Hi again,I`ve just sat down and thought some more about welding/brazing.The last time I did any brazing was at school (Long ,Long Ago) and I remember having to get the the metal to "cherry red" before the braze would flow.I think "cherry red" is hotter than ARC/MIG/TIG welding and as the drop outs are brazed in their join may become undone when brazing near to them,but I quite expect one of the forum frame builders to put me right on this.Please.
