HAM6 closed

After the ISC crew were finished, Jim unlocked the ISI and made a small adjustment to it's balance.  I wiped a few of the surfaces of the ISI and chamber that I could reach near the door.  I placed a witness plate on the ISI table in the middle of the sea of ISC mirrors nearest the east side of the table.  Kyle, Gerardo, Bubba and I then tacked the door on with 4 bolts.  Kyle turned off the purge air.  Dan/Keita and Jim are running OM/OMC and ISI TFs to see how we fair for pumping down tomorrow.  We're not yet out of the woods.  TBC...
