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.
