Create Concealed Shelf Brackets

What happens here

Obtain angle iron from a hardware store and cut it to the same length as the wooden shelves using a metal chop saw. On the table saw, make a 1 1/4 inch deep dado cut (recess) along the bottom edge of each wooden shelf. This dado should be positioned 1/4 inch from the back edge of the shelf and be wide enough to snugly fit the angle iron. This recess will conceal the metal bracket once the shelf is mounted, giving it a 'floating' appearance. Mark four pilot holes on the angle iron that will be used to secure it to the wall studs. Drill through the wood and metal to create these holes.

Goal: Cut angle iron to the shelf length and make a recessed cut (dado) along the bottom edge of each wooden shelf to hide the angle iron, allowing for a flush, floating appearance.
