Stiffer buckles can be removed by laying the face of a
broad spoon against the ridge or valley and striking the
spoon with a hammer. The face of the spoon spreads the
force of the hammer blow. This application is commonly
known as ''Spring Hammering,'' because no backing up
tool is used.

A body jack will supply the required pressure in the event
the buckle is of a major nature and too stiff to be handled
in the manner previously mentioned. A jack exerts pres-
sure in both directions so the body must be protected
against damage from the base of the jack. The conven-
tional base furnished with jack equipment is sufficient for
low pressure application. When the buckle is very stiff, it
is general practice to use wood blocks. under the base as
an added precaution, Figure 62.
FIGURE 63
The tool face pushing against the damage should be broad
enough to spread the pre s sure through the entire buckle
rather than just against the immediate area above the
working face, Figure 63.
FIGURE 64
For pressing out a broad flat surface, a length of wide
plank or board used with the body jack is found satisfac-
tory, Figure 64.
FIGURE 65
The rubber head attachment for body jacks is used to
spread pressures over irregular surfaces. Rubber heads
must not be used to hold pressures against areas that are
to be heated, Figure 65.

Body spoon attachments for jacks are used against
high crowned surfaces and to reach behind inner body
construction, Figure 66.
