A lot of your wood workers would be better employed building office or barracks furniture. Or upgraded ones help build MTBs/power launches.But then, there was also production, too. From that standpoint back then, wood was probably cheaper and easier to work with, depending on the company
There were not that many high quality cabinet makers around and most (all?) of them were used to working with different woods than what aircraft used.
Nobody was having bespoke Spruce 20 seat dining tables or giant armoires built.
Through in the different glues and such and it is not that big a deal to train a lot of your workers from scratch.
This is what tripped up some European makers.
The aircraft makers were moving away from "wooden" construction as used in WW I and into more high tech stuff using new glues and techniques.
The fancy wood plane shown earlier required baking in an autoclave for a period of hours to set the glue and help impregnate the glue into the wood structure.
you may be able to build hundreds of tiger moths per year (or a few thousand J-3 cubs) but trying to build thousands of fighters a year may exceed supply.
