Hi Garry, Referring to the old and honorable (780kB suitable for framing) chart at: http://216.160.168.190/TeslaCoils/Misc/WireGaugeChart.jpg #28 enamle wire is 72.7 turns per inch. 30 inches is 2181 turns. 6 inches in diameter gives 1.571 feet per turn so you have 1.571 x 2181 = 3426 feet of wire plus about three. Well say 3500 feet... The chart says that 2067 feet of #28 weighs 1 pound. So two pounds should do it. I checked with some other charts too and it basically agrees (no two places make wire exactly the same). So I would get at least two pounds. You can always cut it shorter, but you can't cut it longer ;-)) Cheers, Terry At 04:21 PM 10/1/2000 -0700, you wrote: > > I am figuring on going to a 6" secondary wound area would be 30 inches of #28 > awg wire. > > Anyone know about how many pounds of wire this would be?
