  * Need to hand-make geophone cables
  * Need to make longer versions of BF-PI and SF-PI cables (3.7 m and 2.5 m)
  * Need to check OSEM cables have same flip for flexicircuit as for PRx.
  * Asked Miyakawa-san for status on AEL items, especially stepper driver.
 * Compensation masses for RM/IRM ordered, expected 4/29

 * Hirata-san drew up flags
 		  * Type B Past Week Summary
  * Fabian did inventory of parts/fasteners for dummy BS, RM, IM and IRM - almost all at Mitaka. A handful (picos, pico drivers) will be brought back from Kamioka.
  * Fabian continued work on Mathematica and Matlab models of the BS and control system. He now gets much better agreement after correcting discrepancies between the parameter sets.
  * Hirata-san worked on organizing:
   * Checking Mirapro assembly frame drawings
   * Ordering missing screws and small items (screws for dummy mass, fine pitch M8 for RM)
   * Work platforms and clean booth second floor arrangement.
   * Load gauge adapter and associated parts
   * Possible fall-back plans for the rods connecting the security structure to the PI.
   * Design for additional trim masses (existing design had no provision for adding/removing).
