Winding a flexible form like that, with no possibility of holding it in a drill chuck or similar, must be good for exercising the arm muscles. After winding my original 73kHz loading coil my arm ached for a few days afterwards.

Hi Chris,

This wire (exactly this piece of wire) has been used for the first
version of the 900m long ground loop antenna some moths ago. Earlier, it
was part of my large 6.1 H coil that i used on 2970 Hz in the beginning
of 2016 :-)
So it is recycling. Mother nature, you know...
