<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">After talking to Danny, I think that a first step may be to get the 4 end dish assemblies on the CMM waitlist. The travelers I listed above for the assemblies are from 2013-2015 so I think that a re-inspection would be needed before we
had confidence in the parts. I would prioritize ED092, which did not have any recorded out of tolerances so it may be closest to being useable as a spare for the current pair assemblies. Two of the other end dish assemblies have out of tolerances of 0.001”
so maybe they can be easily fixed or accepted for use as-is?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We are still working to find any history on the bellows but I believe that if we think that they may be useable, we should plan to re-inspect them anyway. If someone is familiar enough with these bellows, it may be good to go look at them
in inventory to make sure there is no obvious reason that they would not be usable.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If we find that some (or all) of these parts are not useable for current CEBAF pair assemblies, I think we should determine if the parts need to be put in a long term storage or if they can be properly disposed of to free up space in inventory.<o:p></o:p></p>
