M98 Austrian Gasser revolver timing: Anvil 123

Published on April 21, 2023
Duration: 33:19

This video details the process of timing and reducing friction in an Austrian Gasser revolver, likely an 1898 model made in 1918. The instructor, Mark Novak, demonstrates how to identify and address internal drag points, polish critical surfaces, and even carefully bend the trigger nose with heat to resolve interference issues with the trigger guard. The guide also covers clearing binding points in the grip and reassembling complex components like the loading gate spring.

Quick Summary

Gunsmithing an Austrian Gasser revolver involves addressing friction points like the hand, hammer, and trigger. Careful polishing, stoning, and controlled heat bending of the trigger nose can resolve binding issues with the trigger guard. Proper reassembly and checking for smooth operation are key to successful timing.

Frequently Asked Questions

What are the common friction points in an Austrian Gasser revolver that require attention during gunsmithing?

Common friction points include the hand mechanism, hammer interfaces, trigger return, and where the mainspring contacts the grip. Polishing these areas with stones and files is crucial for smooth operation and proper timing.

How can trigger interference with the trigger guard be fixed on an Austrian Gasser revolver?

If the trigger binds on the trigger guard, it can often be corrected by carefully applying controlled heat to the trigger nose and gently bending it forward to create adequate clearance, ensuring the heat does not affect critical tempered surfaces.

What is the purpose of the tab on the Austrian Gasser's loading gate?

The tab on the loading gate, when opened, rolls inward and pulls the double-action dog out of the way. This action allows the cylinder to be indexed freely without needing to cock the hammer.

How do you identify binding issues between the grip and frame on a Gasser revolver?

Inletting compound or a similar marking substance can be applied to all contact surfaces. After cycling the action, the compound will transfer to the binding points, revealing where wood needs to be relieved from the grip.

Why is it important to polish longitudinal scratches on firearm springs?

Longitudinal scratches on springs can act as stress risers, creating weaknesses that may lead to the spring snapping over time. Polishing these surfaces smooth, ideally along the long axis, helps prevent such failures.
