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 Edited 2024-02-24 06:07 by -dex-
