Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

@ All:

OK.  I have now wrapped my second coil with 1 layer.  Everything 100% cotton insulated this time. (no salt)  I have 2 questions.  I started at the top of my spike (the head of the "nail") and wound down.  How the heck do you reverse and go back up and still keep from shorting?  Do you get to the bottom, then re-insulated the first layer, and then wind back up?

Next, when I wind the secondary.  What do you do with the 2 wire ends of that?  Do they become the leads for the load?  Does it derive its power through induction and does not have to be connected (wired) to the primary?  Stupid, basic questions I know, but, I am at a loss here to find anything in any of my books to tell me this.  Any advice would be greatly appreciated.

I believe I have enough materials for a complete second layer over my 12" long spike.  This should give me better results than my first attempt at only one layer.  No shorts as of yet.  I hope everyone else is doing well with their cells.

Bill,
I am winding third layer as of now.  All the leads will be at the top of the coil so I can experiment in the future by connecting them in various configuration.  My coil is bare copper and iron wires with two cotton strings.  Between each layer I have wrapped around piece of old t-shirt.  My next coil will have braided insulation on copper wire.  I have ordered 100' of braided tube.  The problem is what diameter of wire to use.   Is there any way to contact that person in the NS museum and ask about approximate wire sizes on the coils?

Great looking setup Georgemay

@ sid10:

Thank you for your response and the information.  I kind of thought that was how it was but now I know.  Thanks.


@ George:

Wow!  That is one heck of a setup you have there.  You can have actually have fun winding the secondary on your lathe.  I read that Tesla used a lathe also for his windings.  Three layers should work well for you.  I think I only have enough wire to do two.  I am also using cotton string in between as you are.  It compresses  very tight and it allows for a closer clearance between the wires than I could ever obtain with any cotton material I have.  That is a nice looking lathe you have there.  I sure miss mine.

@ Bill,

If you have still problems getting the residual moisture out of your coil, soak it in methylated spirit. This will combine with any water that is left and it will dry out very well.

@ Hans:

Thank you for your suggestion.  I will give that a try.
