These are bifilar wound pancake coils using 35AWG heavy build wire.
These coils made on my v3 winder. The large coil is made on a CD sized “blank” piece of plastic that is typically included in a bulk package of CDs. I used this as a substrate because it is thinner than a standard CD and has no aluminum layer. The large pancake coil is 4.98mH air core.
The two smaller coils are made on a miniature CD, which fits perfectly in a flyback transformer core. These mini pancake coils are 4.93mH in series (air core), and 96mH on the flyback core.
This is a quick and dirty method to make a spring in the home shop using just a drill press and piece of dowel. NOTE: this method can be dangerous, so safety and precaution is of utmost importance. Using spring wire or music wire and a low-rpm (200 or less) drill (or lathe), it is easy to turn a compression or tension spring using a dowel / mandrel!
