Thanks mp--I wasn't aware of this thread until I saw your recent post.
Ragarding the chart:
It is in Excel.
It combines all of the species (65 total) from the weight charts in the Z 133.1 2006, Blair (Arborist Equipment), and the Sherrill catalogue. It also lists weights for each of these species for 10 - 80 inches in diameter (the other sources go up to 24, 36, and 36 inches respectively).
There are three worksheets (see bottom left of the attachment in mpriley02's post, above). Each worksheet has all of the species, but the first worksheet has weights for 10 - 80 inches, even inches only, and prints on three pages. The next has weights for 18 - 72 inches, even inches only, and prints on two pages. The last one has weights for 14-36 inches, even inches only, and 37 - 72 inches, odd and even inches, prints on four pages.
