John. a simple hand winder with 2 (2x4) wood frames and #16 nail spindels
works fine for small coils ( 4 x 30). An ice-cream-frezer drive motor makes
a good electric drive motor for winding coils. If you want to fo first class
buy a metal turning lathe. My frezer motor cost me $3 US at a thrift shop.
