Can anyone provide a technique or mathematical formula for determining the parallel convex and concave arcs of a fuselage band where there is a taper from one side to the other? It seems like there must be a formula based on the angle described by the axis and the tangent edge of the truncated cone matching the band, but I can't figure it out. I know I could just paint these bands, but there are circumstances where a decal would be much more convenient.
