes for SDC coating for hooks. * Sent packing tools for BF. * Talked with i-ject about quotes for payload. * Mark and Fabian at Kamioka (plus Enzo for 2 days): * Finished rebalance of IM * Reinstalled IRM, adjusted OSEMs * Replaced broken Type 3 cable on IM-H1 OSEM. * Fixed issues with k1visbs real-time model. * Started TFs from IRM OSEMs to IRM and IM OSEMs. |
