I agree with the heater element idea, craig. A little like the dust pan handles we used to make in metal shop made from 1/4 or 3/8 in. rod bent over on itself and attached under the pan with rivets. Greg's picture with the dashed yellow box showing the area of the object still shows something sticking out from the rounded thingy, but the picture is a different scale (smaller) and I can't bring it up to a decent size. Maybe someone could enhance it so the pixels are more smooth.
Where's my pictures of the flare and starter cartridge for comparing to can1 and 2??
