CHAPTER ONE
SECTION 1.0
BOOM ASSEMBLY
Our boom pieces are all drilled on a very precise drill press. This ensures that all the bolts are snug when
assembled. It is always better to be too tight than too loose. Always apply an anti
-
seize lubricant to
stainless steel bolts that are using stainless steel nuts. This will prevent the two from galling together.
Galling of stainless steel is common and has nothing to do with the quality of the material. Refer to the
galling information in the
Preamble section
of this manual.
Each bolt has a specific length for the particular tubing it is holding together. It is important that the
shank of the bolt is engaged in the tubing, since that is the strongest portion of the bolt. Use 5 washers
per bolt to secure the bolt as shown in
figure 1.02
on the following page.
Apply a thin film of a lubricant such as Anti
-
seize or Noalox to the male engagement area of the alumi-
num boom sections. Failure to do so may cause the tubes to seize inside each other. Match the boom
pieces as shown below and slide each boom piece together until the pre
-
drilled holes align.
Secure the correct bolts and washers onto the boom as shown in
figure 1.01
. Repeat this for each sec-
tion until the boom is completely assembled. Note that boom piece 10
-

-
52 has two
1/4”
drill holes on
the end that connects to the
1
-
3/4”
boom section, and
5/16”
drill holes on the end that the EZ eyebolt at-
taches to. The rest of the bolts are
1/4”.
Figure 1.10
in
Chapter One, Section 1.1
shows a detailed draw-
ing of the EZ
-
Eyebolt.
Secure the
5/16”
eyebolt as shown in
figure 1.03
and
figure 1.04
. This eyebolt is part of our EZ
-
Eye sys-
tem, which helps to level the boom and also assists in keeping the boom from shifting during high winds.
This will be covered in more detail later in this manual.
