At Mitaka and Kashiwa (Mark, Hirata-san, Fabian, Enzo): * We glued magnets into their holders. * We did a walk-through of the gluing procedure at Mitaka and discovered that the secondary prisms were missing. * We took the mirror box and gluing tools to Kashiwa to do as much of the gluing as possible. * Hirose-san applied First Contact to the BS and he and Kieran moved it into the mirror box. * We practiced putting sapphire prisms on the BS but didn't apply glue. * We tried the magnet gluing jigs designed by Aso-san and found two major issues: the overall length was about 25 mm too long, and there was no adjustment to allow for the wedge. * We designed a simple modification to the jigs that hopefully would be trivial for the ATC to do: the jigs will be cut in half and the bottom section will be mounted with adhesive on an 11 mm rod that slides in the central hole of the top section. Thus the top half can be screwed into the existing recess, and the bottom half with the magnets and glue can be allowed to drop about 3 mm onto the face of the optic. Hirata-san worked with ATC to get this done and it should be ready today (Friday 7/7). * Hirata-san also got ATC to make some jigs to hold the old 5-mm prisms so that they can be ground down to 3 mm to replace the missing ones. Hirata-san will do the grinding himself today (Friday 7/7/). * We decided to continue the gluing work at Kamioka, so we brought the BS back to Mitaka and will ship it on to Kamioka next Tuesday. * Hirata-san did a version of the 3D CAD with the as-built BS Test Hang configuration. ==== Plan for weeks of 7/10, 7/17 ==== Mark, Enzo mostly at Kamioka. * More TFs. * Receive BS at Kamioka, do gluing if possible. * Document LVDT driver rebuild and other changes. * Learn how Miyo-kun's pico driver software works and make fixes/improvements. * Design/install matrices, blend filters and damping filters. * Finish tidying rack and labeling cables. * Add temporary ballast to LBB and find total required. * Try rearranging arc weights to make room for magic wand. * Start on creating SR3 rack. * Preparation for BF rebuild.
