It was a long day, but the HAM1 ISI is in the chamber. Mitch pointed out first thing this morning that the install fixture was still in the "short" configuration, with 2" spacer pads on the under side of the middle stand. We partially disconnected the I beams an swapped to the "tall" configuration, squared the I beams up to the chamber, including checking the height of the feet (procedure says 3", but could vary), centering on the HEPI piers with a plumb bob, checking I beam level with a bubble level and checking the vertical gap between the tightest point between the I beams and the chamber door, which the procedure recommended be 1.5". We then brought the ISI container into the LVEA, then realized the pallet jack was too close to the container to open the latches for the lid. We put the container on cribbing, adjusted the pallet jack then took lunch. After lunch, we took the lid off the can, flew the ISI over to the install cart by HAM1 and made a first attempt to slide the ISI in, at which point we realized the Stage 0 of the ISI would hit the tips of the HEPI springs. After much deliberation, we set the ISI back down on the cart and used the crane to lift the install fixture (I beams and stands) and extended the padded feet as muc has possible. We had to use the fork lift on the -Y side of the chamber, as the clean room blocked crane access. Clearance between the outside edge of the I beam and door was now about .5" and the feet were 4" above the floor. At this point the ISI sailed over the HEPI springs and we were able to proceed with the ISI install as normal, smooth sailing. 

First two photos show the height of the feet and the clearance between the I beams and the chamber. Last one shows the clearance through receiving with the container, as we brought the ISI in. Others got pictures of other points and I hope will add. 

We still have to pull the install fixture, then we can start plugging stuff in.
