Anvil 077: Volcanic Activity

Published on January 21, 2020
Duration: 22:57

This video details the assembly and maintenance of a Volcanic pistol, highlighting its unique toggle-link action and rocket ball ammunition. It explains the mechanics of the magazine loading system, the function of the locking mechanisms, and the importance of proper conservation to prevent rust. The presenter emphasizes the historical significance of the Volcanic as a precursor to modern repeating firearms and discusses the inherent weaknesses of its toggle-link design compared to later lever-action systems.

Quick Summary

The Volcanic pistol features a toggle-link mechanism, an early design for repeating firearms, and uses unique 'rocket ball' ammunition. While historically significant, its toggle action is prone to wear and slop, making it less robust than later lever-action designs. The ammunition's mechanical sealing was also a significant limitation.

Frequently Asked Questions

What is the primary mechanism of the Volcanic pistol?

The Volcanic pistol utilizes a toggle-link mechanism, which involves two-piece firing pins and links that collapse to open the action. This design was an early step towards repeating firearms and shares similarities with later lever-action rifles like the 1866 Winchester.

What type of ammunition did the Volcanic pistol use?

The Volcanic pistol fired a unique 'rocket ball' ammunition. This cartridge had a hollow base and contained an anvil, fulminate, a cork ring, and black powder. Its small size limited the powder charge, and its mechanical sealing was a significant drawback.

Why are Volcanic pistols and similar toggle-action firearms considered weak?

Toggle-action firearms are considered weak because their pins are loaded in sheer, not compression, leading to significant wear and slop over time. This design has many moving parts that can loosen, making them less robust for powerful cartridges or sustained firing compared to later designs.

How does the Volcanic pistol's magazine loading system work?

The Volcanic pistol's magazine is loaded by rotating a follower 90 degrees via a plunger in the nose cap. The magazine spring then pushes the follower up, and a retaining screw prevents it from ejecting when the gun is open. This system is similar to that found in the Henry rifle.
