"Run-out must not exceed .003 in. If it is found necessary to regrind the
disc faces they can be ground up to a maximum of only .040 in off the
original thickness of .350 to .340 in. This may be ground off equally both
sides, or one more than the other, provided that the total does not exceed
.040 in. The reground surface must not exceed 63 micro-in. After grinding
the faces must run true to within a total clock reading of .002 in and the
thickness must be parallel to within .001 clock reading."
