I would like to ask the predecessors who used the wooden well planer.

Do you care about scratching hard with your nails? What are you doing, collecting by plane? What nonsense Mujingfang? Anyone with some skills knows that this kind of plane can't be used. It is very important that you use good materials to make a planer, but the most important thing is to grind the knife and cover knife of the planer well, otherwise it will be difficult to plane a piece of wood. How about a smooth plane? Try using a piece of wood without stuttering. As long as the plane comes out straight instead of rolled up, then your plane will reach the top level. I believe that it is generally not up to this level. Please look at some tools used by Huizhou carpenters. It's called traditional woodworking tools, and Mujingfang is nothing. You can also look at the Baidu picture: Huizhou Woodworking, these four words, and learn about the most traditional woodworking in China. They are in Huizhou. Exquisite technology has reached the top level.
