Bayonet Repair and Restoration

Published on September 16, 2022
Duration: 15:14

This guide details the repair and restoration of bayonets, specifically focusing on M14 and Garand models. It covers techniques for removing seized screws using an 'easy out' after drilling, repairing damaged screw heads with TIG welding, cleaning and reassembling internal mechanisms, and applying a parkerizing finish. The process emphasizes preserving original components where possible and restoring functionality and appearance to neglected bayonets.

Quick Summary

Repairing seized bayonet screws involves drilling into the head, using an 'easy out' for extraction, and potentially welding filler rod to rebuild the head before cutting a new slot. Handles are cleaned with solvents and water, and blades can be restored with a parkerizing solution followed by oiling.

Frequently Asked Questions

How can I remove a seized screw from a bayonet?

To remove a seized bayonet screw, first drill a hole into the screw head. Then, insert an 'easy out' tool into the hole and carefully torque it to extract the screw. For heavily rusted screws, soaking the component in penetrating oil for several hours may be necessary before attempting removal.

What is the best way to repair a damaged bayonet screw head?

Damaged bayonet screw heads can be repaired by welding a piece of filler rod into the drilled hole where the screw was removed. Once the weld cools, grind the material down to the correct diameter and shape, then cut a new slot into the head for a screwdriver.

How do I clean and restore the handles of an old bayonet?

Bayonet handles, often made of phenolic or plastic, can be cleaned by scrubbing with a toothbrush and water or an industrial solvent to remove rust and grime. After cleaning, they should be dried thoroughly, ideally with compressed air, and then oiled.

What is the process for parkerizing a bayonet blade?

To parkerize a bayonet blade, first clean and boil the components. Then, dip the blade into a parkerizing solution, rinse it with water, and immediately oil it with used motor oil. This process helps restore the finish and protect against rust.
