bracket lines up with the desired mark on scale (D) you

wish the boring bits to be above the table surface at the

completion of the boring operation. Then tighten lock

knob (A). A stop screw (E) is provided to stop the boring

head from lowering when bottom of stop bracket (B)

contacts stop screw (E). There is another stop (A) Fig. 51,

provided on the left side of the machine to insure an even

depth across the line of holes to be bored. Set the stop

on the left side of the machine after the stop on the right

touch the stop bracket at the same time that the bits

touch the table, and tighten the stop screw (E).
