This topic may need to be moved to another department, but I'll post it here for starters.
Yesterday I was skimming through an older publication (2001) of Missouri Woods, published by the Mo. Department of Conservation; the purpose was 'to help identify major commercial wood species...native to the state'.
The guide is a fairly comprehensive layout of various trees, including growing range, bark ID, wood grain, wood properties, etc. What caught my attention was the comment that several groups of trees are lumped together by the industry, including oaks and hickories, that no separation is made between the two, and that without laboratory equipment or other evidence from the tree, its often not possible to separate the two.
Maybe this is common knowledge to some, but since I use staves rather than boards, this was new info for me. It also caused me to wonder about inconsistent performance and results from using boards. Any thoughts?
