Step Five: Saw into pieces

(This is going to be a really hard puzzle. It even flummoxed Santa a bit while he reassembled the first few pieces for this picture. Already hard to tell which is right side up since both sides have paint and art on them. Also, the thick wood is tough going making curves. Note scorched spots in tight turns. They'll be sanded and painted and finished later so as to not needlessly give any clues to sharp-eyed assemblers.)
