Don't stress yourself Roger, there is only a volt or so difference between alternate turns, and the insulation on the wire is really excellent stuff. Nah, I'm not concerned at all  ...  it was really only in reference to my comments about how spaced out the wire is and that it could literally be wound without any adjacent wires touching at all. And that is the reason I'm not fussed about using second hand mylar  ...  because mylar is barely needed anyway. Maybe between primary and secondary  ...  but the thicker wire will have even thicker insulation, so probably not 100% neccessary there either.   Quote   The thick winding will go on easily.  The circles within circles software assumes rigid perfect mathematically correct circles.   The very fine multistranded wire with thermoplastic insulation is quite soft and easily deformable. If you put it in a vice, you can squash it flat fairly easily. So where one turn touches another, the wire can deform slightly and the whole mess can be squeezed into a slightly smaller space than theoretically necessary. So if the software says it will fit, it will all fit on easily with space to spare for a big central mounting bolt. I'm usually a bit optomistic and can be caught out sometimes so that's encouraging to hear. Last thing I want to be doing is unwinding some layers to fit everything in!!! I had noticed in looking at the display of circles inside a circle that they make no great effort to space them optimally. They place a full circle around the outside and then another inside that  ...  but make no effort to place the second lot into the grooves between the outer windings. I'm sure that would allow another turn or two if desperate. I just tried using a graphics program to place that second layer into the grooves  ...  but you can only get 2 or three per layer to actually go in the groove because of the smaller diameter  ...  so I only managed to fit one extra circle.
