Before beginning the project, I needed to figure out what features I need to have in the mechanism. So I 3D printed some pieces to hold on to the core so I can experiment with winding a coil by hand on a lathe. After a couple hours of winding, and unwinding coils, i figured out I needed at least two moving parts, one to rotate the core, and one to move the wire horizontally according to where the wire needed to be wrapped. With those design limitations I began designing in Inventor.
