Re: Re: [TCML] method of routing secondary wire to toroid



This leads me to amplify a bit about mine: I mount the toroid using 3 hollow standoffs fastened to the web of the 6"x24" Landergren toroid, which slip down over 3 pins mounted to the top plate of the secondary. The juice flows thru one of those connections.

As to the other end, I took an electrical "plug button", some 1 1/4" in diameter (the object that is used to plug a hole in an electrical box), mounted it on the bottom plate at the center, and soldered the low end of the secondary to it. Then just a small spring standing up in the center of where the coil mounts conducts the juice to ground. That way I can just plop the coil down in place without worrying about orientation or plugging anything in.

I searched the archives, but can't find the specific answer I'm looking for. What is the best way to route the secondary wire from the last turn to the toroid? I've read where some space wind in free air up to the base of the
toroid,
I made my secondaries with the wire ending at both sides soldered at rounded rectangles of brass foil
glued to the tube.
The assemblies at the lower and upper ends touch these tabs with metal foil springs. Nothing critical,
as the current there is not too high, and very solid and robust.
