I want to make 2 identical unifilar pancake coils, with a phi ratio hole, and distance them and fill the gap with epoxy (as a good dielectric)
what should the distance be? the radius of the hole? or the diameter of the hole?
the epoxy resin can be poured in. a mal (casket?) should be made around the first coil and the epoxy poured in and hardened. then the small layer epoxy again poured on top and then the second coil is placed on top. the coil is then hardened out.
the epoxy should not fill the phi ratio hole.
baking oven paper can be used to build the form. and a silicon spray can isolate the epoxy from the paper.
the coils can then be connected in series into a side by side bifilar. the connection can be made with a capacitor.
i can use speaker wire, but i also have a roll af some rather thick enameled coper wire for this. but it is stiff, and will need a guide to roll up into a proper phi holed pancake coil.
I also have some plates of a induction stove.
they are ideal for this job. allready formed. flat multistranded... unifliar.
lets build this. Im open to suggestions in this build.
