Re: [ATM] wire size for dew circuit

[Charles Broward <cbroward@ufl.edu>]

Hi Bill,
Consider using the spider as 1/2 the circuit.  Your cat5 cable wire 
should work for the other half (or even both legs of the circuit), since 
it is less than 1/10 ohm per foot.  You could run your #18 from the 
controller to the spider assy, then use the short length of small wire.  
I made the center piece of my spider out of insulating material, and use 
two legs of the spider to carry the juice to the secondary....works good.

So, a quick "yay" to using your tiny wire the length of the spider arms, 
then use heavier wire from the top of the scope to the controller.
