K just saying personal opinion.... Brazed frames went out many years ago in favor of the stronger welds that can be had with a MIG or TIG. I just am too old to recuperate easily from the injuries a broken frame could cause.
I had to remove a bracket that was brazed.... I tore through the tubing... It will stay together.... No Problem.... I am a old man too... I have been a master tool and die maker for many years...... You can see more of my work at;
