1980年间，我在现场等待师傅比对图纸试装配件时，随手撕一张包装钢板的牛皮纸，速写师傅最美的瞬间，这个师傅姓宋。

“你会画，去技术科画图纸吧。”因为画这种小画，没想到我被分配去干起了机械制图的工作。而机械制图与画画是两码事，“机械制图”是用图样确切表示机械的结构形状、尺寸大小、工作原理和技术要求等，不能有半点艺术夸张。画图过程我常常想起鲁迅先生为了美观，画人体解剖图时的那一段“谬论”。但是，这位宋师傅，人家可是一位好师傅。

宋师傅是八级钳工，是当时这个行业中的最高等级。他特别细心，善于观察，提出过很多小革新、小设计、小建议。记得那时候，现场常听到有人喊：“叫宋师傅来！”只要他一到，所有的问题都不是个事。亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰亰
