Cabinet base (1)...

We have decided to go ahead with a cabinet base of the European beech. The process of creating a base from the beech slab involves a few steps. Initially the slab is partitioned for optimum use and minimal waste with an important consideration to grain orientation. Ideally, the slab is quarter-sawn. This particular slab is a cross between rift-sawn and quarter-sawn but I do need to pay attention to how the grain is oriented on the individual pieces. Ideally, the grain should be straight along the length of the aprons and all faces of the legs. The grain pattern in this case is diagonal to each face and not parallel to any of the four faces of the individual legs. I will saw the four leg blanks from the larger pieces I have already sawn with this in mind, and the possibility of re-orienting the leg blank within the larger piece of beech.

The original beech slab has now been sawn into three parts. Two of the three parts comprise the legs and the remaining part is utilized for the aprons. There are a total of four aprons, front, back, two sides. I'm cutting this slab in three stages leaving the sawn pieces to stabilize and to release any internal tensions. Since the original slab is resawn into smaller pieces, internal tension in the slab is released when resawing occurs. This isn't a hard and fast rule but in my experience occurs every time. I have also sawn the pieces oversized to allow for sawing at the next stage and the possibility of any cupping or bowing from internal stress. I leave these three sawn components to stabilize for a day or so before proceeding to the next stage of rough cutting the actual pieces which comprise the cabinet base.

Well for me its better to be more realistic.
