I do this groove and rod a lot the best for me are berillyum cooper rod. It is hard, it lube and very low surface oxidation with time a bit expensive and toxic I find a deal with 2,6mm dia and buy a lot. I was born close to a berillyum mine... * * *berillyum cooper* Class 4 (HT) 17200 Rockwell C 38-44 Serge Harel 2011/1/22 Delwin D Fandrich <del at fandrichpiano.com> > Yes.
