First of all, the Chinese circular partition door must be spliced if it wants to make a beautiful arc. Round-backed chair is similar to its chair ring, and it is directly spliced together by tenon joint, and about 5-7 arc short films are spliced together. This is not easy to deform and saves materials. Specific practices are as follows:
1. Measure the diameter of this arch first, measure it horizontally, or master the diameter data.
2. Then fix the center of the circle and the wood, draw an outer arc on the wood with the radius, and reduce the radius to leave the width of the arc door edge. Then draw an inner arc and draw both sides of the fan along the radius, so as to get the fan shape, and then copy it in turn.
3. Finally, refer to the arc tenon of the round-backed chair and connect the seams of several pieces of wood, which is the whole arc door. Don't completely cut off the wood grain path of each arc, it will be stronger and more beautiful.
