A stacking arrangement for wellhead tubular members wherein the adjoining ends of the tubular members are specially shaped to prevent or limit outward radial deflection and the damage associated therewith. The scale of the viewer representation of the window of interest may be substantially continuously varied so as to best account for the particular size of the available display area at the viewing machine. The punch apparatus can open precisely almost straight very fine through-holes of a diameter of 100 \u03bcm or less even in a sheet of thin, soft and deformable material. The method selects among the family one of the talar stem components having a desired physical characteristic based upon the analysis.
