LIMNMEDIA - Boom Arm End Mockup

At this point, nothing is finalized—this is about understanding placement, alignment, and how the system wants to come together before committing to cuts and drilling.

⸻

Objective

The goal here is to:

• establish a potential pivot location at the end of the boom
• explore how the jib mechanics will connect
• begin defining the position for the pan rotation axis

Process

The square tube at the end of the boom arm is brought into position and used as a reference for the next set of components.

A pivot location is identified and tested visually and physically, giving a sense of how the jib section will articulate relative to the main boom. At the same time, space is considered for the pan rotation axis, which will ultimately support the camera head.

This is a true mockup phase:

• parts are positioned
• clearances are checked
• alignment is observed

No material is removed yet—this is about studying the geometry before making irreversible decisions.

Notes

This is one of the more important “thinking” steps in the build.

It’s easy to rush into drilling and mounting, but this is where taking a step back pays off. Moving parts around, checking relationships, and just looking at how things sit can reveal issues that aren’t obvious on paper.

Everything at the end of the boom carries forward into:

• camera alignment
• motion accuracy
• overall balance
*

So this is the moment to ask:

• Does this feel right?
• Does the geometry make sense?
• Is there enough space for everything to move cleanly?

This is still the cheapest point to make changes.

LIMNMOCO Context

This step begins defining the transition from:

• structural boom → functional head system

The pivot at the end of the boom will connect into the jib mechanics, and the pan axis will introduce another degree of freedom.

This is where the crane starts to evolve from a single-arm system into a multi-axis tool.

Why This Matters

Once holes are drilled and mounts are fixed, changes become harder and more expensive.

Spending time here—just mocking things up and understanding the relationships—helps avoid rework later.

This is where design shifts from idea to intention.
