* Hirata-san produced a near-final Inventor assembly of the BS on the assembly frame, for use in writing the assembly procedure. * Includes assembly frame modifications suggested by Mirapro, including feet, wheels, lifting eyes, thicker crossbars under BF, IM etc. * Includes final rail system except for interface plate to mirror box. * Includes full PI with ballast masses. * Includes cable clamps. * Includes correct versions of BF and SF. * Includes new BF pushrod parts to work around different placement of blade screws in new version of BF. * Includes cleanbag support bars. * Includes key parts of mirror box (enough to check for interference) - needs more work. * Does not include various invisible duplicate assemblies that had been present due to cut and paste. * After a few more improvements, the new assembly will be sent back to Mirapro. * Got status from Miyakawa-san on electronics - there should be enough of the boxes AEL is supplying. * Cleanbag design was finalized; Aso-san is ordering: [[attachment:160419-チャンバーカバーⅡ型.pdf]] * Quote for flags and prisms was received, but expensive - may drop rigid flag design. * The mirror box will require only very minor modifications for flags and prisms - Tatsumi-san will arrange immediately. * Fabian worked on understanding Sekiguchi-san's control design to help decide optimum wire thickness. * Mark worked on install procedure and schedule. * Takahashi-san enquired with NIKHEF about oscillator cards for LVDT chassis - lead time would be 3-4 months. |
