Seems like it has been a while since a graphic of the end of a log
with an overlay of cut boards positioned over the end of the log to
show how grain will be distributed as the log is cut. Sure helped me
visualize grain patterns for various names. Maybe associate it with
the not oft posted FAQ.
Do a google search for Forest Products Lab and Wood Handbook. They have in
the last few years published this document as a series of .pdf files, which
you can download. The graphic you refer to I believe is in Chapter 3 - page
4, however, this is considered by many to be the bible of wood science.
Everything you ever wanted to know about wood, and then some. Well worth
the time it takes to download about 20 or so .pdf's.
The Woodhandbook is available onlione for download chapeter by chapter
or as the whole book. Now, if you don't have a mondo printer or access
to one, Lee Valley sells a hardcover version of it.
Here is the Lee Valley one:
Here is the online version:
This is by far the best source for this information.
