did harvey ever make that oxide core device?....what do you think about the OU thread?.....goodstuff.....TODAY IS THE DAY OF DISCOVERY!

But if you want only the cores that are not magnetized, they will cost you just 30$ a set. Unfortunately shipping of those cores to my country costs 3x as much as the cores themselves. I need at least 2 sets for one complete 24 pole ring for my tests. I will get them grinded to precise shape so that there is a great touching area, this is important according to the channeling info. And then I will put them on a rotating wheel and lock them. Of course I will have to magnetize them first. So far I have not found any suitable material here from which I could cut out the V shapes, because the needed steel grades are obtainable only in un hardened form. And the hardening process though which the cores gain their magnetic abilities is quite tricky, you need to cool the parts quick, but a bit too quick and cracks will appear. So the cores from the FordT is so far the cheapest way for me.

the mag roller in that DV unit is a special type of field shaper that pushes the magnetic field into a unidirectional brush and I don't want to lose that assembly.
(I had it as a pipe wrench leverage extension with my plumbing tools). Wouldn't be the first time I sacrificed a 'tool' in the name of science
