I took a closer look at this large U-shaped transformer and it turned out to be an aluminum winding    I have to find another one.

The first winding was covered with varnish and then wrapped twice with thin Kapton tape. I put quite a lot of it because the gaps are quite large, it takes a long time to dry, but I think it is enough to stiffen it.


Now I winding the second layer. The target is 223 turns per layer
