If your wood was cut this winter I'd leave some extra width for lateral shrinkage. For a finished recurve bow, I'd want 1 3/4" finished width myself. Anything from 60" to 66" will work @ 26" for a nice hunting weight bow. You can use a drawknife to remove the cambium layer, but with hickory, you don't have to follow a growth ring. I often take a ferrier's rasp and smooth up a hickory's back. But if you like a camo effect, you can leave a bit of cambium here and there for that using a drawknife. Good luck...….Art
