There were several conversations this morning WRT outstanding general INS tasks that remain to be worked. The tasks Bubba and I had in mind were grouting at HAM5/6, removing aLIGO HEPI components from HAM7/8/9/10, and removing aLIGO feedthroughs from HAM7/8/9/10. The grouting work would be very dirty and very close to the SRs so Michael decided against that. Of the two remaining activities, the feedthroughs seemed the easiest to start. In conjunction with that work, Apollo will replace all Al blanks on H2 chambers with conflat blanks. Scott and Tyler spent the afternoon gathering materials.
