I would like to improve the smoke output from my postwar and MPC era steam locomotives. I read through the Forum threads on how to do this. Basically, enlarge the air hole, change the batting material and install a low ohm value wire wound resistor. I recently rebuilt an American Flyer smoke unit for a friend. Used a Tiki torch wick and wrapped the wick with Nicad wire to get about 25 ohms. The locomotive smoked great. So my question is what about wrapping some Nicad wire around a 22 ohm copper wire wrapped resistor. The Nicad seems to get hotter than the copper wrap. Or am just barking up the wrong tree here?
