吕兵也不清楚在唐代应如何监管此事,他用现代观念给出结论:“匠人的职责是在作坊内,若制作铁器的过程中出了问题,自然该由匠人负责;但若出了作坊,交付于军队使用,此间再出现问题,便应由军队的相关人士负责,与匠人无关。”

“好!好!郎君这个主意好!”

老金头听后连连拍手赞同。

裴仲一没有说话,但浑浊的眼里陡然放出光芒,显然也是极赞成这个办法的。

通过这番交谈,裴仲一对吕兵大有改观,发现这位年轻武将并不像其他官员那样盛气凌人,言行间处处透露出对工匠的尊重……

裴仲一深受感动,本已僵死的心也渐渐重新温热起来,对着吕兵一拜,主动讲出了他前来军营的目的:“昨日金兄弟已将铁管的问题全部转述于我,我一听便知军爷深知钢铁制法,不敢大意,所以特来与军爷说明。而且军爷还托金兄弟送来了礼品,小老儿无功受禄,自是不敢怠慢……”

“些许心意,老丈无需客气。”吕兵摆了摆手:“老丈请讲!”

“想来军爷的铁管必有大用,所以才特意点名缝合需严密。这个问题要解决倒也不难,只需寻来硼砂若干置于缝合处,与铁管一同煅烧,再用铁锤细细敲打即可。”

吕兵听得“硼砂”二字,便知道他找对了人。这个裴仲一绝非寻常铁匠,见识不浅。

在现代焊接技术产生之前,古代焊接金属主要采用的便是汞、锡、硼砂、铅等物质,根据具体焊接的对象和要求不同,选择的焊接物质略有差异。

吕兵也不能确认每种焊接物的使用领域,但裴仲一既然能说出硼砂,便足以说明他精通此道。

“老丈手里可有硼砂?”吕兵顺着问。

“眼下没有存货,但寻来并不难,军爷若是放心,可将此事交付给小老儿。”

“正要劳烦老丈。”

裴仲一接着道:“至于铁管外形和管内堵塞的问题,并不是金兄弟敷衍军爷,实是小老儿考虑不周,没有交待清楚。按照军爷所需的铁管标准,可在锻打、翻卷铁片的同时,在铁片内夹上一根棍子,待铁管锻打毕后再将棍子取出来。如此,打出来的铁管自然端直,管内也不会堵塞。”

吕兵听罢,抚掌叹道:“妙!实在是妙!”

老金头听完更是猛拍自己的脑袋,责怪自己怎么就没想到呢……

“不过,用此法可杜绝管内堵塞,避免大量渣滓残留其中,但……若军爷是要管内像外壁那般光滑平整,却很难办到……”裴仲一继续道。

吕兵此时已经完全信任了裴仲一的工艺水平,虚心请教道:“正是要铁管内壁光滑如镜……老丈可有什么法子能办到?”

枪管的内壁比外壁重要得多,光滑平整只是基础要求,也是必须要满足的条件,否则就只是一根废管子罢了。

裴仲一低头沉思许久,才缓缓道:“要想清理内壁,单凭人力万难办到。小老儿曾听说有一种木车床,通过人的脚踏发力,牵动前方的一根钻头伸缩旋转……若有这种车床在,再将前方的钻头换成铁管内壁的尺寸,使钻头深入铁管内,当可清理铁管内壁。但小老儿也只听闻过这种木车床,从未见过实物或图纸,更别说从何处寻来了……”
