塞尺都是成组的,但经常却只用到其中的几片。在我厂中,最常用的是厚度为0.03～0.05公厘的塞尺。因为这几种用得多,而尺寸又薄,所以最容易损坏。它们坏了后,全组塞尺就都报废了。后来我们学习苏联先进经验,利用化学翻新的办法,把过去积压的厚塞尺改制成合用的薄塞尺。但很快就把积压的厚塞尺都改制完了。工具科工人刘多礼同志又用同样的办法,将报废了的旧钢卷尺改制成塞尺。经过几次试验,已经改制成功。现在已将过去报废了的旧钢卷 Feelers are grouped together, but often only a few of them are used. In our factory, the most commonly used is the thickness of 0.03 ~ 0.05 mm feeler. Because these kinds of use much, but the size is thin, so the most easily damaged. When they are broken, all feelers will be scrapped. Later, we learned about the advanced Soviet experience and used chemical refurbishment to reformulate the backlog of thick feeler sticks into a compound thin feeler gauge. But soon the backlog of thick plug rule restructuring. In the same manner, Comrade Liu Duoli, a tool worker, reworked the scrapped old steel tape measure into a feeler gauge. After several tests, it has been restructured successfully. Now the old coil scrapped in the past
