This video details the process of relaying the rib on a vintage Remington Model 1900 side-by-side shotgun. Larry Potterfield demonstrates how to diagnose a loose rib using a rubber mallet and the 'ring test'. The repair involves carefully heating the barrels to melt old solder, removing the rib, thoroughly cleaning and preparing the metal surfaces, and then re-soldering the rib using 50/50 lead-tin solder and flux.

Quick Summary

To identify a loose shotgun rib, tap the barrels with a rubber mallet. A dull thud indicates looseness, while a clear ring signifies a secure rib. Repair involves heating the barrels to melt old solder, removing the rib, cleaning surfaces, and re-soldering.

Frequently Asked Questions

How can I tell if my shotgun's rib is loose?

Tap the shotgun barrels gently with a rubber mallet. A loose rib will produce a dull thudding sound, whereas a properly attached rib will ring clearly.

What is the best way to remove a shotgun rib for repair?

Heat the barrels with a propane torch to melt the old solder. As the solder softens, carefully insert small wooden wedges under the rib to lift it without causing damage.

What preparation is needed before soldering a shotgun rib?

Thoroughly clean the barrel and rib surfaces to remove all corrosion and old solder, ensuring you reach bare metal. Degrease the parts with acetone for optimal solder adhesion.

What type of solder is recommended for shotgun rib repair?

A 50/50 lead-tin solder is commonly used for shotgun rib repairs. Proper flux application is also essential to ensure the solder flows correctly and creates a strong bond.
