SQUARE UP THE ARBOR
STEP 3
Now square up the arbor. This can be easily done with a large Carpenter’s Square, a tape measure, or even a length of string as shown below.
| “a” |
pilot hole | “x” |
carpenter’s
square
“y”
“b”
1.Measure the distance “a” at post tops.
2.Set bottom of posts to same spacing “b”.
3.Measure diagonal distance “x”.
4.Check opposite diagonal distance “y”.
When a=b and x=y, the arbor is square.
When the arbor is squared up, drive the second screw at the top of each post into the lower pilot hole in the header.
SQUARE UP SECOND SIDE PANEL & HEADER
Turn the assembly over so that the attached header board is on the upper side, with the free edge of the side panels on the ground or working surface.
Repeat the process to attach the other header.
ATTACH THE BRACES TO THE HEADERS AND PANELS
STEP 4
Carefully tip your assembled arbor to the upright position and check that the side panels are vertical and parallel.
Attach the four braces to the post, using the same technique as for the header boards: drive the 2 1/2” screw through the bottom hole in the brace so that it protrudes about 1/2”, and insert the point into the pilot hole on the inner edge of the panel frame. Then drive the screw in firmly. 1
When the position is set, hold the upper end of the brace firmly in contact with the header and drive the screw in.
