Finally. After 5.5 hours deburring and dimpling and about an hour of priming, the top skins are ready to be riveted on. Time to work on the wings has been sparse the last few months, but making progress again.
Mounted a temporary ledge between my two tables to hold the c-frame for dimpling. Makes it a lot easier. The male die is aligned with the bench tops. Made it easier to dimple the long top skins with one pair of hands.
