I think that was called the "wonder post" Aluma uses it now it 6" diameter and
14 ft long, 6 ft in
the ground wit out ant concrete. I have one with a 75 ft hd crank up and its
great, its been up 5
years now, of course the clay here is like concrete. The tower only weighs 290
lbs.

My first tower was a 50 foot crank-up crank-over by E-Z-Way.?? It mounted on a
steel pole...?
roughly?10-12 inches in diameter.? 9 feet or so above ground level that
connected to the tower?via a
hinge.? It went?a it over 4 feet into the ground.? There were 4 plates welded
at right angles at
the?bottom and a?foot below ground level.? It worked fine with a Classic 33
tri-bander.? I'd think
that pipe of yours is plenty, even if not structural steel.

Subject: [TowerTalk] congrete filled steel for tower base
Hi all, I have a tr ex 51' crank up I am going to srrect. I live a long way
from any concrete supply
and am looking for a way around the big expense of delivery.
Earlier, I salvaged a large steel tube 24" across with 5/8" walls by 20' long.
from another project. It is already filled with concrete. My plan is to auger a
24" hole in the
ground as deep as possible (6 to 8') , cut the tube, insert it and use it for
my base. I would weld
brackets directly to the 5/8 plate on the top to bolt the legs to. I could mix
enough concrete for
a shallow pad around it. What do you think of this idea? the tower would be
directly grounded
through the tube right into the water table. Is there a concern for lightning
strikes in the base or
any other potential problems anyone can see? It would certainly be grounded
well ! ...any guidance
appreciated.
TNX in advance
Ken
