ADJUSTING THE CHISEL PARALLEL TO THE WORKPIECE
You can adjust the chisel (A) Fig. 24 parallel to the workpiece by loosening the screw (B) and rotating the chisel until the back surface of the chisel is touching the workpiece. Tighten the screw (B).
ADJUSTING THE SLIDING FIT BETWEEN THE HEAD AND THE COLUMN
A dovetail gib (A) Fig. 25 ensures a good sliding fit between the head and the column. Make the adjustment by loosening the two screws (B) and turning the adjusting screws (C). Tighten the two screws (B).
NOTE: The adjustment is correct when no side movement between the gib and the column is evident. Adjust the gib so that is is not so tight as to restrict the sliding movement or so loose that it affects accuracy.
