The Secondary on my current coil is wound on 10" PVC Pipe. There are a total
of 1150 turns of 0.9mm Copper Winding Wire on the coil form. This gives an
inductance of 60mH. The Winding Length is 1040mm. The ends of the PVC pipe were
sealed with Perspex discs after the form had been fully baked. There is a total
of about 1litre of varnish covering the secondary coil.
