Hi All: Im looking forward for doing first test runs of this device , there is lot to be learn and figuera out :-) i'm going to take gamble on size of core "Y" and cut it on 30mm length primary are 70 mm this is just to check any performance and try to play with number of turns versus generated field Coils are 3D printed I have ordered Gaussmeter to get me some more reliable answers rather then paper clip tests when observing switching on "G" what waveform I should expect? Also What waveforms you have achieved on Secondary winding? I will measure secondary with and without load. www.magnetic-instrument.com/teslameter-13.htm

If you had done your research properly and read the TECH INFO THREAD you would know Part G will have an always positive wave form similar to an AC wave form with each end 180 degrees out from each other, one rising the other falling and vise verse. that means two wave forms, one for set N the other for set S. an oscilloscope is good to observe the wave forms of part G. this isn't like sitting in back of the class and copying off the person in front of you, you people should know these things in your research of this device. i teach not babysit. the secondary should output regular AC with the frequency according to the RPM of part G. the secondary will not have an output without a load therefore it can not be tested without a load because the secondary must form an opposing field when current flows and it is this field that is pushed side to side in the sweeping action. so no load, no secondary opposing field, no output. a Gauss meter is good but it will not give actual lbs pull force. you will have to rig up a test similar to what i described in the tech thread. Secondary to primary ratio sounds good as anything at 2 to 1 ratio and over will be just great so you are good there. bobbins look really nice, good job on that. cores are another issue, it makes no sense having the cores attached to each other like that as the ends will be opposing anyways so no benefit there just a waste of money. you can NOT have the cores N><N and S><S next to each other as they will siphon off flux from each other as the magnetic field will find the shortest path which will substantially reduce your output. Figuera built his device this way for a reason so they have to be N><N, all of them. other then those glaring mistakes and research you are doing just fine. Regards, Marathonman

Hi MM : everything you have mentioned is taken on the board, thank you for your kind words. The cores are as I have salvaged from my old transformers and first set is N-N and second set is S-S , secondary winding doesn't care North or South is fluxing other storie will be if phase would match but that is easy to see I was hoping that you would have actually real test oscilloscope image , but not to worry i will post it for sure. In respect of G im counting on serious fallbacks but to get the knowledge of circuit I will try resistive approach and then inductive approach and compare waveforms. Im sorry but this is R/D research and I really willing to learn on my mistakes. I would love to have crystal ball and check our friend in 1902-1908. thank you for giving hints and checking up on me, after all if not this board I would never try it I have also traditional cores stand by , no problems to swap them and test them out (like yours )

Quote; "secondary winding doesn't care North or South is fluxing"
I am well aware of that, what i am referring to is the North fields being siphoned off to the south core before it has a chance to go through the secondary. it will interrupt the sweeping action taking a shortcut through the core next to it. this is one of the reasons why Figuera used all north cores. simple logic

did you try it? wires on coils can be reversed and then will be poles opposing all N or All S again this is R/D core can be cut or thrown away , no problems Im getting ahead of myself with the cores , comutator needs a lots of work and it is not functioning yet

Irregardless of whether the original replicator or myself said, this will be the outcome as it is basic common sense action of a magnetic field. it will take the shortest path always if presented and especially since the four fields are compressed causing them to be even closer from the bulging effect. it helps to try to visualize the fields as they sweep from side to side under compression. your cores are just fine, just think what would a magnetic field do knowing electric and magnetic field is very lazy and takes the easy way out always. these post need to be in the Figuera general discussion so let try to minimize the build thread chatter, myself included.

Comutator "G" part Machined, glued and ready for wiring attachment to "R" it is still missing the brush........

Nice machining Skyrob even though "R" doesn't exist we can go along with it. it sure pays to have the proper tools. again need i remind people that according to the patent "R" is drawn in it's elementary manor to facilitate the comprehension of the device only. this means "R" in reality does not exist in the form shown in the patent drawing. "R" and "G" are one and the same as a rotating inductor that uses inductive reactance to control current flow with no standard model of resistance what so ever.
people should be aware of their interpretation of the patent which could lead yourself in the wrong direction quite easily.

Nice work Skyrob, just remember that the brush must be more than one segment wide to make before it breaks contact, otherwise you will be switching the primaries on and off which will unleash sparking from inductive kickback, and fry everything .
All the Best, Cornboy.

and now this important part, not knowing how much inductance would be required on each step 1 to 8 then I have divided variac on 7 equal sections . Preliminary test demonstrated nice voltage dividing from 30V whole variac (20 ohms) and my coils 18 ohms , to my surprise voltage did split 30V before Variac and 13V after Variac then with this coil I will get some saturation , cant wait for gaussmeter to test saturation of cores. the idea is to start increase current till complete saturation of core is achieved , after full saturation of core any additional increase of field is just spoiled on heat in core and in coil, there is fine line to get the maximum magnetic force. all this is just a preparation to prove concept only

Just how are you doing your voltage testing because i can tell you right now you have to many winds on your core just like Creasysee's electronic version did or does. to many winds when switched will cause to much inductance and in turn to much of a current drop. you have over a 2 to 1 ratio so that means you have to reduce your total at or less then 1/3 to get the sweeping action you need with proper compression.
having so many winds of induction at switching is going to have adverse effects compared to direct winding contact like in the patent. another thing is 20 ohms is a lot of resistance considering part G should be darn near zero and that goes for your primaries also. the more the resistance the more losses occurred especially considering part G controls the current flow NOT the primaries.
I guess sound reasoning, bench test and sound Physics isn't enough for you to follow on your own isn't it. Quote; " all this is just a preparation to prove concept only" if the concept doesn't work then what is the point of attempt. this is like watching the Democrats trying to impeach Trump...crash and burn.
i would offer a good luck gesture but in this case even a truck load wouldn't help you as you just do not listen like those on OU and EF. resistance does not control current flow, inductive reactance does. i am not being mean i am being realistic.

Hi MM
Thank you for watching my progress I’m not scientist, just technician I will continue with my set plan and do testing It may seams to be wrong way but I need to feel it. I’m taking your comments on board and if it will require I will build different “R” To be more suitable I can feel from your comments that you care and wish for successful replication of CF device
I have committed myself to be successful
We can save ourself lots of typing if we Skype each other There is other applications on the phone like WhatsApp And it is much better for quick communication We can set up group with builders only , just a wild thought

Skyrob, this thread is for builders only no need for Skype and we also have a general Figuera discussion thread for this very thing.. if you need quick communication you can either Pm me or i can enable the shoutbox again which is like Pming only visible. yes, you are correct i do care because over the last 6 years i have seen a boat load of people stray from the patent and wind up with a non working device then rant this device doesn't work. WRONG ! Figuera took two devices to the patent office in WORKING CONDITION. this is something the ney-sayer and mouthers conveniently seem to forget in their quest to belittle or discredit me which rolls right off my back like water on a duck.
the biggest challenge is the first step to decide to come forward and attempt a build which you have already taken. bravo.
PS. nice guassmeter.
Regards, Marathonman
