<p>[QUOTE=&quot;Kevin Mader, post: 25515618, member: 106826&quot;]I do recall reading about the pause you describe and that in part lends to my wondering about the way material flows as the hubbing process is interrupted.&nbsp; Does a partial imprint become mostly obscured as the process resumes where devices, especially the portion of the rod that makes first contact with the hubbing die (center), is mostly obliterated by the completion of the squeeze?&nbsp; It might explain why the outer devices are mostly intact while the inner devices see a majority of the expansion.&nbsp; That &#039;snap&#039; described by operators might attribute to the lateral movement in the setup (or be the result of it), even if the computer aided alignment forbids it.&nbsp; Somebody must have done a study we haven&#039;t seen especially if there were interest in eliminating some of the root causes...whatever they may be.[/QUOTE]</p><p><br /></p>
