each pair of posts and laid a tem- porary 2x4 flat along the ground. By sitting the fence boards on the 2x4, the board tops install in a straight line, and the 1-1/2-in. gap beneath them (once the 2x4 was removed) keeps the fence boards off the ground to reduce water leeching into the end grain. On this particular fence, we cov- ered the first layer of fence boards with a second layer, using the
same spacing pattern but stagger- ing the seams to close all gaps in the fence. The second layer of boards adds strength and rigidity to the fence. If you haven't chopped off the post tops, do so after completing the board installation. Jay and Jennifer opted to use copper post caps from SheetMetalCaps.com to decorate and protect the end grain of the posts. Post caps require at least an inch of avail- able post material above the fence boards, so keep that in mind when making the cuts. If you're not using post caps, you
We used a framing nailer with ring-shank nails to hang the first layer of fence boards.
During installation we sat the fence boards on a flat 2x4 to provide a gap beneath the end grain and to keep the tops of each section in a straight line.
