I am mounting a mantel for a customer that is made of a solid block of maple and I don't want to drill holes through it. My thought was to cut a 45 deg. into the wood then make a corrisponding cleat about 1.5 inches. this would pull the piece into the wall for a tight fit and make it adjustible and removable. But I can't find a 45 deg. dovetail reverse chamfer bit. Why not? They have Ogee sets that have almost the same reverse profile, why not a simple 45 deg.?
