 Metal Finishing:
In the damaging of sheet metal, force has been exerted on the surface
of the part or panel. In the finishing repair of sheet metal
surfaces, force is used to repair dents and dings. The use of metal
repair equipment is to apply the necessary force to reverse the effect
caused by various means. By striking the sheet metal surface.
By sheet metal metal surfaces. By prying and levering forces applied to
the opposite side of finished metal surfaces. By grinding and
sanding with abrasive materials to provide a smooth finished surface.
Dent & Ding Equipment:
Basic metal finish repair equipment consists of:
- Body Files are used in the removal of surface metal during
the course of sheet metal repair. These files are available in
different shapes and cutting grades.
- Shrinking/Bumping Pick Hammers are used to flatten or
straighten sheet metal surfaces. There is a wide variety of
bumping hammers.
- Body Punches can be found in various lengths and sizes.
They are commonly used to reach dented areas in need of repair that are
not easily accessible.
- Body Hooks and Picks are used to remove or release dented
sheet metal in areas that are inaccessible by other means.
- Body Spoons are comprised of a flattened steel bar that has
been thinned on one end. The other end has been shaped as a
handle. Some handles are "L" shaped. Others are "S" shaped or
curved. These shapes are to be determined by their purpose or use.
- Grinders/Sanders Metal grinders and sanders all perform the
same task. They remove unwanted irregularities to produce a smooth
finished surface using an abrasive action. The degree of this
abrasive action can be achieved by the use of various grades of sanding
grits.
- Dolly Blocks are a solid steel block that has been sanded
smooth or slightly crowned on one side. When a severe ding (high
area) is found, a dolly block should be held firmly in the hand with its
striking surface placed against the opposite side of the sheet metal,
directly behind the ding. The outer surface ding can then be
hammered smooth. The dolly block serves as an anvil.
- Turn Buckles/Pullers Turn buckles and pullers are make from
steel cables or chains, clamps or hooks, and have a levering bar or
tightening screw with or without a locking action. Some are make
of a steel rod with a heavy steel handle that slides along the rod.
One end of this kind of puller can be attached to the center of a large
dented area, and the backward motion of the heavy steel handle acts to
pull out (release) the dent.
