Sounds cool.
I assume at some point you need to change out the steel
wool?
Probably not for a long time, if at all. Commercial steel wool is
oil-coated to prevent it rusting. Philip described his as going black,
which I expect will be the result of the oil carbonising in the hot air
stream. The result will be a tough coating of carbon that will prevent
oxidation. A similar idea is sometimes used for steel tools -- heat
until it develops a blue oxide layer then plunge into oil. The
resulting blue colour is fairly pretty, and rust-resistant.
