Free of Heart Timbers

Structurally sound and commonly used as brace stock in timber frame construction, free of heart timbers are cut from the outside of the log, avoiding the heart wood.  This makes the free of heart timber less likely to check as it ages, and therefore some builders prefer it to the boxed heart alternative.  Usually smaller timbers (4x and 6x) are cut as free of heart timbers as it takes a big log to cut larger dimensions while avoiding the heart wood.  
Free of heart timbers start at $1.90 per board foot.
