This is US Department of Agriculture publication. It's official title is > "Agriculture Handbook #72." Hi, Funny timing on this thread - I'd been poking around University of New Hampshire's library on this subject. "On Measuring Wood Properties" (M.E. McEntire and J. Woodhouse, Catgut Acoutical Society Journal nos. 42 [1984], 43 [1985] and 45 [1986]) collects a great amount of material on mechanical properties of spruce, such as for grain angles, grain straightmess, as these apply for violin makers. Plenty of formulae for the ambitious. I also found a publication which leaned a bit away from these properties as constants, focussing instead on testing individual spruce (and maple) trees and samples with a Shigometer; "Violin Woods: A New Look", Alex L. Shigo & Karl Roy, University of New Hampshire, 1983. It has not very much in the way of properties, though.
