Interesting problem Charlie. Wagner has a web site, in the frequently ask
question section they list an 800 number and also give an Email address.
You might start by contacting them, they should be able to help you. Keep
us posted, there are a lot of us who need to better understand how to get
meaningful moisture readings.
plug in the common names of some of the species from your table, and see
whether the numbers in the table correspond to the green density or the KD
density. Your density for hard maple, the only species that you mention for
which I could find a specific gravity listed in the database, is higher than
the listed KD density, so it seems very likely that what you need is the KD
density and not green.
Note that many species show significant variation in dried specific gravity,
so the "book" value might not be all that accurate anyway.
If worse comes to worse if you're in the US the government will identify the
species for you for free. If you're not in the US they'll still do it for a
nominal charge if I recall correctly.
