These are my new coils made in a hurry because I have no time... These are long, I have to cut them.

Lamazoid_ How you make vacuum? With the water system? I think in doing to Yes i bought glass vacuum pump (aspirator) from chemical store. Then i attached it to vacuum chamber (glass can) through valve because it should be disconnected from the pump when the water turned off (otherwise water will go in the chamber) It looks like that:

Underall like this bobbin? Lamazoid cannot see the image. Gary, is possible to obtain a bobbin of an output of hv? like a flyback (in our stun guns)

I Don't quite Understand.
A Flyback transformer is not really any different in design, but the drive circuit is different. And you will get Higher Voltage using a flyback design, But Much LESS Current.
Not really what you want in a Stun Gun!
In Addition, In your picture above, It appears that your Ferrite Core and primary winding Fit LOOSELY into the Bobbin.
IDEALLY there should be NO Excess space between the two. "It should fit Tightly to get the best energy transfer".

The Ferrite Rod Must go under all the windings on the secondary to have good efficiency. Yes Sir, but perhaps you do not understand my question, UNDER ALL like in my first coil thick wings? (Primary and secondary are windings on DELRIN together) or the secondary are winding in the DELRIN and the primary wind on the ferrite bar. Thanks! ;D

Hi Ivan, Yes I see that. But its important that the Ferrite rod with the wire wound on it, be at least the Same Length as the coil wound on the Delrin bobbin.
If the coils on the Delrin rod Exceeds the length of the ferrite rod and its coil, the secondary Doesn't pick up the magnetic pulses. So that part of the coil Won't work.
AND PLEASE, My name is "Gary". I Dislike SIR.

Hello Gary, I know that the ferrite core should be as long as the secondary coil, but thank you anyway, it would be a serious mistake to make a coil with short ferrite core , winding it, isolate it and then not work. Lamazoid your vacuum pump looks good, very practical, but has enough power to remove air bubbles from the EPOXY? I ask this because the EPOXY fluid is a very heavy and it takes a lot of power to extract the air inside the coil and that fluid penetrates between wires

I ask this because the EPOXY fluid is a very heavy and it takes a lot of power to extract the air inside the coil and that fluid penetrates between wires If you use a "Slow Cure Epoxy", that pump should work perfectly fine. (Typically a 24 Hour Cure) But don't retain the vacuum for Long periods of time. That causes the Epoxy to self gas. I Draw a good vacuum and retain it for about one Minute, than release it. I repeat this process about 3 or 4 times. This will result in Good Penitration. PS: I can't watch Any Videos, as I'm on Slow Dial-Up internet. Take care.....Gary

Sorry i can't watch this, like Gary i'm having slow connection. Maybe you can compress it with Dr.Divx or another software ?
Bt the way, i forgot to say about another way of making powerful stun gun - Marx generator. This was even patented by Cover (Taser's inventor) as high voltage source for stun guns. But it had no application at that time because of big sizes of caps and gaps. At now this is not a problem, so you can construct a compact marx-gen in handheld weapon dimensions.
