<VV> &lt;VV&gt; 110 vs 140 Heads

[Jim Davis]

Atlas and Titian missile maintenance crews used
copper beryllium tools as they don't make sparks. 
The only prohibition was no eating with out washing
your hands after using the tools.

There's a myth about the toxicity of beryllium
alloys. The parts are not
toxic at all, it's the dust from machining them
that's the problem. So,
grind them with care, and with lots of coolant. The
only known route of
ingestion is inhalation of the dust. I assume no one
is eating the dust and
shavings!!
