re: limb taper
the post linked below shows the width and thickness tapers of the "bow" I profiled in the spreadsheet and fitted the 1.2 x ellipse to.

RyanY:
Del, Certainly those polycarbonate bows are close. Close enough for a pyramid taper to be "practically" even in thickness taper. I do notice some irregularities in the shape. Looking at both photos, one limb appears stiffer in the outer limb as indicated by Hickman. The other appears weak almost mid limb with more space between the circle and the tiller at that point (not sure what's going on there). Could be asymmetries but the point was not if it was practical or not, just that it's not entirely true that a straight profile will result in a perfectly circular tiller in a bow limb.
Del the cat:
I think you can fit a better circle to the top one... ;) (I'll do it if you like)
But I'd like to see the corrected pyramid fitting better!

William M.:
The radius of the circle is half the length of the bow?
Digital Caveman:
No, the circle radius is unrelated, it changes based on how far the bow is drawn.
