Washing machines have an inner (spinning) and an outer (watertight) drum. I plan to use both for my firepit, which should allow it to be smokeless and also mitigate the "it gonna get HOT" problem.

(I haven't actually made it yet because my outer drum has some butyl tape or something I need to remove first. Anybody know the best way to do that?)

    Fire! Remove the tape with fire!
    ugh, sorry, I forgot it's the dull mens club, then I don't know.

    I've considered it, but (a) it's the outer drum that (I'm hoping) won't get very hot, and (b) I'm worried that burning it off would leave a residue.

    There's nothing much insulating the outer from the inner, so it'll get as hot as the fire, just with a small delay. Putting in some type of insulation would reduce that, but that complicates things and I have no idea what would work that wouldn't eventually become a fire hazard. Asbestos? lol (don't do that)

    In theory, the design of a smokeless fire pit creates a convection current where cool air keeps getting drawn into the cavity from outside the fire pit. I'm sure the outer drum surface won't be cool, but it shouldn't be as hot as the inner drum either.
