A suggestion for increasing the surface area of the glued surface, and possibly thereby the strength, would be to cut matching V-shaped kerfs fairly deeply into the joint-end pieces and then glue that. Requires some precision to make the cuts; I'm sure there's a tool out there somewhere that does this as I've seen the jointing using this in rafters and other rough construction. -------------- next part -------------- An HTML attachment was scrubbed...
