Why don’t Japanese use nails?
While it’s true that Japanese builders didn’t have easy access to high-quality iron, there were other reasons for them to avoid the use of nails. Firstly, nails make wood more susceptible to rot. Moisture seeps in around the nail and down into the wood; this makes the wood less durable in Japan’s wet and humid weather.
What are the hardest joints in woodworking?
Found frequently on drawers, the dovetail joint is the Holy Grail of woodworking joints. The wedge-shaped pins and tails are cut on mating pieces which resist being pulled apart. The dovetail is beautiful and strong, but among the most difficult joints to execute.
What is the tenon rule?
The rule in Ellis’s book is two-fold. First, make the tenon one-half the width of the rail you’re cutting it on (a 2″-wide rail would get a 1″-wide tenon). Second: If that tenon’s width would be greater than six times its thickness, then you should split it into two (or more tenons).
Are dowel joints stronger than mortise and tenon?
