1.Lay two side uprights parallel, with the notches facing away from each
other. Lay a top upright connector across the uprights. The top
edge
of the connector should be flush with the bottom of the notch and
the ends
of the connector should be flush with the outside edges of the uprights.
Bore 3/8" diameter holes through the connector and the uprights.
Attach the pieces with 1/4"x3 1/2" carriage bolts.
2. Measure
in 16 1/2" from each end of a 48" outside foot and mark the foot's
face.
Lay out the assembly so the connector is facing upward. Align the
uprights with the outside foot. The bottom end of each upright should
be flush with the bottom edge of the foot. The outside edge of each
upright should be flush with the mark on the foot's face. Bore 3/8"
diameter holes through the uprights and the foot. Attach the pieces
with 1/4"x3 1/2" carriage bolts. The
outside foot should be on the opposite face of the uprights from the
top upright connector.
3.
Screw two 16 1/2" inside foot pieces to the inside face of the outside
foot. The inside foot pieces should line up flush with the ends
and edges of the outside foot. They should also butt against the
outside edges of the uprights. Screw an 8" inside foot piece to
the inside face of the outside foot. The piece should line up flush
with the edges of the outside foot piece and butt against the inside
edges of the uprights.
4.
Use 2" screws to attach braces to the inside faces of the uprights and
the foot.
5.
Make the second side frame to match the first.
for a product buying guide.
The notches in the side uprights should face away from each
other.
Use 2" screws to secure the connectors to the side frames.
Bore countersink holes in the center 2x4.
Blocking helps the connectors resist twisting.
Attach lattice to the sides and top.
Install screw hooks in the center connector.
Bore holes for the rebar anchors.
