  * Hirata-san made a 3D assembly model for SR2 and added the optical design.
  * Hirata-san worked with Uchiyama-san to solve the 90° rotation problem. It turns out the "box" part with the pistons can be rotated, so we can build the SR2 according to the original design.
  * Hirata-san investigated the puzzle of the BF-IM maraging rods, where the 2D drawings and 3D CAD do not agree. Fortunately the actual parts seem to agree with the 3D CAD.
  * Hirata-san washed 3 OSEMs (last of initial 10 for BS) and parts for two BFs (for Type A). He moved the BF parts into the clean room and will assemble them with ATC staff from next Wednesday 9/7.
   * Placed safety rails, rearranged floor panels, cleaned new floor panels, and otherwise improved safety.
  * Hirata-san:
   * Made new 3D models of the maraging rods for PRx and SRx
   * Made new collet design for PRx and SRx.
   * Made new IM flag design for PRx and SRx.
   * Washed lots of Type A BF parts and OSEM parts.
   * Measure some BF part dimensions.
   * Pre-assembled parts for BFs.
Line 18: Line 22:
  * Longer cables for BF->PI and SF->PI - RECEIVED
Line 20: Line 23:
  * Decide position of BS rack - DONE
Line 22: Line 24:
   * Part "disk security" top has to be modified - screw positions do not match.
