The plurality of first notches may include a first vertical notch 22 and a first horizontal notch 24; it should be noted that the terms "vertical" and "horizontal" are used only to distinguish directions; the notches so labeled may be oriented side-by-side vertically up, down, or horizontally when using a punch centering block arrangement, each notch centered on an axis, the first vertical notch 22 centered on a first axis 26, the first horizontal notch 24 centered on a second axis 28, the first axis 26 transverse to the first workpiece engaging surface 16, the second axis 28 transverse to the first block engaging surface 18; "transverse" means any angle greater than 0 to 90 degrees. The exemplary first axis 26 is perpendicular to the first workpiece joining surface 16, and the exemplary second axis 28 is perpendicular to the first block joining surface 18. As described in more detail below, each of the plurality of first notches (first vertical notch 22, first horizontal notch 24) may be configured to form one radial half of the punch hole.

The second block 14 may be defined as a plurality of second reference surfaces and a plurality of second recesses. The plurality of second reference surfaces may include a second workpiece engagement surface 30 and a second block engagement surface 32, the exemplary second workpiece engagement surface 30 and second block engagement surface 32 being perpendicular to each other; the second workpiece engaging surface 30 may have a first predetermined level of flatness configured to lie flush against a second surface portion of the workpiece 20; the first and second surface portions of the workpiece 20 may be in the same plane or different planes; the second block engagement surface 32 may have a third level of flatness and thus may be configured to lie flush against the first block engagement surface 18 of the first block 12.

The punch centering block arrangement further includes a plurality of sleeves sized to fit the punch holes defined by the various blocks. Each of the plurality of sleeves has a different sized inner diameter to accommodate a different sized punch. Fig. 8 and 9 illustrate a first sleeve 86 having a first inner diameter 88; FIGS. 10 and 11 illustrate a second cannula 90 having a second inner diameter 92, the second inner diameter 92 being smaller than the first inner diameter 88; fig. 12 and 13 illustrate a third sleeve 94 having a third inner diameter 96, the third inner diameter 96 being smaller than the second inner diameter 92.
