7. Look at the endgrain.
Perhaps no other technique for accurate identification of wood is as helpful and conclusive as the magnified examination of the endgrain. Frequently, it brings the identification process from a mostly intuitive, unscientific process into a predictable, repeatable, and reliable procedure.
Looking at the endgrain with a magnifier shouldn’t be a mystifying or esoteric art. In many cases, it’s nearly as simple as examining small newsprint under a magnifying glass. There are three components necessary to reap the full benefits contained in the endgrain:
1. A prepared surface. When working with wood in most capacities, it becomes quickly apparent that endgrain surfaces are not nearly as cooperative or as easily worked as face grain surfaces. However, in this case,
it is absolutely critical that a clear and refined endgrain surface is obtained.
For a quick glance of a softwood sample, a very sharp knife or razor blade can be used to take a fresh slice from the endgrain. However, in many denser species, especially in tropical hardwoods, one of the best ways to obtain a clear endgrain view is through diligent sanding. It’s usually best to begin with a relatively smooth saw cut (as from a fine-toothed miter saw blade) and proceed through the grits, starting at around 100, and working up to at least 220 or 320 grit, preferably higher for the cleanest view.
