Most brushes I have seen were either attached with a rivet, or the wire was cast directly into the brush.

More like in EnviroNet.

However, going back to question. I consider it quite suitable for
TechNet. I too have wondered how a good heat and shock resistant contact
can established between graphite and copper.

Till now I have used mechanical clamp terminals, which would become
unpractical with small devices. Due to high currents, conductive epoxy
falls out. There is a possibility to use electroplating, but I have not
tried it yet.

So does anyone know any other good methods for forming a firm bond
between graphite and copper?
