器械司里，宋长平带着自己的火炮生产虚落座。龙腾小说ltxs520.com网
把宋长平独立出来之后，宋长平只带了以前跟着自己的火炮生产杏。
站在器械司的黑板前，萧铭将燧枪的结构图绘制了出来。
无论是火绳枪还是燧枪，这两种枪械都是滑膛枪，唯一不同的地方只在于火药的激方式。
火绳枪很简单，基本上和火炮的原理一样，只要得到枪管，这个技术对宋长平等人来说不是难题。
只是对萧铭来说，再生产火绳枪已经没有必要，而且火绳枪在野外对付骑兵也不能起到良好的效果，三分钟两的射击量，正如明末关宁铁骑的三眼火铳，临战不过两子弹，剩下的便是肉搏，而一旦火绳枪的火绳熄灭，还需要重新点燃，这时火绳枪和烧火棍没有什么区别。
而燧枪避免了火绳枪在射击时候火绳熄灭这样的状况，稳定性更高，这也是为什么燧枪很快淘汰了火绳枪的原因。
“总的来说，燧枪的枪机外侧分为击铁，主弹簧，扣簧，火药池四个部分，其中击铁用来固定燧石，主弹簧为击铁提供动力，扣簧则是燧石撞击的铁片，火药池用来预装少量火药引燃枪管里的火药。”
“而枪机内还有扳机，机心，阻铁和阻铁簧，扣簧片，内侧主弹簧，其中扳机用来击，机心保持和释放主弹簧的动力，并将动力传输给击铁，阻铁则是当有人扣动扳机时，啮合机心，然后将其释放，扣簧片固定连接到火药池上扣簧的盖子，使得燧枪机能够抵挡风雨，总得来说这个原理就是当扣动扳机在主弹簧上聚集强大的力量时，阻铁会与机心啮合。扣动扳机后，它会向前推动阻铁，一直到能释放机心的位置，并使得击铁推动燧石向前冲击。”
黑板上，萧铭指着燧枪的结构一点点讲解，宋长平等一众匠人认真记忆，将燧枪的构造全部刻在脑子里。
同时他们记下了黑板上燧枪各个构造的尺寸。
在宋长平看来，这枪击上的细小零件锻造倒是一件很麻烦的事情，无论是击铁，弹簧，机心还是扳机。
总体上将燧枪的全部构造讲了，这时萧铭说道：“现在你们可以提出难点了。”
“殿下，还是这弹簧的问题，如何让钢材具备弹性？”宋长平提出了最主要的问题。
在他看来如果没法制造出弹簧，这燧枪就无从生产。
这时萧铭笑了起来，他说道：“本来是不可以，但是现在可以了。”
“哦，为什么？”宋长平奇怪道。
“你们知道本王为什么要找钨矿，而迟迟没有动手生产燧枪吗？”萧铭问道。
宋长平等人摇了曳。
萧铭这时说道：“枪管只是其中一个问题，手工可以打造枪管，但是那时你们只能生产火绳枪，而不能生产燧枪，因为那时不可能有弹簧钢，因为弹簧钢需要碳锰这种元素才能生产出来，即便那时有了枪管，也没多大用，反而会浪费大量的人力物力。”
顿了一下，萧铭说道：“所以现在你们知道本王为什么一直偏执钨矿的原因了吧，不仅是为了刀具，这还附带弹簧钢的材料。”
