The Troubleshooter

摘要

I was surprised the other morning when a molder I have known for a few years showed up at my office. He came bearing gifts in the form of a grocery sack full of clear parts that appeared dirty-they hadlarge black streaks in the middle of the part.The molder wanted me to solve a problem that had baffled him for several weeks. He set the parts out on my drafting table, which was OK since I don't use it for drawing prints anymore-at least, not since they invented computers.
