Don't start pulling your BS on me seaad, as you never asked me if the winding is continuous or i just plain missed it, please next time you ask a question try being a little more descriptive in your question if you are able to do so. otherwise i will turn my back on you and your belittle BS games. start acting like a researcher and you will get a little more respect from people.
as for the next question which is the same yes part G one of them is a continuous wind which is the one mr. Doug built. my new core is not.
yes i am using the same core just rewound with 80 winds CW.
and as for your last question i have not completed the last rewind of one primary as i switches to three winds of two layers each after testing and have not completed. this will give me all connection at the end of the primaries for ease of connection and a stronger magnetic field.
so no my unit is not ou as yet as i am not quite finished.
not everyone on this world has money to burn and must fit within a budget which i am no exception. if i has a few thousand dollars i of course would be finished.
research to prove is cheap but actual build cost very much when living in a city where no scrap parts are around.

The whole reason i rewound my primaries was two reasons, 1.  the fact that they were shy in the lbs pressure produced even with the Tesla style of winding 2. there was an accident moving the equipment to a larger facility other than my tiny place i have to work. the box with the cores was dropped smashing one core all to hell and mangling my brush holder. on a limited budget this was devastating so it has taken a few months to get back up to par. my income tax return helped a little but i still had bills to pay. as we all know life will be life and can not be avoided.
i was getting fairly good results with part G but the balancing issue of the ring type core was plaguing me and i could not get the exact balance of the peak to peak of the primaries. the balancing is sill being worked on along with a new core design to eliminate this plaguing issue. with the new design i have the brush holder is adjustable to dial in the exact window of highs and lows of currant per the secondary to primary ratio. part G as an inductor works exactly as planned even though many are against it.
fortunately i have Physics on my side and part G works just fine so i need not listen to people that just don't know. that is just the follies in new territory of unproven tech that just so happens to be 110 years old. i stepped into this journey with a completely open mind and man have i learned a lot unlike a select few that choose to remain closed minded.
Figuera was a sheer genius and i wish people would open their minds to a new reality that just very well might change our way of life and at a bare minimum you just might learn something new.
PS. here is a pic of one of my primaries after the box drop. my suggestion to everyone is not let anyone touch your device period especially if they are a klutz. i had to completely rebuild them from the bobbins up. as painful as it was i had no choice but to keep chugging along.

Part G ring core does in fact work, i repeat, part G ring core does work but the balancing of the primaries are a complete pain in the back side consisting of shutting the system off and moving the adjustable connectors i posted a while back a little at a time tightening everything then turning the system back on and testing. it is a royal pain in the backside so i decided to take another approach along with the ring type core. i now will have two types of part G core for testing purposes.
before mouths and accusation start flying i just want to say that the ring type does work , i just wanted to try to see if i can build part G that is easier to wind and easier to balance for replication purposes.
on that note i ordered a special C core of my own design a month back and just received that has a large flat surface which to wind on. i will be using square magnet wire as to reduce the amount of copper losses associated with a high speed precision ground buffed surface for the brush to rotate on. the core is a closed core which is a must in the Figuera device as there are to much flux losses associated with an open core and thus will not work in the Figuera device.
the C will be much easier to wind and adjust according to my present understanding and experience of part G thus i foresee no additional problems associated with this design. after i have wound the C i can attach the other C to close the core then begin testing.
the only reason i am doing this is i am trying to come up with a way for easier replication of part G and no other reason but that. this will be tested right along with the ring core that has already proven it's self on the bench.

here is a pic of my new core, lets just hope it was money well spent. and of course a good shot of man hands that are good tools to work with. ha, ha, ha, ha!

One thing i do not like with the C Core is the edges have no chamfer like i said i wanted so either i have to grind them down or maybe use 1/2 round molding. either way i do need to get rid of those sharp edges as that will pierce the insulation on the wire. i only have to do it to the upper piece on both sides so that will not take that long.

also the Core is around 1500 va so if i add core sets to increase the output i can do so with no ill effects which will still leave head room in part G. if at any time the core saturates it will kill the device so keep that in mind, that goes for the secondary also.

all in all i am very happy how the core turned out but i will be much happier when it is on the bench. the shop almost used the wrong dimensions so just as a precaution i sent them a pic of their own core from their web site with the proper dim's and thank god i did as the dude had a few dim's switched around which i would of went ballistic upon site of. not good considering what i paid for it. when i opened the box i was grinning from ear to ear.

yes the square wire will be awesome for this project which will allow me to grind perfectly flat with very little copper losses. like i said i am using a slow curing epoxy on the core then after winding i will tip it over and put a heavy weight on it then cure over night. then hit with the high speed buffer to precision flatness. i really foresee no complication in these steps.

after that i can set the size of my reduction window in my adjustable brush holder to get the proper width of the primary sweeping action over the secondary. if the reduction is to much but with proper window size all i have to do is take off some winding's on the ends of the core and i will be perfect. this is much easier than what i had to go through with the ring type part G to get balance of the peak of both primaries.

the video i plan on making will be both cores with 100 watt bulbs connected to both sides one increasing and one decreasing in complete unison to completely stifle all those who disbelieve part G is not an inductor.

i sooooo look forward to that.

after almost 6 long years of research, testing and benching i am finally coming to the apex of my labor thus picking the Fruit from the seeds planted by Figuera with the help of Mr. Doug for which i am forever grateful.
some mistakes were made in the past but hey, that is just part of research and the learning process. without mistakes the truth will never be known and all one has to do is take that first step outside of ones box.

you mentioned you need bits and pieces or parts which might be recycled from discarded items?but your city did not have these available [some have rules about touching curbside items]?perhaps you could make a wish list of these parts ?there are plenty of fellows here who would send  items they have no need of ,or even persons reading here who would keep an eye open for such an item to donate?
just a thought
