Many people only think about making from a fishing reel a coil winder. This coppercoil winder, for small coils, is doing the job very well. One turn of the reel handle makes four turns of the coil. You have to take away the bail, the line roller and the line spool from the fishing reel. From an aluminium strip you make a U-shape to attach to the winder with two bolts. In the middle is a hole for the central up/down spindle. The drag adjustment becomes the new spool holder. The wire guide makes evenly distributed windings at the spool. At top of the wire guide is a piece of printboard with holes for winding more wires parallel at the spool. The video speaks for it's own.
