Out of all the winter cut white woods I prepped ash,maple, red oak , hickory was the most work the cadmium was like glue to get off I finally just milled the stave into plain sawn lams for BBH or other bows , I never cut a winter hickory again , summer cut hickory it just pulls off clean in one peace, but I wonder if BJ presure washer trick would work on hickory it would save a lot of work, you could always take it to the car wash....lol
