I assume you're talking about torsion stiffness about a fore and aft axis, but which bending plane is this? Is there only one that is important? -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------------------------- List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
