Update....It works...!!!And I note that the size of the wedge determines the "coneniness" (yes, that IS a word...
) of the cone....
Actually, the tighter you wind the face of the cuts, the conier it gets - a simple cut from centre to circumference will work, too, although winding too tight could cause some puckering at the peak of the cone.
You could also build pyramidically-shaped smoke collector hoods by cutting and assembling four triangular pieces - sheet styrene would work well. Make them with the opposite sides as identical pairs, with all mating edges the same length. Vary the lengths of the lower edges (again, in pairs) to create rectangular-bottomed pyramids or make all four triangles the same dimensions for a square-bottomed hood.
The exhaust pipes through the roof can be round or square for either cone- or pyramid-shaped hoods.
