El Nino has been slamming us a bit this past week, so the crane work
has been moved to Mon, 17 Nov.  

You might be surprised at how small the primary coilform is for this TC -- 

Form        - cylindrical
Winding dia - 31"
Winding len - 15"
# of turns  - 10, spaced on 1.5" turn-to-turn centers
Conductor   - 1.15" OD dia copper pipe
Inductance  - 78.7 uH -at- T10
              66.7 uH -at- T09
              55.6 uH -at- T08
Coupling    - 0.15 to 0.28, adjustable

Keep in mind that this coil is built 'inside-out', where the secondary
is wound on the _inside_ of a fiberglass cylinder, and the primary is
positioned inside the secondary, thus requiring a compact primary form.
Pix are forthcoming.
