Brandon,

I wound my first coil with #8 AWG PVC covered wire close wound on the
large
30 inch diameter secondary and it worked fine.  I wound my second 
coil with #12 AWG THHN plastic covered wire also close wound on a 30 
inch secondary.  It also works fine.  I'm toying with the idea of 
winding a *large* secondary with 410 Cable (0.410" diameter aluminum 
cable TV distribution hardline). Winding a grain silo sized secondary 
with aluminum will be a lot cheaper than winding one using copper.
