I've previously used Al Sheehan's fantastic dew heater shield resistor usage guide to make several heaters for my 12" SCT, 66mm guidescope as well as for several eyepieces. The technique I used to construct these has led to dew heaters that are a little stiff - especially when cold, because I soldered adjacent resistors together in a ladder pattern by using the actual resistor legs themslves.

I thought about changing this so that I could have a more flexible arrangement and came up with the thought of using solder wicking braid as the two parallel power bus bars. Much neater, and works a treat. Nice and flexible, even encased in heatshrink tubing and reinforced by a strip if 1.5mm plastic strip 2cms wide.
