I recently put together a case made of solid wood. Miter joints reinforced with Dominos(in end grain at 45 degrees.) I'm concerned about overall strength as well as wood movement. I know the Dominos will provide a fair amount of strength, but I'm considering adding 3 or 4 to the already assembled joints in a locking or pin fashion. In other words, the Dominos will be inserted through the sides(fro the outside of the case) into the top and bottom. The end of the domino will be visible, but I don't mind. Does anyone who makes mitered cases use a similar method? Is this overkill? Or not worth it? Are the mitered Dominos already in there of sufficient strength to not have to worry about it? I'd love to hear your opinions.
Thank you.
