Hi Barry,

Remarkable! But when I opened the macro, oh my! Have never used visual programming tools, so this is totally new, but your example is much appreciated.

Here I go, sticking my foot in something I clearly do not understand... It seems like the centerline ought to be tangent to the top roller's larger radius, like you've done on the bottom roller. Or maybe you're just taunting me to figure it out and fix it myself... I suspect that when you added the thickness/diameter, you updated the bottom rollers but not the top. c'mon Larry, spot the difference!
