Archadeck of Suburban Boston frames the curved edge of a treated-wood deck set on grade.
With joists running long, Eric Roberts scribes a radius curve onto the joist ends using a simple string-and-pencil compass.
Roberts makes angled cuts on the joist ends in place with a circular saw.
Roberts finishes the bevel cuts on the joist ends using a recip saw after the circular saw bottoms out.
Roberts cuts deep kerfs into the treated 2x8 that will form the edge framing for the deck, to enable the member to bend around the radius curve.
Roberts makes closely spaced kerf cuts at the end of the framing member, which will have to curve more tightly at that location.
Roberts pushes the band joist into position around the joist ends.
With a pry bar, Roberts matches up the top edges of the deck joist and the curved band joist.
Roberts fastens the curved band joist in place with a nailgun.
Roberts strengthens the connection using LOK structural fasteners.
Where the wood-framed deck passes over the concrete paver patio, the members are notched for a nice fit.
