Speaking of setup, holding the parts in position looks rather difficult;
the broken tab is only about 1/8" square. Can anybody suggest some sort
of putty that will resist brazing heat, hold the (very small) parts in
place and not sinter to something indestructible when heated? Maybe
glazier's putty, but that can get rather hard. Fire stop caulking?
modeling clay? Perhaps something made from household chemicals like
talc and water?

Welding putty. Sold at any well-stocked welding supply store.
