(2 ) .374 rare earth magnets, a piece of copper pipe, epoxy putty, brass crimp, shrink tube,some solder and I am ready to go! I cut open the copper pipe and then pounded it flat with a hammer and anvil to make a sheet of copper plate. Cleaned it up and scribed a .375" circle with a handle (think lollipop shape) I glued 2 magnets onto the circle. I then bent the stick part around the magnets, to capture them. Drilled a hole in the stick, soldered the wire to the stick, slid a brass sleeve over it and crimped it, then i mixed up some epoxy putty up and encapsulate the entire head unit.Then shrink tubed the connection. Didnt have to leave the shop one time !!
