Hey Bob, welcome aboard!!Naw, don't braze 4130:1. It's discouraged in FAA documentation.2. After you braze it, you can hear it saying "tink-tink-tink", a sign ofstresses and not reassuring, take it from me.3. If you braze 4130, you will have to put up with several hundred emails ofvarious intent and quality from our beloved group
