My new rocking chair design is coming along very nicely. But there have been some real challenges. At the moment, the front legs/arm supports are single pieces of wood that pierce the seat (which extends back to make the rear legs). This joint is my usual brand of crazy, but that’s not the problem. The front legs need to be glued in place to the seat before I can move on to attaching the rockers. But the front legs point in a different direction from the back legs. And the tenons on the ends of the legs point in different directions as well. So they don’t fit in the mortises in the rockers. And there’s not enough flex in the assembled parts to force everything into place (I tried).
Cue the Wood Stretcher. I laminated the rockers, so they are exceptionally strong. But they do flex a little, with very little risk of breaking. Flattening them out a bit by pulling down on the ends with clamps doesn’t just take some of the curve out; it effectively lengthens the rockers a little. Just enough, in fact, to allow me to slip the tenons into the mortises. Releasing the clamps lets the rockers spring back, and locks the joints together, making the attachment between the legs and the rocker pretty much impossible to get apart (without flattening the rocker again). It’s incredibly cool to see this work.
