Frequently Asked Questions

What are the key internal parts of an LC Smith sidelock action?

The LC Smith sidelock action is known for its simplicity, primarily consisting of four major internal parts: the hammer, sear, mainspring, and bridle. High-grade models often feature these parts polished and jeweled for enhanced aesthetics.

How is jeweling performed on LC Smith shotgun locks?

Jeweling, or engine turning, is achieved using an abrasive rod in a milling machine. The process involves creating overlapping, swirling patterns on components like the lock plate and bridle for a decorative finish.

What metal finishing techniques are used to upgrade LC Smith locks?

This upgrade involves advanced techniques such as polishing internal parts to a mirror finish, jeweling for decorative patterns, copper and gold electroplating on components like the hammer and sear, and niter bluing for springs and screws.

What is the purpose of copper plating before gold plating hammer and sear components?

Copper plating serves as an intermediate layer that provides a better adhesive surface for the subsequent gold plating. This ensures a more durable and uniform gold finish on the hammer and sear.
