为了节约木材，经过研究，我们采用了一种制造支柱接榫的新方法。利用这种方法制造支柱的接榫，不但能节约木材，而且省工。这种方法的操作也很简单。先将圆木的两边各锯一口，两锯口间的距离等于接榫的长度。然后一头垫以枕木，用力冲击锯口附近，圆木即折断为两根，其断口即形成我们需要的接榫。 In order to save wood, after research, we have adopted a new method of manufacturing pillars. The use of this method to make the joints of the pillars not only saves wood but also saves labor. The operation of this method is also very simple. First, saw each side of the log, and the distance between the two saws is equal to the length of the pick. Then a cushion was used as a sleeper and it was hard to impact near the mouth of the saw. The round wood was broken into two pieces, and the fracture formed the joint we needed.
