Cheers Mike. Mike, I have re wound quite a few toroids, see also my old 'tinker' threads. This was actually quite enjoyable when doing it the easy way. If you read many of my posts you will see it's a learning curve that I, like everybody else went through. May I suggest you forget about the three stack idea. With a tall narrow 'hole' it's difficult to keep the wire flat against the hole wall as you must to avoid running out of 'hole' space for your primary. A two stack from 2 x 3KW Aerosharp cores is as much inverter as you ever want, it can start and run amazing loads. These home built inverters have come a long way since 'Oztules' early Power Jack experiments. I have gone along with the new ideas as they came up, the early inverters had a nasty habit of blowing Mosfets for no apparent reasons. My inverters have now all been updated to the opto isolated version, this has proven soo much more reliable than anything that came before. Have fun.
