Frequently Asked Questions

What are the common issues found in older, heavily used double-barrel shotguns like the Remington Model 1900?

Common problems include broken forend latches, barrels being 'off-face' (not tightly seated against the receiver), and non-functional automatic ejectors due to broken springs, all stemming from extensive use over time.

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

The repair involves fabricating a new spring from 3/16" spring steel flat stock. This includes shaping it using layout fluid, drilling, sawing, hot-forging, hardening in oil, and tempering in niter bluing salts to achieve the correct spring temper and blue finish.

What does 'off-face' mean for a double-barrel shotgun, and how is it fixed?

'Off-face' means there's a gap between the barrel breech and the receiver face. Professional fixes include installing an oversized hinge pin, welding the hook, or shimming the hook, as demonstrated using steel shim stock and Loctite 680.

What is the purpose of tempering steel in niter bluing salts during gunsmithing?

Tempering in niter bluing salts, heated to around 600°F, prevents hardened steel parts, like fabricated springs, from becoming too brittle. It achieves a specific blue color, indicating the correct temper for durability and flexibility.
