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 nosepiece assembly

unusable. Figure 43

shows an example of a revolving

turret with severe wear. Exposed brass is visible in the areas of the mechanical detents.

Figure 44

shows a close-up of

one of the mechanical detents, where the wear can clearly be seen.
