Did you do anything on the inside edge of the 14 gauge (the lip that runs around the core)? It looks from the picture like it has a nice rounded edge to it. Also, did you have to add any "fill" to the outside edge (the joint between the 14 gauge and the 20 gauge) so you could grind a nice transition corner there?
