Joinery Shootout

We push 18 popular frame joints to the breaking point

by

When designing a piece of furniture, how do you decide on the joinery? Chances are aesthetics, efficiency, and available tools factor into the decision. But so does strength. Fine Woodworking teamed up with a group of research engineers to test 18 popular frame joints and see which is strongest. We made five sets each of 18 different types of joints in cherry, a species used often by furniture makers. The samples were placed in a servo-hydraulic materials testing machine--essentially a hydraulic ram hooked up to a computer to record force and movement--and broken. Which ones were sturdiest? The results will surprise you.

Learn more about our testing in this short video.
