Building a Fireplace Mantel
Nail the mantel shelf into the cleats along the back. Use a short level to double-check the mantel shelf from front to back and nail the crown into the mantel shelf along the sides and the front.
Use a combo square to mark the reveal (spacing to the edge) of the surface molding along the arc. Mark the center of the arc. Layout the vertical edges of the two frames from center.
Cut and nail the surface molding in place. The miters at the arced horizontal piece will need a little extra attention. Use a couple of scraps to test the angles needed to make the connection or you can overlap the horizontal piece over the vertical and trace the angle. The new angle can be cut with a sharp utility knife.
Apply carpenter’s glue to the back of the bottom horizontal piece and bend it into place following the layout lines. When you like it, nail it.
After the stone surround is in place, mill a 1/4-inch-thick piece and bend it into place on the underside of the arc. Measure, cut and install base pieces or feet.
Add your favorite finish and the new mantle is complete.
