Re: Large Flat Coil

hi
ok i ve just got my wire , its not brill but its wire ,im ready to
wind my flat coil ! i have a few questions concerning my construction
( or yours )
why is there so much space between your turns ? is your wire bare ?
my wire is plastic insulated stuff, equipment wire , its stranded
. i know it will work but, can i have like no space between my turns
, does there have to be space because of some odd thing to do with
flat coils , i dont want to spend days winding it by hand to
find that yet again ive done it wrong
my plan of action was ......
1, cut out a plexiglass disc ( size irrelevant )
2, in the centre of disc place another smaller disc this is to secure
the wire to in the centre and also act as a former for the first turns
3, mount it all on a moveable platter ( to aid winding )
4,spray contact adhesive to the upper side ( wire side of disc)
5,begin winding using each turn as a former for the next until
required size is achieved
ok this should give me a close wound perfectly flat coil i dont
really want it very wide probably about 24" in all including the
primary turn are there any more references to flat coils there
seems to be very little on flat "tesla coils" and the ones i can find
are too small or way too big
thanx earl
oh and whats so special about 455 khz

If its that close to 455 khz, it should kill radio reception for a
good distance. Not nice with close neighbors!
Fres measured 438.5 kHz. I tried to measure f2, but the generator
just won't output a high enough frequency (a thorn in my side a long
time now). Anyway, Javatc measured 455 kHz using measured radius
values from center of coil to the nearest wall. I ended up having to
