Summary ->  
Looking for large leaks -> We found a total of (7) leaking conflat flanges that will need to be addressed (>10-6 torr*L/sec typical).  In all cases, these were the large 10" and 12" joints and not the smaller feed-through joints.  We wrapped the leaking joints in RED UltraTape for indentification.  Also, both O-rings of the septum between HAM3 and BSC2 are leaking (inner high 10-4 torr*L/sec, outer mid 10-5 torr*L/sec), these are the O-rings on the BSC2 side which are integral to the septum plate.
