Brian Burns Testing Results on Our Spruce


Spruce that has been Cooked has a 21% higher Q after cooking on average. These are uncooked numbers. And Still they are stiffer than most Spruce even Adirondack and Italian Alpine. He says by feel ( which luthiers love to use) its a big difference, Cooking Adds 21% Higher Q
Cook at 200 for 2 hours PUT WIEGHT ON THE TOPS
wait a week and recook AT 200 as many times as you feel you need to get that bone dry feel and clear bell tone ring. Let settle and add strings
DONT TRY TO COOK BILLETS, Archtops or other large form wood stock . I am talking spruce here not hard wood.
Brian has been testing our wood
and below are the the results of the testing he has done over the 4 to 5 years. These logs are all Lutz ™ spruce. Most Spruce sold by other vendors for this area are Sitka. So don't be fooled buy from sprucetonewood.com for true Lutz or you are buying only Sitka. See the harvesting thread below for University Of British Columbia Forestry Maps.
