Slotting Square Hole in Extension Wrench
In this operation the piece of work is too long to be set in a vertical position; it is, therefore, passed through the spiral head spindle and is clamped in the chuck. The slotting attachment head is then set so that the tool moves in a path parallel to the top of the table.
The ability to swing the head from a vertical to a horizontal position is one of the features of the B. & S. attachment.
The piece of work is indexed by means of the rapid index plate. All necessary movements of the table are made by hand.
