Hi Mike, we often made formers from fibreglass sheet, but if you tried to wind a heavy winding on them they would collapse, so the wood went in the middle and then the fibreglass former and winding would be slid off the wood.
I didn't do too much transformer winding as such, lots of little coils, and plenty of electric motors. The workshop where I did my aprentiship was soley involved in motor rewinding. From clock sized things up to a few megawatt alternators.
