Gerry,
Hard drawn brass tube has high internal stresses which can be relieved by
heating in an oven for an hour at a temperature of about 300 degrees
centigrade under protective gas. Quenching with oil or water will barily
help softening because of its bronze nature. Plumbers have bending aparatus
for pipes, but I don't know to what diameter.
Wish you luck,   Willem
