I had it burning for almost two straight hours. Cost me 4 needles to get to this and was a nightmare, the needles tend to get clogged when heating for silbrazin and I had to remove 3 of them and start again.
Keith I’ve fixed and never needed to PM him. He’s the master here and he has every detail available in everyone of his threads showing “how to”. Sorry
@Pancholoco1911 I’d still like to understand what you may have done to throw up the problems you experienced. This could only happen if you’ve not arranged to have the needle projecting above the tip of the vapouriser while silbrazing, leaving this appearance … The projecting needle is burned, but the crucial bit embedded in the skim of silbraze isn’t. When trimmed, the jet orifice remains intact, every time.
