Taps come in at least three sizes. Earlier S&Ss may have the smaller size diameter and tapping must be done very carefully. also some taps furnished with aggrafs may be too small for the aggraff in which case a larger tap must be obtained. Also the hole, though it goes all the way through the plate can be too small for the right size tap and should be drilled with the right size tap drill for that larger size tap. If the aggraffs are not broken, redressing the holes by ragging the hole with an old bicycle brake cable can produce as good a result as replacing the agraff.
