These three tenor backs have just received their strip bracing over the center joint. The backs are book matched, thus they must be made in two pieces, carefully glued at the center. To insure the integrity of that joint I always glue a strip brace over the joint. I use pieces of maple veneer cut cross grain so that the grain of the wood crosses the center seam. This thin veneer has no strength beween the grain but it is tough as heck across the grain, Just what we need to strengthen that joint. It is also very light.
