Re: Winding BiTT with C shape winding tool

Hi Ole
 I think the drawing of the Thane transformer is not quite correct, as I assume the circles represent the three coil windings, and the rectangular boxes represent  the transformer legs "reluctance" as you call them...:"nagnetic paths" might be another term to use for those boxes and it is important that their magnetic-resistance fo magnetic flow  ("reluctance" to flow) should also be included in each those boxes, as they all are not the same resistance to magnetic flow, some paths have skinny transformer legs, some have much thicker transformer legs,
 For example the large rectangular box in your drawing i in my Bitt core made of florist wire, is three times thicker than the rest of thoise inner transformer legs. 
 This is the advice that Gerry gave to me a couple weeks ago, since you want to make sure that the magnetic flow has a very strong path to the opposite side secondary....So I added three times the number of florist wire lengths to my core "perimeter"  and it is three times thicker 
 Tthere should also be three more rectanfular reluctance boxes in the drawing, each underneath the three circles representing the coils, this regardless of the thicknesses of the cores, it is just something missing in the drawing.
 

 MAybe most important or just as important as including the reluctance value to the relcutcance boxes, is that there is, I count six "three-way" junctions to the Bitt transformer core drawing, while the Jensen has only two...at the top and the bottom of the primary...
 

 And the three way junctions being excluded are actually the most important detail of the BiTT transformer! As those two outside three way junctions on the left, and the other two on the right are where the back-currents "Decide" which route to take, and that is, back to the primary and reflect as extra draw and never overunity, or back across to the opposite side secondary, where the power produced in the secondaries becomes additive-power (coherent?)
