How to Repair a Micrometer Lock Ring

A micrometer is a device used for measuring short distances — and like almost any piece of equipment you use over a long period, it may degenerate and need repair. If there are reading errors or the ratchet stop doesn't work any longer, you may need an experienced micrometer repairman to fix it — or you may need to replace the tool. However, if the damage is minor, such as a lock ring that no longer functions, you may replace it yourself. Replacing the lock ring is the only option if it's no longer working.
