[TowerTalk] G-1000DXA failure with lower mast clamp - follow up

[Barry N1EU]

I just wanted to post a follow up to this incident, where the downward
facing stock Yaesu bolts securing the G-1000DXA fell to ground.  I
took several steps to avoid repeating this near disaster and very
happy to finally have the SteppIR airborne again..

I was able to find M8X25 bolts with drilled heads
(www.probolt-usa.com/index.php/stainless-steel-flanged-hex-m8-x-1-25mm-x-25mm-race-spec.html).
 I used Loctite blue tape on the bolt threads, Nord-Lock wedge-locking
washers, and I lock-wired the bolt heads.  A close-up of the
lock-wired bolt heads can be seen at
http://n1eu.com/images/G1000_lock.jpg (the rotor is turned upside down
so the bolt heads seen are on the bottom when installed).

Thanks again for all the excellent advice I received here.
