LAURIE!!!

it's the resistance in the wire that causes the heat.. so I'd figure to maybe add a resistor before the nichrome to drop it so that you can use shorter lengths and keep the temp down. Maybe even a small Pot would work.. and you'd be able to control the temp that way from zero to hottish worm. I wouldn't know where you'd put the wires though on a refractor, probably wrapping it around the outside of the tube where the lens is.
