John,
Bell shaped revolved surface
Line swept along helix of desired pitch so that resultant helical ribbon surface intersects bell surface.
Curve of intersection between bell and ribbon.... ta-da

I am looking for a solution to create a helical sweep path that varies in > pitch.

I took your challenge.
· create bell profile · create desired helix at center of spline · create sketch with line from end of helix to center of bell · revolve surface of the bell · surface sweep of the line sketch around the helix · 3d sketch/intersection curve select your 2 surfaces and VOILA!! a spline wrapped tightly around a bell at a specified helical angle.Corey Scheich
how about doing some maths in excel and importing to a curve through free points solution?
first I thought about our SolidSketch add-in, which can wrap any sketch around any surface
