wow. quite a list. still dont know about the rationality. i think i read about the 5/8"/' morse origin somewhere, but that also seems like an arbitrary choice. i didnt see any that were 90 degrees, which would seem like a logical first guess for aligning a length and a center. i wonder if there is any math out there on the ideal taper form, given its use in specifed materials and load conditions?
