I eliminated one of the sides during the bending process.
It was due to too much moisture, I think. They did not break along the grain but crosswhise.
However, I decided to move on with the "not so flat" other piece.
I cut 2 sides out of it which are not mirrored !!! The next faux pas ?
I bent them and already, assembled the guitar body.
When you have the same spirit like me,
which means you take the wood just like you have it laying arround, you'll love the guitar.
I will post photos as soon as I finished.
