Hi Dick,
I'm not trying to critcize your critism either, but I am not sure I am
seeing all you are seeing in the Rohn book. Regarding the use of pier pins
vs imbedding section in concrete, I see, specifically, that pier pins are
not to be used with free standing towers (for obvious reasons) and not with
bracketed towers (for not quite so obvious reasons.) The point is that Rohn
makes a specific mention of that in their small blue brochure.
I also see the base plates and pier pins called out in the parts list in
their catalog for guyed 25, 45, and 55 towers but nothing is said, pro or
con, as far as I can see, about imbedding the base in concrete. We know
there are hundreds of acceptable configurations not specified in the Rohn
book. I would expect Rohn to say something about not using an embedded base
with a guyed tower if it were not recommended. Maybe they do say that and I
missed it.
Just trying to learn something new . . .
