I recently needed to make some raw blanks to turn some exterior porch components for an architectural restoration job. The job required the blanks to be 10-1/2" square x 2-1/2" thick when finished. Having mostly 4/4 stock, and narrower than 10-1/2", I needed to edge glue, plane, and laminate to get get my width and thickness. Sounds good so far, right?. Well, I rough planed and edge jointed one edge and glued up the pieces, I used 6 x 22 long pieces as to get 2 from each. After spraying water on the edges and gluing and clamping, I left them for 3 days, I wasnt able to get back them until them. My next step was to plane them and then laminate the pieces and clamp. Well, when I was planing them, one of the joints failed, it completely came apart , and the boards were fairly uniform thickness and flat etc, as they had been rough planed. So I took one of the other glue ups and sure enough, I was able to lightly tap the joint against a hard surface and it too failed..... Im kind of at a loss here. Any ideas?
