RE: ribbon vs. tubing




In one of Richard Hull's video tapes there
was a primary made with ribbon.  The sharp
edges seemed to attract an inordinate
amount of strikes from the secondary.
When it was changed to copper tubing the
secondary streamers stopped striking it.
The self capacity would seem to be higher
also.  Richard's small coil uses ribbon
for the primary and seems to work very well
but it does not produce sparks big enough to
strike the primary.  I have always had good
results with copper tubing.  It is also good
for the electrostatic design of the TC.

|Greetings,
|
|I have started making my next coil.  It will be a 6" model, certainly
|bigger than my garage :-)
|
|I have been thinking about the primary and had a question.  I realized
|that the flashing that I use for capacitors comes in 4 or 6 inch widths.
|It is significantly cheaper than copper tubing, and I was wondering if I
|used ribbon of this flashing that had the same surface area as a tube of
|the proper diameter (say 1/2") if it would have the same current carrying
|capabilities and would work as well.
|
|I'm up for the experiment if no one knows, but I'd hate to just waste the
|money if someone has tried it before.
