Fuller (metalworking)
Encyclopedia
In metalworking
, a fuller is a tool used to form metal when hot. The fuller has a rounded, either cylindrical or parabolic
, nose, and may either have a handle (an "upper fuller") or a shank (a "lower fuller"). The shank of the lower fuller allows the fuller to be inserted into the hardy hole of the anvil
. Upper fullers furthermore come in "straight" or "cross" varieties, depending on the orientation of the handle relative to the face.
The fuller is used mainly to spread the metal. The fuller is placed against the metal stock, and then either the fuller (for an upper fuller) or the stock (for a lower fuller) is struck with a hammer. The rounded nose of the fuller spreads the metal more efficiently than the flat face of the hammer. The process leaves ridges in the stock, which may then be flattened out later with the hammer or other tools.
Metalworking
Metalworking is the process of working with metals to create individual parts, assemblies, or large scale structures. The term covers a wide range of work from large ships and bridges to precise engine parts and delicate jewelry. It therefore includes a correspondingly wide range of skills,...

Anvil
An anvil is a basic tool, a block with a hard surface on which another object is struck. The inertia of the anvil allows the energy of the striking tool to be transferred to the work piece. In most cases the anvil is used as a forging tool...
