Hi Tim @beetle ,
What I would do, is to make separate Objects for the different pieces of wood (ie: the same Material, but with different Coordinates, because they all use their own Object Coordinates).
You can also assign different Materials to the different pieces and just use a Vector Mapping Node to change (Location and Rotation) the Texture Coordinates.
You can also go a step further and make 3-Dimensional masks with a bunch of Math Nodes to differentiate between the pieces.
