The page isn't finished as I don't have photos of the connections to
the tower legs, or any of actually using the hydraulic drilling, but
some may find it helpful. The connection images should be up in a
week or so, but I may have to wait till spring to get some photos of
the actual drilling process. Currently I'd have to thaw the ground
before drilling and it'd make one whale of a mess.
BTW, the hydraulic drill works in clay and or sand. Even in sand it
wets the sand enough that it doesn't normally fill in as soon as you
pull the drill. I emphasize "doesn't usually".
