Slightly delayed update.

	I've wound one leg with 12 turns of #6 A.W.G wire and get 7.5
Vac open circuit and 65 amps short circuit. When I connected this
secondary up to a pair of "resistance heating tongs" I was able to
bring a 3" section of 1" copper water pipe to soldering temperature in
about 10 seconds. I don't have enough voltage/current to spot weld
like I first thought though. I do plan to wind the other leg to get
15.8v - 2*0.7v = 14.4v at 65 amps for battery charging or put them in
parallel for twice the  current. I'm just not up to counting to 23K by
1s to wind a new secondary.
