A rivet gun, also known as a rivet hammer or a pneumatic hammer, [1] is a type of tool used to drive rivets. The rivet gun is used on rivet's factory head (the head present before riveting takes place), and a bucking bar is used to support the tail of the rivet. The energy from the hammer in the rivet gun drives the work and the rivet against ...
The rivet assembly is inserted into a hole drilled through the parts to be joined and a specially designed tool is used to draw the mandrel through the rivet. The compression force between the head of the mandrel and the tool expands the diameter of the tube throughout its length, locking the sheets being fastened if the hole was the correct size.
The downward force required to deform the rivet with an automatic riveting machine is created by a motor and flywheel combination, pneumatic cylinder, or hydraulic cylinder. Manual feed riveting machines usually have a mechanical lever to deliver the setting force from a foot pedal or hand lever.
The other new device, hitting at twice or three times the speed of the rivet gun, was the stone carver's hammer – a great blessing for smooth and rapid dressing of granite and marble. In 1930 F.J. Hauschild adapted the original stone carver's hammer into a portable hand-held steel tube frame for the purpose of straightening auto bodies.

Conservation-restoration work on historic firearms is a series of procedures designed to stabilize, repair or restore parts, and stop deterioration. [1] Stabilizing a firearm means establishing the ideal environment conditions, removing corrosion, replacing missing components, and repairing broken parts.
Whilst the basic principle can be traced back to other self-ejecting rifles, such as the single-shot Harrington & Richardson Model 755 rifle, this action has since been popularized in the United Kingdom by Southern Gun Company, who manufacture with "Manually Actuated Release System" (MARS) action rifles/pistol-caliber carbines in .223, .308 ...
