Tonight, I commenced the final step; the big glue up/assembly. Here I am starting with the wings which will then need to be clamped to the back frame. The unit(wings and back frame) will then be attached to the seat frame and, after some fine tuning/sanding, the chair will be ready for my wife to finish. I saved a small cut off of the original wing rail to use as a clamping block. The block is prevented from sliding with the help of some grip tape.
