These Doug Fir brackets are non-structural and will be have a paint finish but the joints need to be glued and mechanically fastened without visible fasteners. The keyhole method was chosen. The screw was fastened to the piece with the end grain and the keyhole cut in the piece with long grain. The keyhole is created with a router bit in a router with a plunge base. Plunge in, travel to just beyond the end location, travel back to the plunge location and plunge out. Consistent layout is critical for tight fitting joints.

After the brackets are assembled it will be difficult to remember where fasteners were applied. Grainchek will provide a platform for documenting methods in a way that can be organized and shared with those that may need to know how things have been done.
