About This Tool
The Bevel Angle Calculator is a critical tool for ensuring tight, fair joints in boat construction. When two panels or planks meet at an angle (like the side of the hull meeting the bottom), their edges must be beveled to fit together perfectly. This calculator determines the precise angle for that bevel based on the angle of the hull joint. It also provides the 'Saw Setting Angle', which is the practical angle you need to set on your table saw or circular saw to achieve the cut.

Key Concepts:

Bevel Angle: The angle cut into the edge of a material to allow a tight joint with another piece.
Hull Angle: The angle between two joining surfaces, like the hull side and bottom.
Saw Setting Angle: The angle to set on your saw, measured from a square 90-degree cut.
Fair Joint: A joint that is smooth and aligns perfectly with the surrounding surfaces.
