Why the Mosquito drew on furniture and piano makers

Why not make an aluminium version of the Mosquito?

Wood allowed a light, strong aircraft to use abundant material and skilled furniture and piano workers who were not already fully employed by the war effort.

Later aircraft such as the Hornet are briefly mentioned before the discussion turns to the Mosquito's original wooden construction. Wooden construction gave the Mosquito access to skilled workers who were not already committed to the main aircraft factories. Furniture and piano makers brought techniques for producing strong structures with little weight. Wood was also described as an abundant resource that the war effort had not fully exploited. The design therefore combined a suitable airframe material with industrial capacity that could be brought into wartime production. An aluminium version would draw on a different set of materials and workshops, so changing the material would remove part of the original production advantage.
