I remember his technique, and I had many a chat with him about it. The
first windings would go on very slowly, and he would guide them
tightly alongside each other with a piece of polished wood. Each
winding would then be hammered down. He explained that it was
transformer death to allow an air gap in there - it would make the
windings buzz. Each layer was topped with kraft paper, then the next
was started.

Did the paper go between each actual winding, or between each interleave?
(I'm assuming that an interleave can have more than one layer of turns.)

It went between every new layer where wire touched wire..

Oh, and take some time to plane a piece of wood that fits snugly
through the centre of the former while you are doing all this,
otherwise you will smash it.

Good point.
