Tool rod + segment, with welding heating until the cutter and cutter bar are red, and then use copper electrode with borax fill up that note to fill the gaps between the cutter and cutter bar, don't owe...
Well, after soldering, when he gets cold, you need to keep the heat down in the northeast in the winter
In the case of the blade of the tool knife, a flat pit is made of the same shape as the head of a knife. When welding, sit in the head and weld it with oxygen acetylene and copper electrode. When the head of the tool is welded, it should be buried in the heated lime, allowing the lathe to cool slowly so that it can reduce the possibility of the head cracking.
