Practice and formula of traditional oranges.

Making this traditional stool requires a little basic carpentry skills, and it is not easy to do it well.

As for the "formula", it is actually not a formula, but the legs of the stool are divided into two different directions, and it seems more appropriate to call it "slope".

1, length direction: increase the size according to the ratio of 10%;

2. In the width direction: increase the size by 25%.

That is, if the length between two mortises on the surface of a stool (panel) is 75 cm, the width is 10 cm, and the thickness of this panel is 4 cm, then the distance between the two mortises under this panel is 1, and the length direction is 75+4×10% × 2; 2. The width direction is 10-4× 25 %× 2. Here, multiplying by 2 means that the slope is to both sides.

Please accept the above answer. If you don't understand, you can continue to ask. thank you
