Why Your Mitres Close at One End and Open at the Other

Why do your mitre joints close perfectly at one end, yet leave a frustrating gap at the other? In this video, we uncover the small measurement, cutting, and setup errors that create uneven mitres—even when the pieces appear perfectly straight. You’ll learn how blade runout, fence alignment, compound-angle mistakes, inconsistent stock thickness, tear-out, and tiny differences in length can turn a seemingly simple joint into a problem that never quite closes. We’ll also demonstrate practical ways to diagnose the real cause, including checking your saw and mitre gauge, testing with offcuts, correcting cumulative errors, supporting long workpieces, and making controlled adjustments without repeatedly shortening your project. You’ll discover why forcing a mitre closed often makes the joint worse, and how experienced woodworkers achieve clean, consistent corners. Whether you are making picture frames, trim, boxes, cabinets, or fine furniture, these techniques will help you produce mitres that meet cleanly from corner to corner.
