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. If your boom ever gets damaged
or destroyed we can send the specific replacement boom piece(s) required. Always apply an anti-seize
lubricant to stainless steel bolts that are using stainless steel nuts. This will prevent the two from gall-
ing together. Galling of stainless steel is common and has nothing to do with the quality of the materi-
al. Each bolt has a specific length for the tubing it is holding together this is critical so that only the
shank is engaged in the tubing. Use 5 washers per bolt to secure the bolt as shown in
figure 1.02
.
1. Apply a thin film of connector protector or a spray-on lubricant (i.e. Anti-seize, Noalox) to the male
engagement area of the boom sections. Failure to do so may cause the tubes to seize inside each
other.
2. Match the boom pieces as shown in
figure 1.01
below and slide each boom piece together until the
pre-drilled holes align.
3. Secure the correct bolts and washers onto the boom as shown in
figure 1.02
.
4. Repeat this for each section until the boom is completely assembled.
5. Secure the 7/16” eyebolt as shown in
figure 1.01
and
figure 1.03
. Note that in the event of a tight
fit, it is acceptable to use a mallet to drive the eyebolt in as shown in
figure 1.04
.
