  1. There will be several sets of numbers representing different log lengths. The stick is held up to the end of the log (running across the log measuring the diameter) with one end of the stick at the edge of the bark and wood. Where the bark and wood cross the other end of the stick, the appropriate number scale is read to determine the footage.

    Knowing as much as you can about the source of the wood—even the smallest details—can be helpful. If the wood came from a wood pile or a lumber mill where all the pieces were from trees processed locally, then the potential species are immediately limited. If the wood came from a builder of antique furniture, or a boat-builder, or a trim carpenter:...

    As with the wood’s source, its age will also help in identification purposes. Not only will it help to determine if the wood should have developed a natural patina, but it will also suggest certain species which were more prevalent at different times in history. For instance, many acoustic guitars made before the 1990s have featured Brazilian rosew...

    Some species of trees are typically very small—some are even considered shrubs—while others get quite large. For instance, if you see a large panel or section of wood that’s entirely black, chances are it’s either painted, dyed, or stained: Gaboon ebonyand related species are typically very small and very expensive.

    Simply knowing what the wood was intended for—when considered in conjunction with where it came from and how old it is—can give you many clues to help identify it. In some applications, certain wood species are used much more frequently than others, so that you can make an educated guess as to the species of the wood based upon the application wher...

    Believe it or not, freshly machined wood can have a very identifiable scent. When your eyes and hands can’t quite get a definitive answer, sometimes your nose can. Assuming there is no stain, finish, or preservative on or in the wood, quickly sand, saw, or otherwise machine a section of the wood in question, and take a whiff of the aroma. Although ...

    While certain woods can appear basically identical to one another under normal lighting conditions, when exposed to certain wavelengths—such as those found in blacklights—the wood will absorb and emit light in a different (visible) wavelength. This phenomenon is known as fluorescence, and certain woods can be distinguished by the presence or absenc...

    There are only a small number of chemical tests regularly used on wood, most of which are very specialized and were developed to help distinguish easily confused species with one another. They work by detecting differences in the composition of heartwood extractives. A chemical substance (called a reagent) is usually dissolved in water and applied ...

    Sometimes a wood species will have heartwood extractives that will be readily leachable in water and capable of conspicuously tinting a solution of water a specific color. For instance, the heartwood extractives contained in osage orange (Maclura pomifera)contain a yellowish-brown dye that is soluble in water. (This can sometimes be observed anecdo...

  2. The following formula may be used to determine the number of standard cords in a stack of wood: Number of standard cords =. [length (feet) x width (feet) x height (feet)] 128. Example. Take a stack of wood that is 10 feet long, 6 feet wide and 3 feet high. Substituting these figures into the formula we get:

I have spent a lifetime studying trees and logs, but I do not have any experience with wood from California.

  4. In this step-by-step guide, we will show you some tips and tricks to identify different types of wood species with relative ease. Step 1: Examine the Wood’s Color and Grain. The first step in identifying a wood species is to look closely at its color and grain pattern. Many types of trees have distinctive coloration or patterns that make them ...

  6. Apr 13, 2022 · Well, the kind that you’ll need to look at is a wood’s end grain. In order to identify wood by grain you’ll need to get your hands on a sample, so saw a bit off and sand it down with progressively finer sandpaper. Next, use a magnifier (any unit that provides between eight to 15 times magnification).
