Species: Pseudotsuga menziesii
Sources: Western USA, Canada, UK
Characteristics of the tree: A tall tree with a straight trunk, it grows to an average height of 200ft but can reach 300ft. Forest-grown trees produce trunks up to 6.5ft in daimeter and are free of branches for much of their height.
Characteristics of the wood: A straight-grained reddish-brown timber, with distinctive earlywood and katewood grain. Obtainable in large knot-free sizes.
Workability: Works well with hand and machine tools, but can dull cutting edges. Can be brought to a smooth finish, but the harder latewood grain can be left proud of the surface after sanding.
Average dried weight: 33lb per cubic ft
Finishing: Stains relatively well, although latewood is more resistant. It can be satisfactorily painted or varnished.
Common uses: Joinery, plywood. Widely used for building construction.
