LIMNMEDIA - Pan Axis Shaft & Bearing Fitment
This set of images shows drilling the hole for the 10mm shaft, which will serve as a shoulder bolt for the pan rotation axis.

At the same time, I’m fitting the bearings that sit between the bottom of the diving board and the top of the pan elbow.

Process
The 10mm hole is drilled to establish the main pivot point for the pan axis.
This shaft will:
- carry the rotation for the pan movement
- tie the diving board to the head assembly
- act as the primary structural pivot at this stage

Alongside that, the bearings are placed and checked for fit between:
- the underside of the diving board
- the top surface of the pan elbow

Notes
This is one of those points where alignment really matters.
The shaft, bearings, and surrounding structure all need to sit cleanly together so that:
- rotation is smooth
- there’s no binding
- load is distributed properly
At this stage, it’s mostly about:
- checking fit
- confirming spacing
- making sure everything stacks correctly

Context
This establishes the pan axis within the head assembly.
Up to now, a lot of the work has been structural. This is where that structure starts turning into a functional rotation system.
Why This Matters
This axis will carry:
- the tilt assembly
- the camera
- all motion above this point
So even though it’s just a drilled hole and a shaft, it’s a critical connection.
Getting this right early makes everything that follows much smoother.
