Since there can be variations in the mounting surface
of the bedbar, a new bedknife will not be perfectly flat af-
ter it is installed. Because of this, it is necessary to back-
lap or grind a new bedknife after installing it to the
bedbar. Follow the existing angle that was ground into
thebedknife andgrindonly enough to makesure thetop
surface is true.
