Hi Russell: I think it boils down to economics. To spend the time and energy to reclaim by unwinding the copper wire from a steel core bass string to recover a few ounces of a non-precious metal might not make sense. Since tuning pins are steel, and in small amounts they probably have little value. I can remember however during WWII when scrap drives counted on small quantities by many people to help the war effort. During those years everyone pitched in, but alas, those days are gone and the drop in the bucket piano technicians could or would contribute would perhaps be insignificant today.... Mike Kurta
