[QUOTE="Nightjar, post: 616209, member: 1414"] Never was a prolem brazing the tungsten to steel when making our speciality tools. The problem only arose when I was given a tin full of blunt tips that had been fixed to the holderd with a clamp locked with an allen key. The silver solder wouldn't run when heat applied? Will take a photo of our woodfire tools I knocked up in early 70's, still going strong. Another bit of advice I was shown. A container (half a steel 12gallon drum) some old engine oil) Tools were heated until they just began to glow then dunked in the oil and left to cool. To this day there is not a speck of rust on any of them. [/QUOTE]
