i have 2 running versions so far.. the third version will be my first bifilar winding on a larger, about 1/2hp to 1hp (pressure washer) motor. its almost done, and i have all the supplies to begin learning to accurately measure with a de prony brake. the 4th and more challenging motor i am working on is a modified ceiling fan motor, if that one works the way i think it will it should be very interesting. i will upload a summary video when i have finished these 4 motors.
but right now i am hitting a road block
so far i have been useing the existing rotors in a modified form while trying to find a place to buy the right kinds of materials to build new rotors with.... this has been quite vexing, i am looking for sheet material to make laminations from. i have googled various terms for motor/transformer laminations and it seems theres a much bigger variety metal than i thought. commonly called "electrical steel" but a whole slew grade terminalogy. a local metal fab shop in town with a laser cutter has sheets of astm a36 cold rolled steel which is not considered "electrical steel" and other companies i talked to on the net have told me they think a rotor made with that kind of metal would get really hot! i called a local metal supplier to talk to there metalurgist about it but he didnt know anything about the magnetic reactions of diferent grades of steel!!
so he wasnt very helpful. the best information i found so far came from, national material company Home and (various other companies refered me to) tempel steel Tempel Steel. both companies dont generaly sell to the retail market so a minimum purchase is set at around $500... yikes! to peter... i noticed in the dvd you refered to something called solectron laminations?? but i came up dry when trying to google that. can anyone give me some advise on how to select a "good enough" material and where i can buy it without needing to buy gobs of it? or if i do need to buy a whole bunch all at once i dont mind.. i have a variety of "from scratch ideas" but... i would at least like to know i am buying a type of material that wont completely fail on me by holding on to its magnetic field too long!! any help would be much appreciated!!!

The thread has not run out. I am just waiting for my DC treadmill motor to practice in dynamometer measurements. Then I will be certain, that all my calculations and measurements are correct. Also I am still busy with my non free energy related project, but that is about 90% ready. Maybe I will make a thread about that after it is finished, it will be funny
In the mean time I am working on that water spark technology and am eager to test this on a car engine. I must apologize that I am jumping between projects so often. It is just that I get a boost in enthusiasm randomly and every time the enthusiasm is about something else and I have to make a use of it, because when I am on such an boost in creativity, I can move mountains
