Published on October 22, 2021
Duration: 24:10

This video details the process of repairing a chipped wooden stock on a Fabarm Elos over/under shotgun, which experienced failure after approximately 35,000 rounds. The instructor emphasizes structural repair over cosmetic fixes, demonstrating how to inlet a new piece of wood, shape it to match the original contour, and ensure proper recoil transfer points. The process involves careful shaping with various tools and attention to detail to achieve a durable and aesthetically pleasing repair.

Quick Summary

Repairing a chipped firearm stock requires more than just cosmetic fixes; it demands structural reinforcement. The process involves carefully inletting a new piece of wood, matching its grain, and meticulously shaping it to blend seamlessly with the original contour. Ensuring proper recoil transfer points and avoiding stress on the repaired area are crucial for a durable, long-lasting fix.

Frequently Asked Questions

How can a chipped firearm stock be repaired?

Repairing a chipped firearm stock involves carefully removing damaged wood, cutting an oversized replacement piece with matching grain, adhering it securely, and then meticulously shaping it to match the original contour using saws, rasps, files, and sandpaper. The goal is to achieve a tight, structurally sound fit that doesn't interfere with the firearm's function.

What is the primary recoil surface on an over/under shotgun stock?

On an over/under shotgun, the primary recoil surface should be located at the rear of the stock, where it contacts the shooter's shoulder. The 'wings' that cover the action sides are primarily for cosmetic purposes and minor protection, not for transferring significant recoil.

Why is it important to avoid cosmetic-only repairs on firearm stocks?

Cosmetic-only repairs on firearm stocks are insufficient because they don't address the underlying structural issues that caused the damage. A proper repair must be structural to prevent the stock from failing again, especially under the stress of recoil during shooting.

What tools are essential for shaping a repaired firearm stock?

Essential tools for shaping a repaired firearm stock include a bandsaw for initial rough cuts, rasps (like Japanese Shinto rasps) for aggressive shaping, files for finer adjustments, chisels for precise material removal, and various grits of sandpaper for smoothing. Sharp tools are critical for control and preventing damage.
