Bill's Osprey Project

Osprey Project | 2014

Bill inherited this partly-constructed project. The original builder built the parts as if he was creating a kit. Then he put together the fuselage and  tail, the wing spars and ribs, the ailerons, elevator and horizontal stabiliser. All the metal parts were welded, painted and labelled. The workmanship was high class. He used resorcinol glue which requires a very close fit between parts being glued.

This is how it looked when it arrived in my workshop.
