[Lowfer] Interesting finding

[Ed Phillips]

"Sorry to say, Ed, looks like we are in a race, likely only limited by
the area of our sheds, basements, garages, car trunks, attics, mom's ...
well, you get it."

	I'll bet I won that race years ago!  I've had almost 70 years to get
ahead, but I'm not the champ either.  Used to have a friend in Pasadena
(W6CLW) who built three quonset huts in his back yard to hold his junk. 
However, he wasn't the champ either.  I once bought some antique radio
books and stuff from the wife of the deceased champ.  She wrote me that
he'd filled the house, the attic, three quonset huts, a couple of
storage sheds, and their guest house!

"Yeah, those guys have build rolled composite affairs, as Mike alluded,
and oiled them. I think Ralph's site had info on that technique. If not
him, another site under "Tesla" and "capacitor" should find it."

	The rolled capacitors are a perfectly good way to go for Tesla stuff,
as they're pretty low loss and easy to rebuild; the usual construction
approaches that of the extended foil capacitor and the guys who came up
with them knew what they were doing.  Also big, messy, and no where near
stable enough for tuning narrow band transmitters.  More lately someone
has come on the idea of using large banks of pulse-rated tubular
capacitors in series/parallel.  That's a lot easier to build and works
exceedingly well.  In fact, it's sort of revolutionized the world of TC
building, said world being at least as weird as that of lowfers!  Some
of those guys are running over 25 kW and producing arcs well over 20
feet long! Not the sort of thing that would go unnoticed in the
household or neighborhood..........

"Shhh, I'm looking for two projects that with help from wifey have
escaped my notice. One was an almost completed probe amp, yeah, the one
I wanna get up on the tower. Be damned if I start another one before
first emptying my half of the basement."

	I have problems with wifely "neating up" around here too!
