"Puzzle" is the next technological experience after "Wave". After cutting and drying the details in the microwave dryer, there was an equalization of the deformations and the gluing of the elements to restore the integrity of the log.
A lot of time has passed and it can be seen that the integrity of the wood is stable and without cracks.
The wood is oak and all available cracks occurred in the log prior to cutting.
Here, for the first time, linear pattern copying was attempted, with the workpiece on a rotating base.
