But how DO you curve a timber…exactly? One way is with ingenuity and brute force! The timber framers have a curve jig that they use to get just the right bend after slicing a timber, lining up major pieces of the grain, and gluing it back together. From a distance the piece will look solid with the grain matching. Though this is just one way to work with curves in timber framing, it’s a fun one to observe in process.
