How to Re-Blue a Gun: A Comprehensive Guide
When it comes to maintaining and restoring old guns, one of the most crucial processes is re-blueing. Re-blueing is a process that helps to rebuild and restore the original protective layer of blueing or patina on the firearm, which is essential to protect the metal from rust and corrosion. In this article, we will cover the step-by-step guide on how to re-blue a gun.
Understanding the Importance of Re-blueing
Re-blueing is a necessary process when dealing with antique or restored firearms. Over time, the original blueing layer can wear off, leaving the metal vulnerable to corrosion and rust. This is particularly true for firearms exposed to moisture, salt, and other environmental factors. A restored blueing layer ensures that the gun remains not only aesthetically appealing but also durable and functionally reliable.
Basic Materials and Equipment Needed
Before starting the re-blueing process, you’ll need the following materials:
- Gun cleaning cloths
- De-waxer or lubricant
- Wax or metal conditioner
- Steel wool
- Rubber pads or cloth
- Trichloroethane or commercial blueing solution
- Thermometer
The Re-blueing Process: A Step-by-Step Guide
The re-blueing process is divided into several stages:
Removing Old Blueing and Solvent Wipe-Downs
- Removes old blueing:
- Use steel wool to scratch off any old blueing residue from the gun barrel.
- Wipe away any debris with gun cleaning cloths.
- De-waxes or lubricates:
- Apply a light coat of de-waxer or lubricant to the barrel surface to prevent re-blueing from adhering to oils or waxes.
- Thermometry check:
- Ensure the temperature is at room temperature (68°F – 72°F or 20°C – 22°C) before proceeding. High temperatures can affect re-blueing quality.
Wax and Metal Treatment
- Apply wax or conditioner:
- Lightly apply wax or metal conditioner to the barrel surface using gun cleaning cloths. This step helps promote adhesion of the blueing layer.
- Allow the wax or conditioner to set:
- Allow the wax or conditioner to sit for at least 30 minutes to help the metal particles bond together.
Trichloroethane or Blueing Solution
- Apply trichloroethane or commercial blueing solution:
- Trichloroethane: Dampen a cleaning cloth with trichloroethane and lightly apply it to the gun barrel. Work in circular motions to cover the area.
- Commercial blueing solution: Follow the manufacturer’s instructions and guidelines for application.
- Blueing reactions:
- After application, you may observe a color change or patina formation indicating the blueing process starting. This process can take 30 minutes to an hour depending on ambient conditions.
Final Rinse and Inspect the Result
- Rinse with cloth or brush:
- Use gun cleaning cloths or soft-bristled brushes to wipe away excess blueing solution and solvent.
- Inspect the gun:
- Assess the re-blueing progress, ensuring a uniform appearance. If needed, make additional applications to achieve optimal results.
Tips, Tricks, and Precautions
• Ventilation: Always work in a well-ventilated area when using trichloroethane or commercial blueing solution, as they can release irritating fumes.
• Gloves and face protection: Wear latex gloves and eye protection when working with trichloroethane or commercial blueing solutions to prevent skin and eye irritation.
• Preventing over-bluing:
- Monitor application levels to avoid over- blueing, which can lead to excessive buildup, damage, or discoloration.
• Using alternatives: - For those unable to secure trichloroethane or commercial blueing solutions, alternative methods and products may be used, although the results may vary. Consult with local gun shops, gunsmiths, or online resources for suitable alternatives.
Conclusion
Re-blueing a gun requires patience, attention to detail, and the correct materials. By following these steps and adhering to the guidelines, you will be able to restore and protect your firearm’s aesthetic and functional integrity. If you’re new to this process, consider consulting experienced gunsmiths or restoring experts for additional guidance or hands-on instruction. Remember to prioritize safety measures when handling chemicals, and always prioritize the structural integrity of your firearm throughout the re-blueing process.
