A dovetail joint is a joinery technique used in woodworking, traditionally used to joint wooden furniture. Dovetail joints are known for their inherent strength and resistance to being pulled apart (tensile strength).
What are the advantages and disadvantages of a dovetail joint?
The interlocking dovetail joint has a large gluing area, further adding to its strength. Hand cut dovetail joints require precise handsaw and chisel skills, and can be fiddly to mark out and cut. If dovetail joints are poorly made they will lose the advantage of strength and durability.
What is dovetail halving joint used for?
