FWIW
The foundation iron (Rebar/flat plate for bolting tower legs to) for the
LM470 tower was furnished by the mfr. as a welded assembly.  There
was/is(?) no need to jiggle the each rebar--necessary to keep the entire
assembly vertically plumbed.  This assembly was perhaps 3 1/2
feet long and it was left to the user to "wire" up an extension rebar at
the bottom of the welded assembly.
