Joinery is what it's all about. Great joinery is great woodworking. And when we think of great joinery we always think of... dovetails. But there's more, and one of my favorites is the mitered half lap. It's not all that hard to make if your table saw blade is sharp and properly adjusted, and you keep your wits about you.
A while ago, Woodsmith posted a video on their website to accompany an article in Issue 167 that makes it look easy.
Mitered half laps is also one of the many table saw techniques covered in the ShopNotes book, Table Saw: Tough Cuts Made Easy. See more at WoodsmithStore.com.
