After correcting ring and cylinder, the type face may
be raised to the writing line by peening or lowered by
using the S-6 bar bender high on the type bar (Figure 8).

Bar Adjustment
Another method of raising or lowering end type bar
faces involves the use of two type aligning wrenches
(Figure 16). A left-hand bar is illustrated but a right-
hand bar will respond to the same treatment in reverse.
This procedure requires forming the type bar just a little
at a time and must be checked after each forming to in-
sure that the type bar enters the guide properly.

Bindin~
in Guide
If the type bar has a tendency to bind in the guide,
(Figure 17), it indicates that the type bar has be<,;n
formed too far. Some of such a bind may be relieved by
a slight twist while observing the bar as in Figure 15.
TYPE SOLDERING FIXTURE
may be attached to the type
bar to facilitate resoldering a type slug which may be
too far out of alignment for the aligning tools (Figure IS).
When a type face requires raising or lowering by .025"
or more it will generally prove profitable to use the fixture.
