It is good you are still building and edging towards a working part G. i do like those slip rings. unfortunately i can not say the same as the things i am trying to hold on to is all packed up ready for storage. i will be working on getting restabilized to finish what i started. good to see you moving forward.
I wish to share my idea of build with you guys: how ever I would have slightly different approach . it is clear to me that somehow previous builders got slightly sidetrack from patent itself. What I find interesting that Figuera is using DC power to start running his device and then apparently recharges battery while generator is running. this I find myself very interesting , personally I have not an idea how figuera managed to convert pulsating output to DC that feeds primary coils via comutator. Considering that output of his device was some 550V I gess with no load . also his device was easy to start on press demonstrations and didn't need to run el motor. Perhaps it was running from some kind of battery... that brings me on subject battery cars been cranked up with handle and dynamos/magnetos supply spark and some cruel power. is it possible that we are simply overlooking the fact that Figuera run DC generator from secondary coils driven with AC motor.. this would perhaps support Marathonman with his idea of electric motor required. Obviously if this is the case ,MM would be correct of needing electric motor that would assist with production of DC for self running . First diode was to small to be used with Figuera and practical Selenium diode was in 1930 getting some attention
How ever this is my lack of understanding of this patent but there must be the way to replicate it

Welcome back Skyrob, i had moved your posts and i guess you thought i deleted it and you left so then i did delete it.
you are asking basic questions that have already been addressed. if you actually read what has been posted you would know exactly how the Figuera device operates. building a device without knowing how it operates is very foolish indeed. my suggestion to you is to read and study what i have posted in the tech thread especially on how part G uses DC and inductive reactance to control current flow.
"Marathonman with his idea of electric motor required" i have no clue where this came from as the patent states specifically there is a motor that rotates brushes and there is NO diodes in the Figuera device. again there needs to be more study of the patent and my posts before continuing forward.
This device output frequency depends on what Country you are from. the U.S. will be 3,600 rpm at 60 hz and most others will be 3,000 rpm at 50 hz. also please use the General discussion thread for chatter. of course a small AC motor can be used to rotate the brushes if you can find one small enough.
I have some kind of understanding how Figuera generator should operate and what outcome it should provide. Please I don't want to be disrespectful but give me a little space on my way of R/D . Im happy to share my wrong doing with this forum. I don't wish to argue about how it should be done , due my inability to inspect how real device operated. I have read your very large input of information about this device and that actually prompted me to share my thoughts with this group of enthusiasts , that use their free time to create what was buried long time ago.
Im happy if you let me inform forum in this place how I'm progressing.
Well I basically designed the following commutator first in a 3D software. this was the result. I only moved the middle bearing to the other side, and made the hollow shaft a bit longer. Next up was designing a shell. this i 3D pinted in 8 parts using standard PLA
Next up was printing the Coomutator bars. Used carbon here, and used 1mm thick copper tape for the inside lining. . cut 32 parts. Also had to cut the springs inside the brush holders in half, as they where pushing to hard. Brushes are wide enough to span 2 commutator contatcts. so there's a make before break going on

Yes he will have to machine them as the brush will jump like a school girl in a candy store. Peter; i was looking over your pics in my email, nice job on the 3D. hopefully you can match it up with a good core and get a good signal.
