HAM 9 & 10 install progress

Working with Scott and Ed, HAM 9 was leveled and each support tube brought between 24 and 20 thousands of an inch above their final value to deal with expected settling. HAM 9 is now ready for actuator installation and final positioning of the springs.

HAM 10 has had the East end cross-beam installed but not put into final position yet. The West end cross-beam will be loaded on first and then both will be squared up and put into nominal position with relation to the support tubes.

A few of the clamp caps have required modification. The holes were not tapped deep enough for a 2-d helicoil causing the end of the helicoil to bind with the bolt. Thanks to a great idea from Tyler, tapping the helicoil shaved down the tail enough to have the bolt move through smoothly.
