My Simmonds Precision Work
After my Honorable Discharge
from the US Navy in August of 1962, I came home to Burlington and
began searching for a job. Finally , about March of 1963 I began at
Simmonds Precision in Vergennes as a Methods Engineer. I observed
how the assemblers were making the fuel gauges and I wrote up their
techniques, and at the same time tried to improve upon it while timing
all their actions. We made fuel gauges and amplifiers for the new
Boeing 707 passenger planes, the Kaman helicopter and later the Cryogenic
Nitrogen Fuel gauges and assemblies for the Apollo Command Module
that was used for the flight to the moon in 1969. We designed and
built them in 1964 and all solder joints had to pass NASA Inspection.
We used a lot of Teflon for the piece that was installed in the fuel
tank which had to survive very low temperatures. |
Below is a drafting
sheet that we used at Simmonds Precision. You can see that the company
was previously called Simmonds Aerocessories.
The headquarters was at Tarrytown, NY and the company had its own 2
engine airplane and a dedicated pilot. I flew there only one time.

These are the Apollo amplifiers which were then potted
with an epoxy foam to permanently seal them.
These are modules of a Frequency Synthesizer that we
built for (AIL) Airborne Instruments Laboratory.
They were also potted with an epoxy foam.
1963 April 16 - Simmonds Precision build electronic propellant
gauge for Apollo service propulsion system - Program: Apollo.
North American chose Simmonds Precision Products, Inc., to design
and build an electronic measurement and display system to gauge
the service propulsion system propellants. Both a primary and a
backup system were required by the contract, which was expected
to cost about 2 million.

The Company was next
called Goodrich Aerospace
