  • Wood Strength

    These parts are fairly slender, and weaker woods won't hold up. A good indior of a wood's strength is its density — the weight for a given volume. This is measured by its specific gravity — the weight of a volume of wood divided by the weight of the same volume of water. Generally, the higher the ratio, the denser and stronger the wood.
