Frequently Asked Questions

How can you tell if a shotgun rib is loose?

You can determine if a shotgun rib is loose by tapping the barrels with a rubber mallet. A properly attached rib will produce a clear, ringing sound, while a loose rib will emit a dull thud, indicating a failed solder joint.

What materials are needed to resolder a shotgun rib?

Resoldering a shotgun rib requires a propane torch, flux, 50/50 lead-tin solder, cleaning supplies like acetone and Simple Green, and tools for clamping and shaping such as spring clamps, wire, chisels, and specialized files.

What does the 'KED' designation mean on a Remington Model 1900 shotgun?

The 'KED' designation on a Remington Model 1900 shotgun stands for K-Grade, Ejectors, and Damascus barrels, signifying a higher-quality model with specific features manufactured around 1904.

Why is surface preparation important before soldering a shotgun rib?

Thorough cleaning and degreasing of the barrel and rib surfaces with agents like acetone are crucial before soldering. This removes oils, corrosion, and old solder, ensuring a clean metal-to-metal contact for a strong, reliable solder bond.
