EP{G. Eric Platford - Chief Quality Engineer}10/M.1.21. We have introduced new methods of machining and inspection, and I am pleased to state that we are able to produce tappets to within .002 out of truth, so the Test Dept. may rest assured that they will get no more engines on test unless the tappets are within these limits.
