by Victor A Boyce, CSN Here's a handy tip that all woodworkers
should know. This knowledge is most important when choosing
woods to be used in aircraft building that will allow you to get
the best pieces available The best wood to use when building an
aircraft is wood that has a perfectly straight grain. i.e. wood
where the fibers of the grain are parallel to the edges; it is
easier to work with, less likely to split, can be laminated and
bent into many shapes. Stronger structures can be made from this
class of wood. But is not always possible to obtain this quality
with a straight grain that runs the entire length of the piece
without some kind of grain runoff. So an allowance must be made
for some deviated or sloping grain however, if the grain slope
is too steep, the piece must be rejected. So the answer is to
measure the slope to determine if the piece can be used. The
grain slope must be determined and carefully measured on both
the flat and edge grain surfaces. These two measurements being
at right angl
