Hubbard coil

power cores.... eh  hummm

i like your design

are those cores pressed or how would one go about  makeing them?

ist

It is not like Ferrite - its just pressed iron powder with additives and then heat treatment.
You can cut it with common cutting tools - its  easy to mill, turn on the lathe,  drilling holes ...
The best tools for cut it of course  are carbide bits, mostly they have 1/8 shank - as higher RPM as better (I use 25.000 .... 40.000 RPM),
Bits like Irwin 1/8" Carbide Ceramic Tile Drill Bits - Rotozip eBay Item number: 360071718108 - when bigger cuts and holes,
or smaller one like 1.90mm carbide router burrs, diamond cut   Item number: 180167291446 when smaller works,
All coming grinding/dust  I do collect , its useful when mixed with epoxy and molded ...

I'm curious about all the poeple that wind coils here. Do you wind them manually? Because that seems like one hell of a job. You maybe want to consider to invest some time into a homemade coil winder to save lots of time down the road. Here's an example...

I guess for toroid coil this is a must! http://www.youtube.com/watch?v=98q4Ic6UL7c&feature=related

Howdy Broli,

It is hard work that tempers the soul.  Once you get accustomed to winding, its an automatic action.  You can think about other stuff while you hands do the winding.  Plus there is a great sense of accomplishment when you are finished.  I wound 18 coils for the Infinity Coil...

Blessed Be Brothers...

@Khabe,
Great pix.

@Broli,
I manage my time and resources to wind by hand at work or on the back deck with the wife and dogs while watching the sunset.
Can't let the addiction run my life too much.

Tonight I move everything to the real bench to hookup.

I am also making a hydro-kinetic impulse generator (electrolisis) for the conversion to on-demand hydrogen with my truck. $60.00 for 30% savings.

no on eis going to build this?   If you are waiting for the "How To Guide" - forget it. 

I told you exactly how it works.  It ain't rocket science.
