Punches are indispensable, and half a dozen different sizes each of round (Fig. 13) and oval (Fig. 14) tools should be obtained. Round punches are made in sizes from No. 1, suitable only for very narrow straps, to No. 16, which make a hole ⅝ in. in diameter. Oval punches are numbered, according to size, from 17 to 32, and make a hole of similar dimensions to the round punches just mentioned. Punches of intermediate sizes, Nos. 3 to 13 or Nos. 19 to 29, will, however, answer for most repairing jobs. The ovals are preferable in most cases, as they make holes in the straps large enough for the purpose without impairing the strength so much as the round ones do. Buckle tongue punches, or crew punches (Fig. 15) are handy; these are made in three or four sizes, and they run from No. 33 to No. 43, and are used for making the holes that take the heel of the buckle tongue when the buckle is placed in its chape. This hole may also be made by punching two holes at a suitable distance from each other, and cutting between them, thus
. The strap has to be bent and a hole cut through the bent end, the piece between the holes for the tongue of the buckle being afterwards cut out. The punches shown by Figs. 16 to 18 may be used to cut saddle girth chapes, brace ends, etc.
