Test Assembly
85
The center "iron", wound coil, indicating needle, and end supports
were carefully assembled together to check clearances, etc.
Balancing Act
86
Notice the Indicating Needle is still bare aluminum color.
Before it was assembled together with mating components
shown here, it was meticulously balanced. The wound piece
of wire at opposite the pointer is a balancing weight.
After the needle was painted black, the mere weight
of the applied paint threw off the balance totally.
It had to be completely rebalanced. In up coming photos
showing the needle painted black, notice the wound piece
of wire is moved back about an 1/8th inch to compensate.
88
Opposite indicator end parts. Sapphire jewel bearing assembly
shown threaded into center of the fabricated phenolic bracket.
90
This end of the meter movement is adjusted to allow the
indicator Adjustment Bracket to be nearly vertical at
opposite end, positioning the needle as close to
"zero" on the meter scale as possible.
