Colt 1911 Grip Checkering: Anvil 031

Published on July 29, 2022
Duration: 40:18

This guide details the process of preparing custom 1911 grip scales for checkering. It covers removing existing grips, understanding grip screw and bushing specifications, creating a jig for thin grips, and the meticulous process of pilot drilling and hand-tightening grip screws. The video emphasizes careful preparation before the actual checkering begins, highlighting the importance of avoiding damage to expensive custom grips.

Quick Summary

When installing 1911 grip screws, avoid over-torquing by hand-tightening only until snug. A light molybdenum coating is recommended, and power tools should never be used to prevent stripping threads or splitting wood grips. Grip bushings are essential for durability, providing robust threads for the screws.

Frequently Asked Questions

What are the typical dimensions for 1911 grip screws and bushings?

1911 grip screws are generally 0.150 inches in diameter with 50 threads per inch. The bushings they thread into are typically found in a 0.235-inch by 60 hole and are designed to provide adequate thread depth and prevent stripping in the frame.

What is the correct way to install 1911 grip screws?

It's crucial to avoid over-torquing 1911 grip screws, especially in wood grips, as this can strip the threads or split the material. Use a very light coating of molybdenum on the screws and hand-tighten them until snug, not forced. Never use power tools for installation.

Why are grip bushings used on 1911 pistols?

Grip bushings are used on 1911 pistols to provide a more durable and reliable thread for the grip screws. They are particularly important for high thread counts like 50 TPI, preventing the frame material from stripping out over time with repeated installation and removal.

How do you prepare thin custom wood grips for checkering?

For thin custom wood grips, you often need to create a temporary jig from a piece of wood. This jig provides a stable surface to hold the grip and allows the checkering tool to be worked at an angle and underneath the grip without interference, preventing damage to the delicate material.
