Now the interior of the panel has been roughly hammered out to finish the approximate shape.

A new series of edge shrinks have been taken to further develope the shape.

The rough shape is developed and now the buck must be used as a guide to action. By clamping the panel to the buck, low spots will reveal themselves. Low spots are raised by hammering and then wheeling them smooth. At this point minor imperfections in the smoothness of the panel are of no concern. The object is to keep making slight progress on each fitting and adjustment.
