8.7.2 Backgauge Gibs

If you are having trouble keeping the backgauge square, check for backgauge side play. Position the
backgauge approximately 2" (50-55mm) from the rear of the table and turn off power.
Remove the rear table cover. From the back, hold each end of the backgauge and try pulling one
end while pushing the other to rock it side to side (Figure 24. If there is noticeable side-to-side play in
the backgauge, the gibs will need adjusting. Check for play at various positions on the table.
NOTE: There will be some front to rear movement between the backgauge nut and screw.
The backgauge has two gibs that ride on a iron rail underneath the table, (Figure 25). These are
adjusted with setscrews that are held in position with jam nuts.
