>> Hey fellows,
>>
>> Don't be afraid to pull out your coil and fire it in extreme cold.
>> Actually, to my understanding, Tesla coils actually prefer the drier
>> colder conditions as opposed to the warmer, more humid conditions
>> for making sparks anyway. Obviously, you would
>> NOT want to fire one off outdoors unprotected
>> during a rainstorm but the ambient temperature isn't that big of an
>> issue IMHO. And Christopher Hooper
>> has made it clear that coils don't MIND firing
>> in the extreme heat environment of a southern
>> Arizona summer, either. I think the main concern
>> with the extreme temperatures is the coefficient
>> expansion/contraction caused by large swings
>> in ambient temperatures, possibly causing the windings
>> of the secondary to slip off and fall down during
>> very low temperatures. It has been my experience
>> that mulitple layers of Minwax Marine Spar Var-
>> nish will protect the secondary from this fate without
>> chipping or cracking itself. Glyptal is a bit more expensive
>> but will probably do it in one or two coats. I reside in the
>> Memphis, TN area where we virtually never get sub-zero
>> cold but never-the-less do get considerable sub-freezing
>> temps during the middle of winter and PLENTY of
>> the "3 H's" - hazy, hot, humid - during the summer
>> months (90's virually every day with mid-70's dew
>> points -- in other words, miserable heat & humidity)
>> and I've never had any problems with my coils due to
>> the seasonal temperature changes here from storing
>> them in the un-climate controlled environment of my
