Related to this torque topic is interuser variation in what is normal. It is important to try not to have an touch, because although it works perfectly well for intrauser consistency, it interferes with interuser consistency. Some people use a rather heavy touch as a matter of habit, and this is fine in that they can get highly accurate readings as long as they calibrate their micrometer accordingly. The problem arises when they use someone else's micrometer, or when someone uses theirs. The heavy-touch user gets false-small readings, and the normal-touch user gets false-big readings. This may not arise in one-person shops, but teams of workers sharing company-owned instruments must be capable of interpersonal consistency to do close-tolerance work successfully. There is a good and easy way to synchronize on this topic: it is simply to get used to the "feel" of how much torque it takes to slip the typical friction sleeve or click the typical ratchet thimble—and then incorporate that same feel into every use of a micrometer, even those that have no sleeve or ratchet. This is proper training for the machining trade, although it is not uncommon to encounter coworkers who were not well trained on this point. In many cases it seems that in drilling the "don't overtorque" idea into trainees' heads, an opposite extreme is mistakenly taught, where the user thinks the goal is to compete with everyone else on who can generate the lightest touch. Individuals naturally differ in their touch, so such a competition is not as effective at generating interuser consistency as is "imagining that every thimble has a sleeve to slip."
