Sleuth takes a true position.

It was 5 a.m. and Sleuth's phones were ringing incessantly--first his cell, then his landline, and then his cell ... ad nauseam. After about five minutes of this, he concluded that whoever-it-was was not going away.

The raspy voice at the other end of the line belonged to none other than Major Albert Payne of the Army's top-secret CGIU (Counter Gadgetry Intelligence Unit). "Sleuth," it said, "you got any plans today?"

"I did," said Sleuth.

"Well, cancel them and meet me over at Major Motor's Aerospace Division at 0700."

"Yes, Major Payne," said Sleuth meekly. "May I ask what this is about?"

"It's the GIZMO and now I've already said too much, so get your butt over here on the double."

The Gyroscopic Intermitting Zero Motion Oscillator, otherwise known as the GIZMO was so secret that Sleuth himself did not know anybody who even knew anybody who knew what it did or what it was for. He did know that the GIZMO had two intricate titanium components that had to mate perfectly in order for it to have any chance of working. The design of GIZMO was so sensitive that prototypes of these X and Y modules were being manufactured by two different companies and shipped to the Army's CGIU R&D lab for final assembly.

After arriving at Major Motors Aerospace, Sleuth was ushered into the metrology lab. A shiny X-mating GIZMO module was mounted on the CMM. It looked like a twisted Belgium waffle iron but with about a dozen bolt holes in it.

"There it is," said Major Payne. "MM Aerospace has already shipped us a hundred of these babies and they were perfect. But the Y-mating module is a different story. Parts 'R Us--a company you recommended for this no-bid contract, Sleuth, fell down on the job. They shipped us 100 parts and we had to send 15 of them back because they didn't pass our true position CMM inspection. We've got just a month to get 250 GIZMOs assembled for field trials and we need all the mating modules we can get our hands on.

Payne let Sleuth know that Major Motors Aerospace people were the good guys in this tragedy. Both companies received their drawings at the same time, and both were manufacturing their mating components on nearly identical equipment. In addition, the CGIU provided both manufacturers with the latest version of measurement programs that were used on comparable CMMs.

While Major Payne was heaping praise and blame on the two parties, Sleuth was watching the CMM as it went through its true position measurement...
