Stearman Wings

We rebuild Stearman wings or wing wood kits, as requested by the customer. We use only Boeing factory drawings, and the original certified materials such as Stika Spruce, Mahagonyclick to enlarge plywood and nails. Rib gussets are die stamped, ribs are built on precise metal fixtures and spars are precision drilled.

If we assemble the wings the steel bolts are replaced. All hardware is fully inspected and steel parts are stripped, Cadmium plated and baked as required. The center section is assembled using a heavy fixture to ensure square assembly. The wing walk plywood is steamed and formed from one piece of 3/16” Mahogany plywood. It is not built of wood pieces. Wing tips are laminated just like the original tips, as per the drawings.
