Now we join the elevation and azmuth assemblies, and do the wiring.
|
|
|
|
|
52
Both mechanical assemblies ready for joining.
|
|
|
|
|
53
Bolt the two castings together, running the wires. I had to drill an extra hole for the
additional wires I am adding.

This cable assembly is all new. It contains two video cables, two shielded control
cables for the focus pots and wires to power two cameras, and control one lens.
Note the bracket the wires are wrapped around. It is all new construction, and is
based on a similar bracket found in the original azmuth cable twist.

56
Test fitting the wires
|
|
|
|
|
57
Mounting the bracket using existing tapped holes.
|
|
|
|
|
58
Adding heat shrink tubing to keep the cable assemblies neatly wound.
|
|
|
|
|
59
Wrapping the wires around a piece of 1/2" copper pipe while shrinking
to set the shape the wires prefer to be in when installed.
|
|
|
|

It looks something like this before heating.
|
|

And the outside.
|
|

64
Wire one limit switch.
|
|
|
|
|
65
Wire the other limit switch.
|
|
|
|
|
66
Carefully dress the wires and tie them down so they cannot be damaged
by the moving parts withn the cabinet.
|
|
|
|
|
67
Connect the wires to the azmuth pot.
|
|
|
|
|
68
Mount the azmuth pot and start to dress in wires. Note the cable twist bracket and
stem in the azmuth shaft opening.

|
|
|
|
|
70
Install the heat shrink
|
|
|
|
|
71
Shrink it around a copper pipe the same as was done with the elevation cable twist.
|
|
|
|
|
72
Slip the twisted wire through the azmuth shaft.
|
|
|
|
|
73
Mount the wire in place.

Close up of the top cable coming out the elevation shaft.
|
|
|
|
|
77
Preparing the connector box for the elevation mounting plate. Note the
holes in the plastic box that allow clearance to the mounting bolts,
and the holes drilled and tapped in the arm for mounting the box.
|
|
|
|
|
78
Connector box attached to arm.
|
|
|
|

79
Run the wires through the wire hle in the box.
|
|
|
|
|
80
Mount the arm.
|
|
|
|
|
81
Strip and tin camera power and lens control wires.
|
|
