For a project I am working on, I need to heat a roller.

The roller in question is a tube about eight feet long, horizontal,
about five inches in diameter and .049" thick aluminum wall. It turns on
a 3/4" axle and is supported on three spiders at the center and ends, so
that air can flow through.

The whole machine is always indoors, in ~70F room-temperature
conditions. For other reasons it can't be used in drastically colder
temperatures.

I need to be able to heat this whole thing to maybe 120F to 150F,
automatically. That is, I want to set a temperature and forget it. The
wattage I am guessing might take 1000 watts, and it must be electric
(dry) heat--propane will not help, as it gives off water vapor.

Aim a hair-dryer down one end of the tube.

It took _six replies_ before someone figured out a mapping between "UL
Listed thingie that delivers 1000W at 150F and has a fan" and "hair
dryer". Good for you, Paul!

It was quite an intuitive leap considering that I have no other use for a
hair dryer.


Or hair? ;-)
