Can any of you explain (in simple language, please!) the effect of the taper and length of the trumpet - I think I've been told that a longer trumpet will yield more torque, although if this is the case there's presumably a trade-off.
I'm just wondering what the downside of a pronounced taper would be - in rough figures, a 70mm diameter has twice the surface area of a 50mm. So could a solution to the mesh question be a large diameter, highly tapered, trumpet carrying either a flat (as Peter D suggested) or slightly domed (as per Bernard's first photo) mesh? Although, if I understand StanJ's point correctly, there will always some reduction in efficiency whenever mesh (or other filter medium???) is employed.
Stan, wot's WOT?
