Little tool for the winding of toroids

During the building of my K2 I was facing some troubles to wind toroids which 
had sharp 
edges grinding the enamel of the copper wire. 
I would like to suggest you following trick which I used with success.
See link below.

All you need do is to take off the sharp edges with a countersink bit.

Michel,

That is a great tool, and I am certain many will appreciate it.

There is a technique that avoids the problem - and that is to form the wire
around the OUTSIDE of the core with a finger on each turn.  By forming on
the outside, there is not as much need to pull the wire to tighten it.  It
is in the pulling act that the wire is scraped.
