Penultimate mass put into lower structure and moved into the welding area for alignment. Penultimate was hung on wire loop and pitch checked by eye against the structure. 440 stops were slid in and PUM sat down on them. Various earthquake stops were added around both PUM and test mass. PUM was aligned in pitch and roll. Test mass aligned in pitch, roll and separation from PUM. Looks to be pretty much ready for welding on Monday after doubling checking pitch and separation.
