I only used 3500# concrete which was more than called for. Had we moved
the tower base to where I would have preferred it, it would have pretty
much doubled the concrete from 5 to 10 Cu Yards. Unfortunately the yard
was just too soft and even the wheelbarrows were beginning to cause
ruts. It'd been another $500 to a $1000 to get it pumped, but at only
$120/yard It might have been the time, Then again, with that area being
in the change from clay to peat, I don't think they'd have been able to
dig the hole by hand. It would have required the steel, industrial
forms and the equipment to handle them.
I gotta hurry and do something about that winch. Without modification,
it'll never hold up. I need to drill out the supports for the bushings
and add zerks to keep them greased.. I may need to replace the bushings
with sintered bronze, grooved to distribute the grease. What ever, the
industrial supplier will provide what I need.
The problem is, it takes me so much longer to do things, and I still
estimate times as I did when everything worked.
Oh! I ordered the standard tilt plate, but one that doesn't go on top.
I Think I'll run the mast up another 3 feet and mount the 144/440
duoband vertical on top.

I ordered 5000# concrete and according to my PE, was able to put my TX472 up in
three days. As it turned out, because of other issues, I didn't get all my
ducks in a row 'til about a week after the pour. 3 years later, it's still up
with no adverse signs.
The only troubles I had were related to antennas & HDR300 rotator.

Thanks guys. I am planning on waiting a few more weeks before raising the
tower. We have been pretty lucky with some pretty consistent rain, which will
only help hydration.
I ran into some rotor trouble today with the T2X, so that will give me some fun
to pass the time away...
73's and see yall in the pile ups...
