...finally got this clean enough to find this crack in the lower head tube lug.





I'm sure the ideal solution would be to get a frame guy to heat it up and drop some silver braze in there, then repaint the area damaged by the heat. Has anyone ever had a similar crack in what is obviously a high stress area ? Did you fix it or just ride it until it got bigger and more visible ? Am I wrong in assuming there is plenty of brazed lug surface still in contadt with the head tube and the down tube that neither is going anywhere any time soon ?

I'm asking for practical experience, not so much opinions, which I understand will be all over the map. Thanks in advance.
