A repeat of the Right Hand elevator skeleton so far; the differences for the trim tab part of the elevator come later.
First onto the spar go the reinforcing plates and platenuts for the hinge eyes between elevator and fixed stabiliser (with Duralac conpund between the steel platenuts and the aluminium reinfocring plate, to protect from corrosion in the future).
Then on goes the steel elevator horn (which, although powder-coated with white paint, also gets a thin layer of Duralac between it and the spar/rib), then finally the end ribs.
