[TowerTalk] Plumbing a tower

[David Gilbert]

Three inches out of 100 feet also requires an accuracy of 0.3 inches for 
a plumb bob string hung from a 10 foot section of tower.

Three inches out of 100 feet calculates out to be a total angle of 0.14 
degrees.  By that criteria, the 0.1 degree resolution of the digital 
angle gauge I used doesn't seem like that much overkill.    I guess I'm 
just one of the particular ones ...
