So I save this wide maple plank for my drawer fronts, cutting them all from same board. Rough cut them all 1.5" extra, jointed a face and let them sit overnight. Came back and half of the ends have a 1 to 2in end crack in them. Tried filling them with epoxy mixed with saw dust but the crack is so tight cant seem to get the material in the cracks. So any suggestions?.... and why would a board be prone to checking so much.
