This page is about how I made replacement coils for my grandfather's Heathkit GD-1 Grid Dip Oscillator that was passed down to me. A few years after his
passing, my grandmother found it in a drawer and gave it to me.

The completed coils.
All the materials needed to construct the coils.

Setting the pins to the coil form with clear epoxy.
Winding the wire to the coil form.
A finished coil!
