That e-core I have came out of a 48 volt forklift battery charger and I'm now on the hunt for some wood to make the former so I can wind the secondary in my lathe. i'll just setup both wire spools in line on a supported shaft and put an old touch counter on so each jaw on the chuck will index it. So 4 counts a revolution and as each side of wire is layed I'll give it a tap with a leather hammer to get the wire nice and straight as the secondary will need to be wound pretty tight to allow the primary to fit in the slot.
I do have enough 16mm cable left so that will be used for the primary and it will be an easy task to swap the toriod out for the E-core one.
I do need to learn what measurements to take so when the transformer is swapped over the results can be compared.
Now with that huge E-core in that 300 amp mig welder being a figure 8 configuration I'm wondering if all 3 sides can have their own windings so 3 sets to join which in theory give a heap more power.
