Dovetail Basics
A dovetail joint is made up of a series of pins cut to extend from the end of one board interlocking with a series of tails cut into the end of another board. It is highly regarded for its resistance to being pulled apart (tensile strength) which is why it is commonly used to join the sides of a drawer to the front, and its attractiveness, allowing a feature to be made of the joint itself with an infinite number of variations.
