Poor mans fume hood
I replaced my kitchen range hood with a nice shiny new one, after mice got in and chewed up the old, crappy one. Which left me with a dirty, greasy
old stainless steel range hood to dispose of.
But while it was sitting in my garage I was doing something a bit stinky outside with HCl and MnO2 ( aiming for MnCl2), and I realised that with a bit
of a cleanup I could have a free fume extractor over my bench.
After a day of disassembly and degreasing with sugar soap I had a reasonably functional rangehood again. With a 125mm hole bored through a concrete
wall (fun times), it was mounted and ready to go.
Internally the hood is stainless steel, with plastic (ABS?) ducting and fan, and a shaded pole motor (no sparks!). Not exactly chem lab grade stuff,
but good enough for the few things I do that might stink up the house - like solvent welding plastic, solvent cleaning, or painting.
And I no longer have to pay to dump an old appliance.
