I was rebuilding a couple of Vintage Flyer Smoke assemblies. One had burned out titanium wire and the angle hair was black, I cut it out, pulled some hair up and wound in the bottom. then installed a brand new Lionel 27 ohm heater. Man it smoked like crazy, then it was out of fluid. so quick I thought. I took it apart to do some checking. That dang heater at 5 volts is over 200 degrees, at 10 volts its up to 280, then at 15 volts it was nearly 400 degrees and red dang hot!!!! I happened to have a voltage regulator I throw into the mix and cranked it all the way down. It limits Amperage at 15 volts to .5 A and the heater coil never went over 220 Degrees. At 5 volts the heater was at 185 voltage as amperage was up to .75. So this is a solution but the regulator is like 5 dollars.
Anyone have a good idea how to get nice smoke at low volts AND higher volts? Or a cheaper regulator if that is the answer.
