That is a good point about the coil to ground, I asked about
inductance per winding, etc, Bob said he had that all down, would look for
it for me. Also, he did measure Q I found out tonight, he had at some point
decent meters, other coilers that visited had some as well.
He had built it to as close as the CS coil because he wanted to duplicate
conditions to see if BL was what Tesla had seen. But you are right Terry,
the earth conditions at CS sure could have been different.
When Bob ran this out in the open on the salt flats, he said it never ran
as well as it later did in the hanger.
By the way, in pictures yet to be scanned, one can see the curve of the
hanger roof better and the coil size ratio.
The very top of the hanger, which Bob measured with a plumb line, to the
floor, was 95 feet.
So that is the highest point above ground, that being the top tin skin of
the hangar. The Z braced supports which follow the roof curve were about 6
feet; They used to have to climb up those and pull an overhead light to
them, for bulb changing.
I also see I must re-scan the posted pictures, I think the transformer in a
desk light may have bothered the scanner as there are distortions not on
the original pictures.

In the new photos Mike posted, the picture labeled "Inside Building View
Coil At Climax Mine Leadville Co.jpg" appears to show the coil built on
top of a raised floor, maybe as much as 2 feet off the ground. Someone
had mentioned that the coil may have suffered from some parasitic losses
due to being on the ground.
2 feet my seem like a lot to "us", but for a 51 foot diameter primary that
is real close. If you scale 51 feet to two feet, then 2 feet becomes 1/2
inch off the ground!! I think Tesla's original coil was on a sandstone
ledge that might have been a darn good insulating platform. Very possible
wet ground in LeadVille sucking up the primary power was the cause of the
poor performance reported.
BTW - I see Bob even made the tower!!!
