Appendix 1
Inspecting the Revolving Turret for Wear of the Mechanical Detents
The photos below show the revolving turret from a BH2-5RE modular revolving nosepiece which has severely worn
mechanical detents, as a result of extensive use and a poor service history. The revolving turret is made of brass (a soft
metal), with a hard, corrosion/wear-resistant layer of dull, silver-colored plating on the exposed surface. When the hard
plating in the area of the mechanical detents begin to wear away, as a result of severe use without routine cleaning and
re-greasing of the detents, the underlying brass will then be exposed. This exposed brass will then wear very quickly
with continued usage, soon rendering the BH2-5RE
unusable. Figure 46
shows an example of a revolving turret with
severe wear. Exposed brass is visible in the areas of the mechanical detents.
Figure 47
shows a close-up of one of the
mechanical detents, where the wear can clearly be seen.
