Hi Chris,
The spiral curve is not parametrized by arc-length.
(I think it is parametrized by angle)
So you first need discretize and approximate the spiral, to get the arc-length parametrization.

Thanks for the fast and exhaustive answer!

I think you need to re-parameterize the spiral :

Curves|Join Curves
Curves|Discretize
Curves|Approximate Parameterization = Uniform

then the curve parameter will be uniform in length. (but from 0 to 1 - so the sketch need to be scaled somehow?)

EDIT: I see chrisG already got this - of course.

Looks like one, doesn't it?
Lets ask?

I have added a new tool : Flatten Face
It creates a parametric developed face from cylindrical and conical faces.
Only option is "InPlace" to put face on XY plane, or tangent to source face.

... it works with regular cones and cylinders.
Trying to generate an oblique cone/cylinder by pure placement of the top sketch001 => no result.
Only the cutting part should be oriented.

This type of loft (oblique) produces BSpline surfaces.
The tool only work on faces supported by a real mathematical cone or cylinder.
