[Below] I stuck the two brackets together with double sided tape and sanded the rough band sawed edge.
[Below] Then I set my router to add some decoration to the outside edges. In this photo I’m setting the guide bearing of a Roman ogee bit to the halfway point of the thickness of the wood.
[Below] Only the top portion of the bit is used, giving the edge a concave groove.
[Below] The brackets get this treatment on both sides. It not only fancies it up, but also makes the piece look less clunky.
[Below] Now the top edge gets a slight chamfer to take the sharpness off of it.
[Below] Everything gets sanded to remove any rough spots on flats or edges.
[Below] Oops! When I sanded the edge of the bracket that attaches to the shelf I made it uneven. Running it through the table saw on my crosscut sled trues them back up.
