Hi Thanks for looking,
Jerry, I am thinking about it. In some spots there is not much room to play with before hitting screw holes. It has to be a very fine border molding and you only have one shot at it because there is no room for corrections. The welding is around the pan bridle to add metal allowing a nice round end surrounding the end of the frizzen screw. Then there is weld pooled to fill the depression on the top of the pan to give the top a convex shape rather than concave. Another place I may add metal is behind the top of the flint cock to add thickness that can be rounded off.
