A. Shop for, gather and organize the materials.
B. Prefabricate the parts as required and stack like parts together. It
may be prudent to leave parts slightly long and trim to fit once
measurements are confirmed.
C. Layout and dig the minimum 42” deep x 10” holes using a lever
augur or power augur—or better still, hire someone that specializes
in digging post holes. Double check the locations after the posts are
set and adjust part sizes upward if necessary.
D. Always place posts on 2-shovels of concrete. Set the outermost
posts first and confirm square by measuring diagonally with solid
blocks between the end posts. Conversely you could put up batter
boards that are offset 1/2” from the final post locations. Once the 4
corner posts are set as near to square as possible, attach a string line
offset 1/2” to the corner posts on the long sides. Level and align your
posts to maintain them in a straight line as you set in concrete.
Backfill with dirt or gravel immediately. You don’t
have to brace the
posts if you pack the soil or fine gravel tightly with your foot.
E. After allowing the posts to set for 24-48 hours, cut and fit the
Support Rails and fasten to the posts using fence clips and roofing
nails. The Support Rails should be 3” off the ground and level to one
another. Add a 3¼” Galvanized finish nail on the diagonal to secure
the support rails securely. Fit the Base Rails and Top Rails between
the posts but do not fasten.
F. Assemble the screens as illustrated. Cut blocks to help you
space the parts quickly and accurately while you secure the lattice.
Fasten the Top and Base rails to the top and bottom of the lattice
screen using the 3” Galvanized Finish Nails into the 1x lower rail and
upper rail. Fasten the rails to the posts using pocket hole jig and #12
Stainless Screws. Fasten to the support rail using 3” Deck Screws.
G. Trim the posts to height illustrated or slightly shorter if posts are
too short due to grade. The top of posts should be level to one
another in each of the 3 roof sections. Assemble the Post Caps as
illustrated and install with 3 ¼” Spiral Galvanized Nails. Fasten the
Rafters to the caps using a 3” Deck Screw at each connection. (you
may use exterior suitable waterproof adhesive on
the dowel to
reinforce).
H. Space Rafters on Beams to spacing illustrated and secure with
3” deck screws or 3¼” Spiral Galvanized Spikes. Countersink all
screws and nails.
I. Cut and Install the spanners to lock the rafters in place. Again,
use a solid block to place them quickly.
J. Cut out Braces from off-cut 2x6 beam and 2x4 rafter materials.
Fasten between posts and beams with 3” deck screws or #12
Stainless Screws.
K. Give your project a coat of stain, then fill any voids or holes with
exterior putty. Give it a second coat after putty.
