It has been quite a while since we’ve updated the AT-10 restoration. Past updates have emphasized the historical aspects of the AT-10, so it is a pleasure to highlight progress on the wooden main airframe this time.
Restoration on a rare airplane like the AT-10 involves a great deal of parts fabrication, which has been ongoing, and parts making doesn’t always make for interesting photos. But recently, some visually significant progress has been made, so it’s a good time to produce an update on the restoration.
Most of what has been done until now was the restoration of the metal cockpit area and the aforementioned parts accumulation and fabrication. Now for the first time, we can show some new progress on the primary wooden airframe.
The first step in building a straight airframe is creating a fixture to hold components in alignment as work progresses.
Many components on an airplane like the AT-10 were longer or wider than the available wood material. In those cases, tapered joints called scarf joints were used to increase the gluing area of the joint and create a nearly seamless appearing joint that had far more strength than a simple butt joint would have had.
With a solid, straight fixture, and the parts fabricated to build an AT-10 fuselage, assembly of the structural frame has begun.
