After a bit over 35 years of dragging a pipe wrench around and doing all kinds of soldering jobs and even some lead & oakem work I have a decent sized pile of different solders and pure lead from my trade time. The latter end of my working was with the `lead free` solders. I unwind a few wraps of this stuff around my hand and add it to my 50/50 alloy mix in an RCBS 22 lb. pot then bring the temp back up and check it for what I`m looking for.Robert
