@serialkissersband It all depends on your application. If you are thinking of a Tesla coil then no, bifilar windings are not designed for that application.
@78chuck You mean "aren't these 2 wires supposed to be wound with a ratio in mind"? You may be referring to Litz wires. Please see my response to usedbandage9
In some of my research in coil winding I found that if one touchs the wire that in time the acid remaining on the wire will brake down the insulation and make your coil useless.
@abpccpba Thanks for your comment. I've not found this to be true so far. Some of my coils are several years old. Their impedance remains pretty much the same today as when I wound the coils. But what you say might be true (it makes sense as we all generally have a very thin layer of acidic coating on our skin). So perhaps I'll use cotton gloves when winding my coils. Once the protective black electrical tape is wound on then I don't have to worry about acid from my fingers.
@usedbandage9 Thanks for your comment. For my Bedini projects a parallel winding works just fine. Twisting the 2 wires together *before* they are wound onto the spool is called Litz (lookup LITZ in Wikipedia for more info). In Bedini replication circles, there seems to be some debate about whether or not twisting your wires before winding on to your spool is more effective. Some say yes, others say no. I've not tried to determine if there is any impact in my projects.
It looks like when you began, your wires were approximately on the "bottom side" of the spool, and as you rolled the crank, those wire "broke over" the top, first... as opposed to "going under", first, correct? Thanks
@KyleCarrington Thanks for your comment. Correct. Yes, the second "layer" goes over the top of the first layer as you continue to wind (it's impossible for it to happen any other way).
For pulse motors this is great way to make the bifilar. If you are trying to make an inductor there is a little bit more precision and math that needs to go into it. In regards to mH, inductive reactance and capacitance the coil may hold. Not even counting the resistive measures if you were to build a SMeyer equivalent w/step-up and bifilar combined.
Good video. Glad to see people showing standards. Really makes for a better collective effort towards a lot of our goals on here.
@john29302 Thanks for you comment. Bifilar coils are not for every project that requires a coil. Some projects require just a single wire coil, some require a 2 wire coil (bifilar), and some require a 3 wire winding (trifilar). Bifilar coils can be used when you need a transformer-like arrangement in the one coil (energy down one winding gets converted/shunted to the 2nd winding). I use my bifilar coils for various Bedini projects.
Just a thought but shouldn't the bifilar be wound on a toroid bar and mounted in a steel plated magnetic coupling? Like the one inside Stan Meyer's rotary controller unit? I guess if your using a Vic circuit you can just use bobbins as the charge is already polar magnetic and will create its own magnetic field as it travels through the coil.
@pkrska In my experience the performance difference between a "messy" wind and a "neat" wind is negligable.

Aren't these two coils supposed to be wound at a ratio?

Does it make a difference whether the wires are twisted or in parallel? If so, which one would make the wheel spin faster?

wow man you can reverse directions and overlap the wires....thats amazing....not sue bifilars are efficient or what?

@freeenergy4everyone Toroid coils can be bifilar - yes. For my application (Bedini replications) I just need a bifilar coil as I've demonstrated.

yeah like jetijs said... please upload a video on how to make a core.
it would realy help me a lot:P

i like that very good!!!

Nice video. :)
Maybe make also a video about how you make the core of the coil and how you hold the electrodes in the core together in place. :)
