Your set up is excellent for an induction "torch" . Not a traditional coil. You can use ferrit inductors from Fluxeon. I built few annealing machines using step motor driven arm, delivering the brass in and out of the magnetic field. In addtion to ferrit inductor It requires very few components - ZVS board, 750 watts powers supply, timer and a contractor (or a good quality Solid State relay). At least you can anneal a lot easier your own brass.
Good luck
