jyviko a30a85698f Thread: the chamfered tip reaches ISO 724's external minor diameter ...

ISO 4753's chamfered end bounds the end's diameter by the minor diameter. The default took the
modelled root (the basic d1) for it, so the cone's small circle lay on the root cylinder and
the chamfer ring pinched to nothing wherever the groove reached the end. The default is now
the external minor diameter d3 = d - 1.226869 P of ISO 724, below d1: the cone crosses the
root, each end is a whole disk of d3 inside a whole conical ring. ISO 4753 is for ISO metric
threads; the other forms, whose root is already their design minor, give chamfer_depth.

Ladder 06/017's analytic volume follows (1945.354522563); its golden entry re-measured.
