I will use silver for these lugs. One advantage of making your own is that you are in complete control of the lug/tube clearances so compared to bending production lugs a degree (or six as I've done...) the internal fit is far more compliant for silver. That said when I add the seat stay tops there will be some care in heat levels to not melt out the lug's silver filler. The stays will also be silvered (my usual method), and their top cap treatment is done with brass.

The next project has a unicrown fork, my first. Today I turned a sleeve for the crown race that will also be the reinforcement sleeve for where the hlades are attached. Both the sleeve and the blades will be brassed and this will be done in two steps. Again we'll see how good I am then This is why one builds for themselves many times before even thinking about for another. Andy
