 * Type B Past Week Summary
  * Mark, Fabian and Hirata-san cleaned glue off the dummy BS, attached Akutsu-san's new SS mirror plates, reglued the flags and prisms, and removed the gluing hardware, so the dummy BS is ready for shipping. Tatsumi-san's refinements to the tooling (especially the new flag holders) worked very smoothly. We were more generous with the glue and much more careful with the alignment of the prisms to the barrel, both during rehearsal and the final gluing.
  * Mark wrote up the gluing procedure as a new document [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5505| E1605505]]. (The original plan was to do an addendum to Tatsumi-san's PR gluing procedure JGW-E1504248, but there was too much material.)
  * Hirata-san organized with Takahashi-san to get the BS payload masses shipped to Kamioka. They will go in an air-ride truck on Wed 8/17 together with a load of Type A stuff, and will arrive early on Thu 8/17.
  * Hirata-san measured another standard filter.
  * Fabian worked on the payload assembly procedure.
  * Komori-kun, Kuwahara-kun and Akutsu-san calibrated an initial batch of 7 wide-mouthed OSEMs. They will be shipped to Kamioka on Friday.
 
 * Type B ongoing issues
  * OSEMs
   * First batch of 7 ready for shipping.
  * Longer cables for BF->PI and SF->PI.
   * Connectors RECEIVED, cables being made.
  * Lower breadboard stuff
   * Installation to be incorporated into the procedure document. Mark/Takahashi to discuss.
  * Documents
   * BS Assembly Procedure [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235| E1504235]], [[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder,webloc|E1504235 draft]]
