Hi all, I am on the list serve now.
Bert Pool and I ran our maggie in Bert's back yard the other night.
It was our teslathon, I think. about 40 people showed up including
the treasure god Norm Whooton and the moderator for the Tesla list
serve, Storey Clamp. When tuning it the driver was very unhappy. I
went to my house and got a 30 in. smooth spun toroid to be a corona
ring for the driver. When I got back there was good food all ready to
eat. Good food Bert! Tuning the maggie proved to be a frustrating job
in all that wind. The wind blows out the arcs and it will result in
an arc from the secondary to the primary. Finally with the two tops
three feet in dia. stacked and separated for maximum terminal
capacitance it was running about 10 kw. and getting regular 11 to 12
ft. strikes to the tin roof Bert had grounded just for the occasion
had my cam corder on the only side of the yard that it did not mess
up. That is the side away from the driver. Getting close to the
driver really messes up my Sony camcorder. It won't reverse or
sometimes just beeps when turned on. After about 2 days, it will just
start working again....any comments?
After getting back the still pictures we noticed lots of strikes to
a citronella candle and just past it on the concrete! That is
conservatively 15 ft.!! We were set up exactly 9.2 ft. from the 4th
pole on the porch and it was 11 ft. to the third pole. The candle was
directly inbetween the 2nd and 3rd pole on the ground. That is
directly measurable to 15 ft.
15 ft. strikes, .015 total system capacitance, 10 kw., and 7.5 times
the resonator length. (Praises to Richard hull with 10 times the
Any comments on arcs 15 feet or more with .015 capacitance?
Since Bert Pool and I are now the TCBFW we have made a skydive banner
I have managed to jump and get video and stills of. The banner
flapped so violently that the video is worthless to get a picture
from but one of the pictures came out readable. I will post the
picture with the list serve.......It read,
Ed Wingate is the one who was selling the high voltage discharge caps
at Richard Hull's Teslathon last year. We got quite a few of them and
are currently punishing them on our maggie. Yea Ed!!!
We are now building a bigger conventional coil from an 18.5 in. tube.
I just bought 59 lbs of 14 ga. wire to wind on the secondary. Should
get a 20 foot spark! I hope. I did pay $200 for the new wire.
Since we got the current under control to 10kw this 2kw potential
transformer has not gotten hot! Only %500 overdrawn from the wall
plug is ok. Even for multiple 5 min. runs. We use to run it at 20 kw
and more just to see what would happen and it got hot. Sparks were
hotter too! But not significantly longer. Once resonance is achieved
at 10 kw the coil is about maxed out for spark length. We have never
destroyed a potential transformer yet.
Safe coiling to all!
