BSC #1 Stage 0 Top Plate

This plate was placed on the granite table for pre-assembly work.  1/4"-20 & 3/8"-16 helicoils were installed on this plate.  Unfortunately, we did not have a tool to install the 5/8" helicoils.  Additionally, we also installed dowel pins.

HAM#3 Re-assembly

Last week one of the eyebolts installed on the Optics Table was found to be stuck in the table.  Today a 6' bar was used to attempt to turn it out and this 3/4"-10 Eye Bolt ended up breaking in the table.  There is probably ~1" Class B "threaded rod" now stuck in the Optics Table.  Initially thinking we would pull out this Table and swap it, ~130 of the bolts were pulled out of the table, but in this time, it was decided that we would probably keep this Table in place (so the ~130 bolts were re-installed).

The eye bolts we use for lifting plates have tons of thread (~2"), and each thread is an opportunity for galling a part in a plate.  In the future we should use nuts (as spacers) on these eye bolts, or cut these eye bolts down to a useful and safer length.

Since we decided to proceed with this Optics Table, we can now continue with assembling HAM#3 (install  Actuators, Sensors, Walls, weight for GS13's, release Springs, etc.).
