[UK-CONTEST] Tower Question

[C Swallow]

Arian,

The recommended method of doing this is to use a cone. These are available
commercially although I am blowed if I can remember the correct name for
them. I purchased mine locally when I installed my T120 a few years ago.
These are removed when the concrete has set. Once the base is installed (do
not forget to shim is off the concrete by a few mills) the gap including the
holes left by the cones if filled with yet another commercial product whose
name escapes me.

Hope this helps although it probably only caused more confusion.

Subject: [UK-CONTEST] Tower Question

The great day has finally arrived, and Tower number one is being installed
on Saturday.....well, the Concrete is being poured !
 
A quick question: The Tower is an old BXI Tower, that was originally post
mounted.( I cut the post at ground level to remove it, (its the one from
your neck of the woods, Dave) and have since had a 1 Metre Square sheet
Steel plate (28mm thick) welded to the post, complete with fillets. So it
now looks like a Base type of mount. (Typical Versatower)).
 
Anyway, as I havn't any documentation for the tower, so.... I am going to
pour C35 Grade concrete into a 1m X 1m X 1m hole. The retaining studs that
run through the base plate and into concrete, are made of 35mm studding,
85cm long (75cm in concrete). Each length of studding has a 15cm Square
plate (28mm thick) welded to its base. The idea being that the Square plate
will anchor the stud (and the base plate) to the concrete.
 
Each of the Four Studs will be held in place by a wooden frame, the concrete
being poured in, and around the studs, and the frame removed after the
concrete has gone off. 
 
Two Questions: 
 
Given the mast will be guyed with Steel Rope, does the above seem OK ?
 
I want the studs to have some "play" (not much say 10 mm or so, just to
allow instalation) so I plan on wrapping them in some foam piping   (sort of
thing to insulate lofts) for the top 30cm or so. Does this sound reasonable
?
