<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;color:black">Let's think about the overall length. The shell will need to be machined in order to fit between the dishes; what is the original length of the shell, and does this represent the
largest acceptable distance between the dishes? Or are there also weld preps which would further decrease the maximum length? This will will set the upper bound for the overall cavity length. The lower bound is a bit tougher as it would just be a matter of
cutting the HVs down to size until they fit. Is there a maximum length that can be taken off the HV shells to make them fit? If so, then that would be the lower bound.<o:p></o:p></span></p>
