Come on guys. Read his message again. What I'm reading here is a desire to build the spar caps using Doug Fir rather than Spruce.
Mr. Wade. This isn't new ground. Others have done the same. Select your wood carefully. Keep in mind that when a spruce tree is selected to be used as stock for aircraft grade woods, it is felled and handled much differently from your average lumber yard wood, so inspect carefully for stresses in the wood.

My name is David Wade and My KR-2 is my first aircraft project ever. I have did careful research on my Center section spar material and I looked at AC 43.13-1B Chp 1 pg 1-2, table 1-1. I have decided to use Douglas fir 6 layer 1/2 inch laminate useing T-88 glue as a substitute for spruce for various reasons both personal and non personal.Before I do I wanted to get a few opinions and thoughts before I buy those pieces. Opinions are always appreciated. Mr wade
