Re: strength of vacuum



Original poster: "Laurence Davis" <meknar-at-hotmail-dot-com> 

I believe the original poster was interested in "strength of vacuum" for 
insulation purposes
for very high coupling around 0.35.

your current secondary is in oil running at a coupling of .35 or so.
im guessing you're trying to prevent racing.

have you tried spacewinding using fishing line as a spacer?
as in two spools next to each other that you wind simultaneusly on the 
secondary form?
then poly as usual.

the only problem i see with that is the temperature expansion coeff of 
copper vs fishing line.
and tensioning may be a problem.

wouldn't self capacitance drop when space winding a secondary?

larry.
