The only thing I am going by on any of these woods is smell, and chemical reaction. The lightest color is what I suppose is Maple. It is maybe 3/4 wide, and 1/2 thick. The core is what I suppose to be mahogany, as it is darker, and sands to almost a pink color, and smells "Spicy". The core lam is about 1/8. The belly is for sure Cedar, as it smells like cedar, it is also 1/8. The "Maple looks to be maple, and when hit with baking soda and water have very little color change, so there is low tannin's, like maple would be. Tyke tied a string to one 50 inch section of it and threw it on my tiller rack, and pulled it to 27 inches before it broke, but that was just a 3/4 X 3/4 board. It ended up breaking at a run-off. I'll post some pictures when I get home. I have never built a Lam bow either.
