FAQ
Frequently Asked Questions
A basic mitre joint is not inherently very strong because it relies on end-grain to end-grain gluing, which is weak. It is often reinforced with splines, biscuits, dowels, or nails for structural projects.
Common tools include a mitre saw (chop saw), mitre box with a backsaw, table saw with a mitre gauge, or a precision hand plane. A mitre square or protractor is used for marking the angle.
A bevel is an angled cut on the edge of a single piece of material. A mitre joint is created when two pieces, each with a bevel (typically 45°), are joined to form a corner. All mitre joints involve bevelled cuts, but not all bevelled cuts result in a mitre joint.
Yes. While most common for 90° corners (requiring two 45° cuts), mitre joints can be made for any angle. The formula is that each piece is cut at half the desired corner angle. For a 120° corner, each piece would be cut at 60°.
