<p>[QUOTE=&quot;Kevin Mader, post: 25515516, member: 106826&quot;]I agree that most of the more obvious doubling occurs at central points for Class 9 doubling, but it&#039;s not exclusive.&nbsp; For example, the RTY or the 20xx devices show the more obvious doubling relative to devices closer to the rim.&nbsp; I think that Roly Poly (Type 2) applies here.&nbsp; My speculation: the shape of the rod might be in play here as well.&nbsp; More movement will be seen where the tip of the cone meets the hubbing die.</p><p><br /></p><p>While the Class 6 definition does not preclude the possibility of a single hubbing, and while the distortion seen on the specimen does not rule out lateral expansion, given the date of the specimen makes me lean away from Class 6 and more towards Class 9.&nbsp; I do find it interesting that Coneca doesn&#039;t even associate with Class 9.&nbsp; I never noticed.[/QUOTE]</p><p><br /></p>
