I did some heat treatment to straighten the stave and got some cracks in the limb in a few areas of the belly. Limbs are 1.5" wide, no floor tillering yet, just the stave worked down to rough dimensions. I sanded the cracks in the belly down until the limb was a tad under 1/2" thick. Now im wondering if these will be a problem as they still havent disappeared. They dont go all the way through to the back but they are deeper than i had hoped. I sanded them so you could make them out in the pics. They are wide enough to catch your fingernail just barely. To those of you with a lot of Yew experience what are your thoughts, will these be a problem?
