Three thin pieces make up the lamination of one arm and are glued on a form. The form is made of scrap plywood and cut according to the dimensions in the plans. Each piece is slathered in glue and then bent around the form and clamped into place. After drying, the clamps are removed. One edge is trued up and flattened with a jack plane and then the curve laid out on the opposite side and cut on the bandsaw. More sanding and shaping need to be done as well as the mortises for the tenons on the top of the legs to protrude.
