~ How to use timbers~
Timbers warps over time. This phenomenon is also a drawback of timbers, but the carpenter chooses where to use it and turns it into an advantage.
The timber warps forward. Of course, this also applies to board material, but the same rules apply to square timber.
Once you understand this rule, you won’t get lost in the timber, beams and rafters, window frames, window lintels, doorsill, kamoi, floorboards, etc. used for the foundation of your house. You can see which side is up, down, left or right. ..
