Subject: Cap problems
Hi,
Help please :
I have hit the wall with capacitors. I have received several designs for
rolled caps from individuals and gleaned all that I can from the 'net.
However I am stuffed since I cannot find Al flashing here in NZ at all. They
just don't use it (as far as I can tell - and I have looked hard - believe me.)
I have blown several sets of glassware using Leyden Jars (which worked well
while they lasted, although the spark was very washy and green) and even
tried beer bottles. But they didn't last any time at all.
I am running a 15000V 60ma Neon with a twelve pole speed controlled rotary
+ adjustable static gaps. I have a lego system now. My frustration with
the caps has been vented on the coils (I just love to wind <g>) I have a
combination of 6 / 10 / 16 turn 3/8 inch copper primaries and an assortment
of secondaries all built on idendical formers so they can do a * mix and
match *. Results with the *Jars* to date have been noisy and impressive,
but the glass bill is sending me spare - not to mention the wasted time and
all that salt water and oil everywhere <g>.
I have even tried to get a commercial unit from the Roederstien rep here (I
can hear you gasp). They won't supply one off. I have a trip to Honolulu
on the 12/13 Mar - does anyone know if I can get Aluminium flashing there -
or better can I also buy a decent commercial 0.0127uf cap there? Failing
that - does anyone want to sell a 0.0127 or thereabouts cap.
If anyone wants to do a trade / deal / w.h.y. get back to me on email. I
can take delivery in HNL (which will save DHL costs) and pay in any currency
you want including an arm and a (opposite) leg <g>
I realise that most of the good coils out there are using homebrew poly
caps, but without the materials I cannot get away here. I will, I am sure
get some flashing in HNL (I hope), but I would also like to get some
flashover while I am waiting for the weeks to pass while the bubbles settle <g>.
I have wire, copper pipe, formers, rotaries, spark gap designs coming out of
my ears (almost) and a half decent toroid molding (made of newspaper and
water glue <papier macheé> ) just waiting for a foil outline. But I aint got
a capacitor worth a damn. Any ideas would be most welcome....
