Another issue-free extraction of the iLIGO passive internal Seismic Isolation System--Zac Rodney Chris EricA JimW CoreyG HughR

Again no issues.  This time we pre-positioned 122lbs on the Dome to level it up  and it was very much better.  Came off level and was much easier going on.

Bolt extraction from the Support Tubes was easy--everything as expected.

Dome/Door back on; all bolts in and nuts on, a few bolts on the door are torqued.  Rest of bolts need torquing.  Purge air is throttled back.
