I agree with your conclusion about the short from one side to the other.  I am not sure how you could use diodes to correct that.  But I do have another idea.  I haven't seen your switching system yet but if you could separate one side from the other by using two contact pads and use a wider brush that would contact both pads at the same time then you would only have the two sides connected when the brush was feeding those two coils and the rest of the time they would be isolated.  That is only slightly more mechanically complicated.  I have seen brushes used like that in industrial equipment.  I also worked on an old Jukebox that had contacts like that.

Hello to All,

Ok, related to the site outages, it's been solved, we migrated the entire site to a new host server last night, so, no more interruptions.

Related to Figuera Discussion, yes Citfta, diodes are never going to work here, discarded...so, previous setup also had leaks and actually kept all coils on during operation...so it was not going to work either.
Now, I can go back to original disclosed method, which collapse all coils in the sequence, once that it reaches the end travel...this shows, as Cadman previously stated, a steep, vertical fall, not at all smooth...and I did not like it either.
The Retraction Stage should be smooth when going down, as also when is going up (Gain Mode).

So, by looking at all my already wound coils in heavier gauge (14-16)...in order to save time...I found one which has 4 inches length...and it is not that thick because it have a core of 1 1/4 inch.

Remember, that the starting point to build your Generator, is to start by designing the size (Length & Thickness) of your Secondary, and of course, that also have a pretty good number of turns/layers in order that Output be High enough...

So, on this 4-inch-long coil, I can add Four plus Four set of sequential coils of about one inch each...setting them like before I had done it, meaning, overlapped, one group and second on top...

Or I can also use an "alternating way" to set them, next to each other's, and of about 1/2 inch length each.

And here I want to add a Special Recommendation:

You do not have to be bound, constrained to the "exact build" as the Design that Figuera did back in 1908...meaning, on the number of sequential coils, or the way that it looks on his figure on patent...after all Figuera wrote..."this drawing is shown just for ELEMENTARY UNDERSTANDING of the whole idea..."
Please, free your mind from all these restraints!!...as long as the essential idea prevails, that is the only part to keep intact...all the rest can vary...remember, You and only you, are the one that restricts your way of thinking!!

So, here I will bring you a "new arrangement", where I do not have the sequential coils disposed as one group on top of the other, or overlapped, like I have shown before, but instead, next to each other's, alternatively.
What you must have in mind, is that the GEOMETRY for Coils design CHANGES, according to each method.
For example, on the overlapped method, the coils on the sequence need to be built longer and flatter in shape.
While on the Alternated Method, is the opposite Geometry, Coils here are as Thin in length as possible, (simply because you do not want to create a huge Gap between them, or else, formed Magnetic Field -between coils- would not be as strong, as when coils of the same sequence are closer to each other's, and can grow in height as high as the length of wire (previously measured to desired resistance) plus turns, take you...

On image below diagram, I finally have a smooth downfall on both Sequential Coil Groups, and they alternate, reciprocating every 180º. And I am using the jumpers across the commutator like Figuera had it originally on his 1908 Patent.

This Drawing explanation:

First, All Coils on each sequence are connected in SERIES, between them, as I also had them before.

According to Brush positioning, and rotation direction, Blue Primary N(1) is ON, and as brush moves it will start energizing Coils 2, 3, 4, sinewave is ascending, staying two segments on position 4 (Peak), from here sinewave starts the smooth downfall, as Coils order descends to 4, 3, 2, 1 in sequential fashion. While Red Primary S(5) and all coils on its sequence are OFF.

After Brush passes comm element #4, it starts energizing S(5) only...and as brush keeps going, it starts the Red sequence to turn ON Coils 6, 7, 8 or ascending sine (at #8 is the peak for red sequence), stays there two contacts/elements, then  starts the downfall sine, energizing coils the opposite way: 8, 7, 6 and back to Primary S(5) to

So, this is another build that I am starting, which is much simpler than previous one, that had 16 coils...

Any comments, opinions are welcome.

Thanks

Thanks, Citfta for all your great suggestions!!

Yes, I know... diodes are not going to work to solve this issue...and I do understand about making two commutator rows with one brush for both to keep separated coils sequences...but

at this point, I rather do not start taking apart my rotary switch, to make radical changes...but to work with what I have so far, to make it work...as I have shown on previous post.

This new design is much simpler related to number of coils used...and whole size of Secondary...

Ok, finally...

And after all, Cadman was right!!... about using the 32 commutator elements, to be able to sequence all 16 coils (8+8) according to the latest Diagram-Design that I have shown on previous post...

Concluding, that these type of sequencing, using the jumpers plus in order to have a smooth downfall, it needs to be done -at least- in 90º steps.

Hello to All,

Ok, on next post I will be showing a different method to just wire connect the sequences on the same setup I posted previously, or the Two Sequential Group of Four Coils each.

The Commutator design part, I think is flawless now... ...As I could not find any leaks, or short circuits, and I now have a smooth ascending as descending signal 

But, wiring it to the sequential coils in FULL SERIES CONNECTION, as I have previously presented since the beginning, and the way I have tested the first working setup, it had some issues, I was always concerned about:

Since it is based on a pure series connection, with a single/common negative, that serves to ALL Coils on each sequence, and that is connected only to the First Coil or the Primaries (N and S) this have some critical errors, that I verified with the first prototype I built and tested.

1- The Primaries take "All the Heat" during operation, they work as the warmest coils on the whole sequence.

2- Since it is a Full Series Connection, Currents keep constant during operation, BUT, Voltage drops, as it develops towards the end coil on the sequence, PLUS, this end Coil carries all the Resistance added from previous Coils on the Sequence...AND, this is NOT good at all!!, simply, because that end coil, barely powers on, it keeps extremely cold during operation, and it DOES NOT show a STRONG Magnetic Field, whenever observed with the Magnetic Viewing Film.

I want this END COIL, to be the STRONGEST on the whole sequence!!...Just because this end coil is the one at the very end TRAVEL of the Induced or Part "y" TOTAL LENGTH, and if we achieve that this end coil is the strongest on sequence, it will establish a very strong link with the rest of coils behind, so the Magnetic FIELD SPECTRUM TRACE, would be all the way to the end VERY SOLID, VERY STRONG every time a FULL GAIN MODE (Ascending) is turned ON.

So, I found a solution...At least, I think so...
