Developing the Bobbin

The next set of experiments required a bobbin to wind two coils , one silver and the other copper and wound at 90 degree angles to each other. First I rendered a proto bobbin to establish fit over the Vogel Crystal and wall thickness of the bobbin.

Then I received help on CAD design from Chris Essonne and a bobbin w/ wind guides for both coils , a Bottom Holder and Top Holder to center the Vogel Crystal’s C axis in relationship to the two coils was rendered .
