Re: Joining two rolls of wire on the secondary coil

Hi Jack

I have often had to remove shorted turns on my overcoupled 4 inch coil.
I suggest solder side to side to avoid it 'sticking out'. Leave a slight gap
on either side all the way around so your windings don't become eccentric.
The aim is to not have the bare solder touching the adjacent wire as there
is about a 500V difference in voltage between them. Then normal polyurethane
spray in layers. I've not had a problem with joins doing this. It ain't that
pretty though. Use a black marker around the gap to disguise it a bit.

I might also add that 4 x 48 inches is a 12 to 1 ratio where 4 -5 to 1 is
preferred. Maybe you should stop where you are if it is around 16 - 20
inches?
