"To collapse or not collapse... That is the question"

And I have and answer!! , well guys it happens that while ago I made a bedini bifilar coil for my gigantic 5 ft diameter rotor, but never had time to make the other 20 coils ...But hey! with ony that one coil I got results , slow but nonetheless a tiny bit overunity...thing is:
The core was made with a special welding wire which doesn't retains magnetism! 
Now excuse my bad memory but right now I don't have the number or specs for it , but by going to the builders site for the bedini wheel you will find it for sure.
The possibilities are endless I might say because you can fabricate as thick or long as you might require for your core.
I used my dremel drill to cut the metal down to the required length, like I said I'm out of usa and will inquire at home for it, but everything is in storage right now.
And thank you folks for answering my questions and clarifying some more. I'm building big as soon as i can and will show results for all to see.
In the meantime i want to tell you I had this thick coper and iron coil as tall as a foot and half of that in diameter ,all found in a garage sale , so I submerged in water in a huge glass jar..I got about 1.5 volts but not signigicative current just milliamps, that upset me a bit then the next day i got less and so forth...then one day,
I saw my wife's cat drinking the water from the jar !! ...The thing was working perfectly , but didn't notice a difference wet or dry and i was using bare iron and copper wire no layers in between , I think that's why the amps were so low, then again the pulser with a transistor was the next step...Then i had to work in a foreing primitive country... I knew it would work , now guys the possibilities are endless, but the fight is just starting, talking about the acceptance of this technology by the stablishment, but I'm a fighter and I will like you pushing through I have very strong reasons to do so...
Thank you again , and keep up with the good work!

Hi kukul...d,
That is a very cool experience.
Do you think there was ever any cotton insulation on the copper?
Was it varnished copper like jim's?

What I have been not asking very well is 'how well can a thing like this work if I have only a 3/32 inch diameter welding rod as a core?'
It is very skinny.
I think I will give it a small trial today. I do not want to waste my special copper wire on a little thing that cannot work because of its small diameter, but maybe I can steal just a little from my supply?

So, do YOU (or anyone else) think this will work on a skinny rod?

thank you,

jeanna

@Jeanna
I'd say that yes, it will work. As well as and as efficiently as LaserSaber's? Probably not.

I'm very interested to know, though.

Here is my winding jig. Simple but very effective.

I think I have some good news here.  About a month ago I contacted some friends in Canada and told them about the Stubblefield coil and asked if they had ever seen or heard of such a thing.  Yesterday I received a letter that there is a man up there who owns one, or what they believe to be one.  It is described as being 11 1/2 inches long and 7 inches across.  It has a cotton covering on the wires, and he says it is very old.  I plan to take a trip up there and see just what he has and offer to buy it.  I am not sure if the guy knows what he has, or not.  He also has a lot of other items that they say appear to be electrical, so hopefully I will find a treasure trove there.  It sounds very promising...so wish me luck!
