Some of Armagdns advice finally sunk into my pea sized brain and I wound a small toroidal transformer from scratch, placing 10 turns around the circumference before winding the secondary in the usual fashion. I commend you on your own build, I'm looking forward to what you come up with. I know it ain't easy getting stuff done on a shoestring budget. I've taken to roaming the streets collecting all the electrical junk people throw out for council pickup and taking it home to salvage parts for use and for scrap. @ 80 cents a kilo for transformers and motors it takes a fair weight before you get any significant funds from the recyclers but it's better than nothing.
In my travels I recently came across some audio equipment which netted a transformer I haven't come across before. I believe it may be similar to what Eric described in his post. It is a round core shaped in a rectangle with rounded edges. What I found interesting was the method of construction of the core itself. It seems to be made of fine (steel?) laminations, the first layer very thin in width and each layer progressively thicker till it reaches the center of the core then the reverse, giving the rounded effect to the core. Was a real dog to get out, covered in resin and plastic. I'm still trying to get the windings off to see if it is split in half or if it is one solid piece. It's probably old hat to the veterans here, but it was new to me and seemed to fit the description Eric wrote about. I will post a picture if anyone is interested.
I really hope this thread doesn't turn into a ****fight, it is one of the few places left on the Internet I look forward to visiting, and revisiting. I'd like to make a small donation to Eric when I get home. It won't be much but every dollar counts. I really do appreciate all he has shared here. It takes guts to do what he has done despite all the **** that has come his way because of it.
Im happy to see people alot more knowledgeable are digesting this information and are attempting to put it into practice. I don't expect anything amazing from my own efforts, lacking the complete understanding of what is really going on here, but it's fun to try. Every now and then something sinks in and progress is made.
Regards

It doesn't need to be that complex to get the effect. Are you only planning on ever building one full scale model, and what are you going to do with it?? All I'm saying is that not fully understanding the maths shouldn't prevent one from experimenting with such things because the experimenting would not be wasted time.
Eric's video from 1988 or whatever clearly shows how to build a basic working model to begin experimenting with. A lot is revealed just by doing that. Then just recently, in fact in the TMT thread that Eric doesn't like and elsewhere on this forum, information has been shared regarding the construction based on Eric's information and Tesla's own words, so frankly there is enough information already available to at least build a small scale model that is almost guaranteed to work to a certain degree. A 51 metre diameter TMT or full scale Wardenclyffe tower would not happen immediately I agree. But the point is that Tesla had less information when he started than we have here, and he could figure things out and tweak things through the whole process of developing it, starting small and having things reveal themselves I would imagine. So just by using the available information anyone can get started, and one can't really NOT learn something from it, and develop one's own understanding "naturally". And there's so little wire in reconstructing something like Eric's small flat spiral coils it's not even expensive to find out these things and get started. Much cheaper than a lot of the other projects that are going on here. I don't see why it's necessary to fully understand all the maths just to be able to build something that works.
