> Well, Sitka is preferable because it is the highest strength/weight > ratio wood out there. yes, thats correct...or maybe that's correct. Look at the strength/weight #'s from FPL handbook chapter 4 pg 13 sitka spruce red spruce specific grav .40 .40 moe 1.57 1.61 compression parallel 5610 5540 compression perp 580 550 sheer parralell 1150 1290 ...pretty darn close I'd say. But the point I was trying to make is not that Sitka is "better" than Red, or Red is "better" than Sitka, but rather if you design with a particular wood in mind, and your design accommodates the nature of that wood, it'll work. For me designing for a local indigenous species which can be sawn by local sawmill, artisans who are guys like us, makes sense to me, especially since sitka availability in my area is a pain. > And just what is "tone grade spruce?" > > Terry Farrell > > you're right, my bad...tonewood is a dumb term...especially seeing how well selected pallet wood would probably work as "tonewood", as long as you designed appropriately. Actually, my last experiment board had enough pitch pockets to run a small turpentine factory...and it sounds great...because its about board structure, not panel perfection. ...not yank'in on ya Terry...just a different take on things, as usual.
