We use trees as shelter, food, fuel, furniture, sports equipment, synthetic cloth, huge ultra-modern windmill propellers, patterns for metalwork, and a myriad of other uses.
nearly everything we touch and use has a tree source.
Probably the next development in joinery was the dovetail joint, which is often seen in box or drawer construction.
The joint is comprised of a wedge-sheped tenon (the "tail") on one component which overlaps a corresponding wedge-shaped slot in a second component.
Centuries-old wooden ships and buildings stand as a testament to the second life of the tree.
FUNDAMENTAL JOINERY There are really only a few ways to successfully join wood, whether building a house or a chair.
By understanding the basics of joinery, we can also understand and predict the utility and ultimate degradation of some furniture.
The greatest strength of wooden components is found parallel to the same direction as the original stem (imagine the stress of a tree blown by high winds).
That is why the long direction of boards runs in the same direction as in the tree.
WOOD AS A BUILDING MATERIAL Wood is a plant stem tissue, and the two most important functions are support and conduction.
The crown (leaves and branches) of the tree is supported by the stem, which must resist the force from the weight of the branches and leaves, as well as the loads imposed by wind, rain, and snow and ice.
