[TowerTalk] torque arms vs. pier pin

[Richard Boyd]

>From what I've heard a pier pin base is a more effective way of addressing
unwanted torque, twisting, stress on welds, etc. in a tower...in severe
winds let the tower turn as it will on a pier pin.  Of course it won't turn
far with the guys restraining it, but much or most of the torque on the
stress will be handled harmlessly.

The main and/or only disadvantage of a pier pin base, as I understand it, is
the necessity of temporary guys during installation of the first few
sections, until you get to the first permanent guy level.  73 - Rich, KE3Q

As always, I reserve the right to be wrong.
