Quick Summary

Proper polishing of firearm parts is crucial for achieving a fine finish, especially when preparing for plating such as gold or nickel plating. Using a flat bar stock as a backer when polishing flat surfaces like triggers ensures a consistently flat and smooth finish. For pitted areas, a file can serve as an effective backer for abrasive material. Screwheads can be polished efficiently by chucking them in an electric drill and using a wooden backer with abrasive material.

Frequently Asked Questions

What is the best way to polish a firearm trigger for plating?

To polish a firearm trigger for plating, place it flat on cloth-backed abrasive material. Use a piece of flat bar stock as a backer to ensure you achieve a flat, smooth surface, which is essential for good plating adhesion.

How can I polish pitted areas on gun parts like a trigger guard?

For pitted areas on gun parts, start by using a file to remove the majority of the pitting. Then, use the file itself as a backer for abrasive material to polish the area smooth, preparing it for plating.

What is the recommended method for polishing screwheads on firearms?

Screwheads can be polished effectively by chucking them into an electric drill. Polish them at a medium speed against abrasive material that is backed by a piece of wood for support and control.

Why is polishing important before plating gun parts?

Polishing is critical before plating gun parts because it creates a smooth, defect-free surface. This ensures that the plating adheres properly and results in a fine, aesthetically pleasing finish, preventing imperfections from showing through the plating.
