Winding wires to toroidal cores requires special tools and is also quite laborious. The proposed tool greatly simplifies also facilitates the manufacture of inductors on ferrite toroidal cores. First of all, you should make a paper ring of thick paper, soaked in paraffin. To do this, cut a strip of paper with a length of 200 mm, a width of 2-2.5 mm and also fold in half along the entire length to obtain a groove. Then this strip is passed inside the ferrite ring and also glued so as to form a paper ring.

Toroidal coil winding technology

For a future winding, a piece of wire is measured, wound on a paper ring, securing the wire end in the hole made in the paper ring. Coils of wire impregnated with paraffin also remove the paper ring. After this, it is allowed to start winding the wire on the ferrite core as if it is shown in fig. 1. Such a winding means is convenient in that it alienates the possibility of winding an impressive number of turns without damaging the insulation of the wire.
