《周礼·冬官考工记·轮人&輈人》
把股围长分成三等分，去掉一等分就是骰的围长。用火烤煤做辐的木材必须使它们一律笔直，把辐材沉入水中，入水的深度要均平如一。辐要直指牙凿，使蚤与凿密合，无须加楔子就会牢固了。
参分其股围，去一以为围，揉辐必齐，平沈必均，直以指牙，牙得，则无槷而固，不得，则有槷必足见也。
Divide the circumference of the hub into three equal parts, and remove one part to get the circumference of the wheel. When using fire to heat the wood for the spokes, it must be straightened out. Submerge the spokes in water, and the depth to which they sink should be the same. The spokes should point straight at the mortises so that the tenons and mortises are tight and secure without the need for wedges.
