Attached trim tab to the elevator, drilled and riveted trim hinge. This was somewhat tricky, do make sure you use a straight edge (aluminum angle or similar) to align the TE of the elevator to the trim tab. Also the plans say to leave a minimum 3/32” gap between the inboard edge of the elevator and the outboard edge of the trim tab. To easily accomplish this I bought some cheap tile spacers. Make sure the gap is at 3/32 when the tab hinge is pushed as close as it will go( the slop in the hinge side to side) After completely attaching and riveting , everything moved freely and looked good to me.
