I am sure that would work. A lot of the fun and sense of achievement I got in my teens was actually winding the coils, making a core out of lengths of iron wire, making a brass spring / steel interrrupter arm etc. The finished winding was put in a vat of molten candle wax to increase the interlayer insulation. I doubt if soft iron wire, 36 s.w.g. enamelled copper wire is readily available nowadays. Oh and also made a polished oak base .
