A reader asked me to comment on a situation he faced regarding calibration frequency for some gages he had on loan from his customer. The gages are only used once a year for this specific customer and—I’m guessing—spend about 80% or more of the year doing nothing.
External thread inspection can seem confusing and, in some cases, frustrating. There is a wide variety of inspection tools available for external threads.
Let’s see a show of hands. Does everyone here know what modular tooling/fixturing is by now? If yes, are you an advocate yet? If no, why not? Still think it’s not good enough? Just Tinker Toy, Erector Set or Legos? Well, think again.
A reader emailed me after reading some of my rants on thread ring gages dealing with the problems that come up in their use and calibration. But he added another dimension to the problem since he is in the calibration business: How do the Europeans deal with their solid thread ring gages?
