Dear Barry,
Very verry interesting.?? Sounds to me that coil form is a winner.?? Where did you buy the thread bobbins??? I am in the hunt.?? I am putting a test fixture together today so I can start testing materials.
but you may have hit on the most desirable form for the coils.
Take care and have fun. Thanks for sharing.
