[TowerTalk] More crank-up questions

[Roger (K8RI) on TT]

I'll try again...

Comparing the new base (yours) to the old base (mine), I'm wondering how 
different they are.

The old rebar cage is a simple affair consisting of a bunch of straight 
pieces tied together.  There are no bends.

The hole is 3'6" X 3'6" X 6'6" deep which appears minimal to me.

There are no bolts holding the base ears.  They are welded to #10 (inch 
and a quarter) 60" long rerod that extends to the top of the ears.  #3 
rerod extends them to within 6" of the bottom of the hole.  It does not 
give the latitude you have with two bolts holding each ear.  It's a 
strong set up, but appears much more primitive than your LM470 base
