Curve shape cut out from solid timber always challenge since it require large section of timber. It is not only hard to locate the fiber, timber will have significant check on surface since it contains so much difference in fiber tension depends on part of section in timber.
This can be solved by having two smaller timber laminated, much easier to find good fiber and also grain match. Seems like this approach can be develop further more by specifying timber grain in detail and how we re-saw to match grain!
At Daizen, we ensure client expectations and understanding of processes are met through all phases of our work, from structural design and engineering to fabrication of timber frames and assembly and installation.
