You beat me to it.
I just watched the video.

I am encouraged to see another configuration besides sine wave peak alternator.
In this new configuration he is no longer using a sine wave peak commutator and relays.
I would like to learn more about the differences, the pros & cons, of sine wave peak versus toroid generator.

I do intend to get more assembly work done soon.

Good morning Thestone and Scorch........Q3 is born. I am working on my replication of Q2, that take a lot of time, I am late .....step by step.....

12:10 there is the bingo moment. Shorting of toroidal generator did not afected much pulse motor but when vacuum pump was attached its motor was running. The toroidal generator smells on what N. Tesla was doing... Someone need to pick this up and see if more energy can be generated than energy was needed to rotate magnet inside of ring. The most important bit there are coils arrangement to 90 degrees than you expect on conventional generator and plenty of iron to weaken Lenz force.

Just a side note-

Quanta Magnetics did send replacements for the missing shims, and adjustment nuts that weren't threaded all the way through, which have arrived today.
So all is good. 

And there is a new video that shows a very interesting effect.
Depending on where he moves the 'timing' of his switch, there appears to be a significant increase, or "Toroidal Power Amplification", in power output from the toroidal generator.

I sure would like to learn more about toroidal generators and these switching effects.

Coil shorting was explained by Ismael Aviso very well - http://youtu.be/rv7C7YOetDY?t=29m26s
Also in regards to toroidal generator seems nobody pay attention to what it does when generator coils are shorted for longer time... The conventional generator would be dead stopped already while toroidal generator gets only small fraction of Lenz force back to magnet there - http://youtu.be/Zu4pzvkSkzo?t=12m10s

I replaced the black, ferrous, cap screws, in favor of stainless steel studs and nuts, so both ends of the assembly now look uniform.
Also completed a major portion of the wiring.

I decided to solder all connectors because, sometimes, crimp-on connectors do not, always, work well on solid wire when using a typical hand crimp tool.
Even my compound crimp tool tends to leave them a little loose sometimes.
Solid wire just doesn't like to be crimped. Too tight may cut into the wire; not tight enough and the wire may become loose resulting in intermittent connections.

Also drilled, and tapped, a couple new holes in the bracket and installed a terminal strip.

That is all for now.

Completed the timing disk and reed switch.
Some of the cap screws, which are supposed to be stainless steel, turned out to be regular steel.
Suspect they got mixed up in the bin, or box, before parts kit was assembled at the manufacturer.

Fabricated a mount for an ammeter.
First test of pulse motor section - Running at around 400 RPM at 300 ma. and 24.9 vdc.

Still need to build other stuff but first test run looking really good and seeing around 27.5 vdc at the BEMF output with no load and meter measurement only.

See part number: T650-52

They make larger cores but they do get pretty expensive.

Hi Scorth,
Do you can say where you find thr toroid core, please.
I think finish the mecanical support for my replication of the Q serie the next week, like you can see on the pictures I have somme work before the first test.
Thank again to share and put somme life in this topic, Marc

Ran into another fit issue today which has brought assembly progress to halt.

The kit did not include a critical part needed for sine wave peak switching.
The commutator required to accomplish this is to be fabricated, from local materials, including the insulator and copper contacts.
This part is based on an aluminum hub (included) to be used as the base, and mount, for a commutator which is supposed to be built from a spray can lid and copper strip contacts.
I did order some copper tape from amazon.com and, hopefully, that will work ok.

But what has become a big fit issue is the insulator which should have a smooth surface, fit the hub tightly and evenly, and be able to fasten the copper contacts to it.
The instructions read: "A common spray paint cap (smooth) works well as an insulator for the 2.48" diameter hub. . ."
But this is where the problem is. I have LOTS of cans but none of the caps actually fit including paint caps.
Most are too small; others are to big and none 'work well' . . .

Have already destroyed several caps tying to make them fit.
Have tried heating them so they might stretch a little but this merely caused deformations instead of a uniform 'stretch'.

At this point I am stuck until I can find something that actually fits and, hopefully, has a half way decent, smooth, surface for the copper tape and brushes.
I will go ahead and send a request, to quanta magnetics, for a solution and, hopefully, they will have some suggestions, or materials, I can use to move forward.
