not at all, I should have read the post better. Just mulling over how to improve it. If the eccentricity could be pinned down it might be made adjustable, but if it's different at diferent diameters there is little hope.

I recently did a little 3" Bernerd that had areas of wear on the scroll, all I could do was set it to a best average.
The jaws had also worn so the work was held at an angle to the axis so it desribed a cone, same as cone error in a telescope mount.
