SAFETY TIPS
• Measurements of wood moisture level are skewed by two
variables: ambient humidity and the density of the wood
species. The best way to compensate for the effect of these
variables is to develop your own moisture level curves,
based on your experience working with different species of
wood on a day-to-day basis in your neighborhood.
For example, the humidity level affects the dryness of
interior wood considered “acceptable” for finishing. In the
steamy Deep South, where 60% relative humidity is the
norm, fine carpenters have learned how to work with wood
