I wimped out and bought a steam cleaner - hoping to avoid making my own
steam source for a small steam box (for bending a cane handle).
But the capacity is insufficient.
The good-right-and-holy path seems to be a sizable stainless pot with a
top on it feeding one or more dishwasher hoses..... sitting on an
electric hot plate.
The idea being to load the steam generator, turn the hot plate on, and
then forget about it for a number of hours.
The auto-shutoff comes in if/when one misjudges the amount to water
and/or forgets to come back soon enough and the pot boils dry.
Does anybody have experience with electric hot plates in a situation
where the plate needs to shut itself off if/when a certain temperature
Google turns up a number of possible solutions, but I am not clear on
exactly what situations they address.
