Hi Aaron & Earl </p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;">

<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;">
FYI- The conclusion was to tear down the Pair 4 which was leaking (some quick photos attached from this mornings 8:30 meeting )
</p>

The project will be interested to get the flange flatness and other measurements once it is apart
</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;">

<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;">
There are a few theories – however the discussion mainly was that the bolts torque now might be too high now – so it will be an engineering decision (see “bright “ areas in photos at the flanges Bolts)
</p>

<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;">
I am sure there will be more to come – however when Pair 4 arrives to the CMM – it should be treated as a high priority
