My plans and instruction manual (60 photocopied text sheets) say to slip the ribs onto the spars, glue the reinforcement plates where diagramed, bolt up the wing fittings, tension the drag and anti drag wires, then “trammel” the bays of ribs before glueing.
The dictionary doesn’t offer an appropriate definition but I am guessing it means square plumb straight and fixed?
