    Secondary Coil Winding

    The secondary coil is made from a pre-cut piece of ABS pipe, two end caps/plugs, a spool of magnet wire, and some clear polyurethane. I pre-coated the pipe section with polyurethane then wound the magnet wire before it dried. Despite mounting it on a lathe, I hand turned the whole coil.

    When complete, I sealed the coil with additional coats of polyurethane and a clear spray sealant. It was wound with 26 AWG enameled copper wire, I estimate around 1000 feet were used. I don't yet know how many windings this actually ended up being, but I will figure it out by my next update.
