Assemble the intermediate arches “E” using # 20
-21 rafters, # 22 posts, # 23
braces using # 45 self-tapping screws.
To
maintain
the
correct
geometry of the arches, use
the assembled end as a
template, placing the parts for
assembling the arch on it.
5. ASSEMBLY OF THE FRAME (for the assembly diagram
Fig.3)

Connect the
# 40

long)
To EXTEND the frame by 6.5’ (2m), use sets of six 27 X
-crimp stringers and four
intermediate arches (Optional possible extension length is
19.5’L,
26’L etc.).

Install the
# 28
Side diagonal supports
between the
# 3
End post and the
# 26-27
