Winding Your Own Custom Choke Coils

  • Simple hand cranked coil winder with mechanical turn counter and adjustable feed tension.

Some coil form alternatives

  • Some fabricated coil form ideas. (Masonite, wood dowels, spools)
  • Remove any ferrous bolts from core hole before use.
  • Just count the turns; it's not necessary for the coil layers to lay perfectly.
  • Dipping the finished choke in varnish is a nice touch.
