Greg and Kevin

My latest coil is 17.5" in diameter and 24" high. Its predecessor was
14" in diameter and 30" high. Both were wound with #16 machine tool wire
at 8 turns per inch. Therefore the first coil had 192 turns and the
earlier coil has 240 turns. They were purposely made to have the same
wire length. Hope this helps.
