DKW Progress: Seat building

I'm finally feeling good enough to work in the garage, so I started the cafe seat for the DKW project bike.  This time I'm building it out of metal, not fiberglass.  While I enjoy the quick shaping of fiberglass, I get tired of spending week after week sanding bondo to get it to look nice.  So I'm hoping sheet metal will leave me with much less finish time.
