Art, If the whitewood stave is DRY when the bow is built,I can see no changes ,(that I can notice). When tillering bows like this ,I look for any sign of the stave over-setting,if it does ,I simply stop work,and begin weighing again. Another indicator for me is during the heat treating process.If the wood still contains too much moisture,the belly will check badly,which does'nt happen when dry. JMHO God Bless
