After making the CNC machine, I got a bit sidetracked with making weight driven, pendulum regulated clocks. The first one that I made was for my baby boy's first birthday present. This is where I discovered aircraft grade ply which I use to make Airframes. The super thin timber layers running in opposing directions and the fine grain is needed for strength in the small teeth of the gears. The Aircraft grade ply used here is a 5mm 10 ply...in the 5mm there are 10 layers of wood and 9 layers of glue!
