K7LXC requested I post a summary of the rebar tips I received. Happy to
comply, and I shouldn't have needed prodding.
On Rohn's requirement that cages NOT be welded:
1. Welding weakens rebar.
2. Welding doesn't weaken rebar (IF the proper rod
On whether to tie rebar to tower or not:
No contest, everyone said tie it.
On Ufer grounds:
Tie rebar tightly to maximize lightning
current distribution thru concrete.
(Visit Polyphaser WWW site for lots more)
On general placement:
Support cage on bricks to keep rebar
On rebar numbering:
Rebar comes in one eighth sizes. #7 is 7/8 in,
#3 is 3/8 in., etc.
General note on Rohn spec: Rohn calls for number 7 rebar. I was unable
to obtain it, and after talking to a concrete guy, used number 5 at
decreased spacing. Even after buying a rebar bender ($25 at Home
Despot), I was barely able bend the number 5. It must take a real
gorilla to hand bend number 7.
