Hi Terry,

I might have said this before, but I have had the same happen. My 15" coil in the driveway could do around 2-2 1/2', but when I used it on stage, it had an extra 4' of hight above the concrete with streamers hitting the 4+ foot mark. The same may have happened to Bob's toy. Also coil tunning can vary from day to day. My older 6" liked to vary over about 3/8 of a turn for best spark length.

Hi Mike,

I have a small coil I recently took to a science center. I stupidly had it on the school gym's tile over concrete ground and noted to "all" that it was not running well!!! Folks here on the list that saw the pics reminded me that the concrete floor it was on was very close and was probably killing its power... I latter re-tested all of the coil's parts and they were fine.... Running thousands of high currents volts next to odd "ground" surfaces is a "bad thing". Perhaps Leadville's ground is not called "lead" for nothing ;-))

20 years latter....  We can "detect and find" such things...

Note to all to be careful of objects next to your primaries!!!!!!!!!!!!

Cheers,

        Terry

Hi All,
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.
Mike
