Frequently Asked Questions

What are common issues found in older Remington 1900 shotguns?

Common problems include a broken forend latch that won't stay attached, 'off-face' barrels where there's a gap between the breech and receiver, and non-functional automatic ejectors due to broken springs. These issues often arise from heavy use over time.

How is a broken forend latch spring repaired on a Remington 1900?

A new spring is fabricated from 3/16" spring steel flat stock. The process involves layout with Dykem, drilling, sawing, hot-forging to shape, hardening by quenching in oil, and tempering in niter bluing salts at 600°F to achieve the correct spring temper.

What is the proper method for fixing 'off-face' barrels on a shotgun?

Professional methods include installing an oversized hinge pin, welding the barrel hook, or shimming the hook. This video demonstrates shimming using steel shim stock and retaining compound, followed by careful filing to ensure the barrels fit tightly against the receiver face.

How are automatic ejector springs repaired on a vintage shotgun?

The repair process for automatic ejector V-springs mirrors that of the forend latch. It involves fabricating a new spring from stock material, shaping it through hot-bending and filing, hardening it by oil quench, and tempering it in niter salts to restore its spring properties.
