White woods really exceptable to boders. In ash they go deep. White woods not like osage that has lots of oils and raisins to stop interal rot.. Give it a try but likely if it's been out side. Those weather checks go really deep and so do boarers if you have them I your area.. I tryed ASH and BL POSTS. I split and tryed 6 or 7 post back in 88 never could find any that was solid enough to make a bow.
I did find some ash posts in a barn that had never been in the weather these were 45 years old. The wood boarers were there but I still made bows from them. I've found that it's better to fill the holes with saw dust a supper glue. And if it white wood back it. But Ive make HICKORY and just left them alone.
