  * Fabian took photos of the cleanroom in the ATC to help decide whether it is a good place to assemble PIs for Type A/B.
  * Hirata-san ordered and received wire for the BS and RM (will be cleaned 7/19).
  * Hirata-san received remachined locking parts for the IM (will be cleaned 7/19).
  * Hirata-san ordered additional Misumi parts to be used with the IM locking parts.
  * Fabian and Hirata-san weighed the masses that they've been constructing in the cleanroom and found a 600 g discrepancy from the Inventor (too light) for the IM.
  * Hirata-san ordered a medium-capacity scale to weigh the masses of the individual parts more precisely.
  * Hirose-san and his team successfully removed the misglued prisms from the dummy BS.
  * Fabian travelled to Kashiwa and removed most of the glue from the face of the dummy BS (where the flags had been). There is still some adhesive remaining on both the face and barrel, which will require more work and a second trip.
  * Shoda-san took a suitable segment of geophone noise data for analysis. Fabian will track down the calibration factors.
  * Akutsu-san provided a set of cleanroom gear (shoes only slightly too tight!) for use by Mark this week. And Sakamoto-san sent another set from Kamioka to Kashiwa.
  * The RM, IM and IRM were weighed, and wrapped/packed for shipment to Kamioka.
  * Mark made a checklist of all the parts of the BS mirror box and gluing jig, to help with collecting the parts from Kashiwa.
  * Hirata-san removed the remaining glue from the BS primary and secondary prisms, as well as the prisms removed from the PR hanging test mirror.
  * Fabian designed an extra 600 g of trim masses for the IM and Hirata-san made drawings and ordered them. The design allows for the masses to be added even after the dummy optic and RM have been hung, so it should not delay work.

   * Mark worked on the schedule, making the next few weeks more realistic and incorporating the new plan for the SR RMs (the test will be used for SR2 but two more will be made from scratch next financial year).
