Method for forming planks for use in chord components of integral truss-supported decks comprises placing the squared off leading edge of a blank, unprocessed plank on a supporting frame; indexing the plank longitudinally and laterally in the frame accurately locating it for drilling; and drilling splice plate locating holes at each extremity of the plank, and side connector holes in a spaced relation along the sides of the plank, with the aid of drill jigs located above the frame.
