These are the bottom pieces screwed into position. It was necessary to use three separate pieces because my Ash timber planks are 2 inches thick. I found it was easier to deal with than a much thicker block of wood. When I am sure everything fits well I shall unscrew the whole assembly, and reassemble using plenty of waterproof glue/sealer. I find Tiger glue ideal and strong.
