Pic 1 is a close up of the 1" x 3/8" spruce that is to be planed down to 1/16" at the very trailing edge. The close up shows how actually rough the timber is before planing and sanding. Thick black texta line is a marker to not plane through as it is already 3/8". The pen line is the 1/16" mark. Everything else is removed pass by pass until there is a crisp trailing edge. Clamped into place with the gussets on top.
