Phil,

I have attached an update of the of the VV support rod analysis and mount mismatch study. Everything looks good and the modifications should prevent any problems. This documentation needs to be archived somewhere so it is not lost.

The drawings revisions for the design change are in checking and will be released for fabrication very soon. Note, there are no changes to the existing assy parts, only additions and substitutions.

Paul

Phil, Please note that with the new mount design, after assembly and welding of the 3 field periods, the VV supports will have a total additional radial mismatch tolerance of 0.329", that is the max additional deviation between any two of the 6 mount points must not exceed this value or the mounts will bottom out.
