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.

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
