After installing bedknife to bedbar, grind bedknife.
Bedknife Grinding
Since there can be variations in the mounting surface of
the bedbar, a new bedknife will not be perfectly flat after
it is installed to the bedbar. Because of this, it is neces-
sary to grind a new bedknife after installing it to the bed-
bar. Follow the existing angle that was ground into the
bedknife and grind only enough to make sure the top
surface of the bedknife is true (Fig. 23).
