HAM 7 HEPI progress

HAM 7 had the chocks removed by Apollo on Thursday, allowing the support tubes to be adjusted. The crossbeam was slipped in between the two chambers and is now resting on the table secured to the opposite crossbeam. The housings have been moved onto the piers and the adaptor plates and weldments attached and will soon be ready to attach the crossbeams.

I've been running into problems with the bottom clamp where the threaded holes that support the clamp sleeve were not tapped deep enough. I may end up having to remove a lot of heli-coils and re-tapping the holes since other methods (such as attempting to tap the heli-coil) have ended up in many broken taps.
