CHAPTER TWO
SECTION 2.0
MOUNTING THE BOOM TO THE MAST PLATE
MAST PLATE-TO-BOOM OVERVIEW DRAWING
When you have finished assembling the boom, use clamps or cord to secure the boom in place onto the
sawhorses or whatever structure you are using to support the boom. By doing this, you are “locking” the
boom into a level position, which will make the leveling of the mast plate much easier.
The DB18E employs a special system, called the EZ-Eye, for both mounting and leveling the boom. The EZ-
Eye is also used in preventing the boom from shifting during high winds.
Figure 2.01 shows an exploded drawing of the boom and mast plate assembly, along with the EZ-Eye sys-
tem. This parts explosion is a useful referral tool as you complete the steps in this section.
