Ignitrons must be oriented vertically (or mostly vertically). Sloshing
the mercury around shouldn't hurt it any.

All,

I went both Friday and Saturday. Used SB50 and a hat and had absolutely
no sunburn whatsoever - a real first for me since I usually end up
looking like a lobster after only a couple of hours. My best finds
included what appears to be a new 833A with clamps for the base
(filament) connections for $5.00, a HV filament transformer to drive it
for $2.00 (with 2" high insulators), a batch of metal-cased high voltage
caps which appear to be mylar or oil-paper, ranging from 5,000 volts to
30,000 volts for $2 each, a pair of heavy duty 0.005 and 0.002 uF 5KV
mica caps (for a toob coil at $25/pair). 

Also got some very nice 4" high ceramic "beehive" feed-thru insulators
($3.50 each), and a new 3A variac for $5.00. Overall, there was really
not a whole lot of high voltage/Tesla type equipment at the Hamvention
compared to the size of the event. I DID manage to get the names of a
contact who had more HV equipment at home that I'll need to follow-up
with. 

Had very good visits with about fellow coilers on both days, swapping
"war stories" and viewing each others' pictures. Glenn Cerny, Robert
Stephens and I also had a great visit with Scotty Myers at Piqua. It WAS
sort of like a mini-Teslathon. Hope to see some of you again next year!
