HAM 9 HEPI Install

Both the crossbeams for HAM 9 have been installed despite the fights for crane time. With the aid of Ed and Scott we were able to pass the crossbeam under the beam tube first by picking with a cradle lift from the center of the tube, then setting the crossbeam down on stands and re-picking with the spreader bar. For some reason the HEPI foot took even more adjustment to bring into alignment than usual. The North end frames are a little south of an optimal Position (a few 32nds of an inch).

Remaining is to install the clamps on the frame and torque the south end to spec. Afterwards the clamps will be torqued around the support tube and hopefully the support tubes can be shot and brought into nominal position.
