Stainless steel filler wire is common for joining 4130, etc. but if fillet brazing over it to make a prettier joint, stainless and brass are not the combo.
AFAIK havent tried it I have to borrow gear or have someone else do It My house is too small .
amazed at how fast the torch array jigs at the Gazelle Steel race frame factory made producing a large batch of frames in a Day.
they were lugged, it was 1988, when I visited Dieren NL.
