This video demonstrates the process of repairing a loose top rib on a side-by-side shotgun, a common issue with older firearms. It covers identifying the loose rib using an auditory test, carefully lifting the rib by melting the old solder with a torch, thorough cleaning and preparation of the surfaces, and re-soldering the rib using 50/50 solder and improvised clamping methods. The finishing steps involve removing excess solder and cleaning the joint precisely.

Quick Summary

To repair a loose shotgun rib, first identify it using a 'tap test' with a brass hammer. Then, heat the area with a propane torch to melt the old solder, lift the rib, and thoroughly clean the surfaces. Finally, clamp the rib tightly and re-solder using 50/50 lead/tin solder and flux.

Frequently Asked Questions

How can I tell if the rib on my shotgun is loose?

You can perform a 'tap test.' Gently tap the barrels of your shotgun with a brass hammer. Listen for a change in sound; a dull thud or a different pitch compared to solid areas indicates a loose rib where the solder joint has failed.

What materials are needed to re-solder a shotgun rib?

You'll need a heat source like a propane torch, flux to prevent oxidation, 50/50 lead/tin solder, and materials for clamping the rib securely, such as soft iron wire and common nails.

What is the purpose of flux in soldering a shotgun rib?

Flux acts as a chemical cleaner during the soldering process. It removes any remaining oxides from the metal surfaces and prevents new ones from forming as you heat the joint, ensuring the solder flows properly and creates a strong bond.

How do you clean the area under a loose shotgun rib?

After heating and lifting the rib, clean the area thoroughly. Scrape out old solder, flux, and rust using a piece of hacksaw blade, then sand the surfaces to bare metal and clean with a degreaser.
