8.7.7 Knife Bar Gibs

The knife bar gibs are two plates on either side of the arch that guide and hold the knife as it cuts. If
adjusted too tight the knife may not come down, or the gibs and knife bar could be damaged due to
scoring. If too loose, you could get uneven or inaccurate cuts.
There are four socket setscrews with jam nuts on each side of the arch that adjust the gibs, (Figure
30). These should be adjusted only with the knife bar directly behind the bolts being tightened.
