Re: Spiral coils?

>Hello Tesla Coilers
>Do spiral secondaries work?

They do, but from things Ive heard, they dont seem like a great secondary
resonator. Their geometry alone makes them a pain. 
For an inductivley coupled secondary supplying a tertiary coil in a magnifier
system, this type of coil is more usefull.
A spiral magnifier tertiary can be centre fed, with the loading capacity on the 
outer turn....but alas I drift a bit off the subject here. 

>What is better more turns with fine wire or less turns with larger wire?

More turns with finer wire gives highr inductance, and bigger wire handles more
power but has less inductance. If you use big wire you'll end up with a big 
coil as per required inductance by the secondary circuit.
