楼主，你是高高高级钳工吧？！！太强了！！！！

ammovie 发表于 2009-6-16 14:16

楼主很强大。

顶啊，楼主太nb了，佩服精神，我做了个8槽的，不管用，郁闷的很。
有交流的加我QQ57030119

总结一下再DIY吧，DIY会经常有失败的。

gong00boy 发表于 2009-6-18 21:00

工具挺全的啊

aximpda 发表于 2009-6-18 21:08

比鲁滨逊好多了，到回18世纪，绝对工具美得人跳。

TAOGHUA 发表于 2009-6-18 22:34

hao 这是看到的最详细的

32# aximpda 80管说的是材料的型号，不是大小

好贴,学习了!

做双面的可以吗？因为我朋友开五金加工厂的，做双面比单面的简单得多。

双面可能数据要重算，输C,就是双面的。
