Anvil 013: Rust Bluing on the Cheap

Published on August 7, 2020
Duration: 54:10

This video demonstrates a cost-effective DIY rust bluing process on a 1916 Spanish Mauser carbine, aiming for an armory-level restoration. It covers detailed disassembly, metal preparation, DIY steaming and humidity box techniques, and final oiling. The project emphasizes preserving historical integrity while preventing further corrosion, with stock repairs also addressed.

Quick Summary

Rust bluing converts red rust (ferric oxide) to black oxide (ferro-ferric oxide) for a durable, armory-style finish. DIY setups using PVC pipes for steaming and wardrobe boxes for humidity accelerate the process. After rusting, carding with a wire wheel removes loose oxide, revealing the final matte black finish.

Frequently Asked Questions

What is the goal of rust bluing on a firearm?

The goal of rust bluing is to convert existing red rust (ferric oxide) on the firearm's metal parts into black oxide (ferro-ferric oxide). This process creates a functional, durable finish that replicates the original armory look rather than making the firearm appear brand new.

How can I create a DIY humidity box for rust bluing?

A simple DIY humidity box can be made using a large cardboard box (like a U-Haul wardrobe box), a vaporizer to create steam, and a small ceramic heater to maintain temperature above the dew point, ensuring uniform rusting.

What materials are needed for a DIY rust bluing steaming rig?

For a low-cost DIY steaming rig, you can use a white PVC pipe, a turkey fryer pot, and a gas burner. The firearm barrel is suspended within the steam generated to convert rust into magnetite.

What is 'carding' in the rust bluing process?

Carding is a crucial step after steaming and controlled rusting. It involves using a fine wire wheel or degreased steel wool to gently remove the loose, powdery black oxide. This reveals the underlying dark, uniform finish and prepares the surface for the next stage.
