Greg & Mitchell Locked the ISI & used the crane to lift the four 150lb Keel Mass Stacks and placed eight 1x1x1/4"thk viton pads, two under each corner of the stack.

Meanwhile, Jim & I unbolted the six Optical Table Mass Stacks and replaced all the viton with approved material.  We also added a second metal washer under the shoulder of the Shoulder Screw to compress the viton a little less.  Now we'll see how those peaks look.

Since the ACB needs a little more tweking, we left the ISI locked.  HEPI remains unlocked.
