One thought...I don't know if you have any scrap left from the posts, but if you have section- like enough length for a tennon, a mortise on the bottom and some meat in between, you can cut the post shorter and install the short piece to extend the post back to it's original length. Pin it from a side that is not seen, and then glue the two together as well. If there is any gap, fill it with wood filler. Then adz the two as a unit to make them look like they are one. You will see the cut line when you oil or stain the post, but It could be the best solution to fix the post. Brad_bb
