Dowel
A solid cylindrical rod of wood used as a fastener, alignment pin, or structural connector in woodworking joints, available in standard diameters from 1/4 inch to 1 inch.
In-Depth Explanation
Dowel joinery is one of the most accessible methods for creating strong wood-to-wood connections without visible mechanical fasteners. Pre-made dowel pins, typically fluted or spiral-grooved to allow glue distribution and air escape, are inserted into precisely aligned holes drilled in both mating pieces. A doweling jig is the essential tool for ensuring accurate hole alignment, as even slight misalignment can prevent the joint from closing. Dowel joints are commonly used in face frames, cabinet assembly, edge-gluing panels, and furniture construction. Hardwood species like birch, maple, and oak are preferred for dowels due to strength and straight grain.
Usage Example
I drilled matching 3/8-inch holes using a doweling jig and glued fluted birch dowel pins to join the two cherry boards into a tabletop panel.
