Rummaging around in the garage looking for some threaded rod (all thread) to fix my riding lawn mower. Found about a dozen bars of solder. 40/60 cast into the bars. Please refresh my failing memory. Is the first number tin or lead?. And yes did get my riding lawn mower deck fixed. As I was rummaging through some stuff, found the piece I needed to raise the deck and get it off the ground. Had to file off some burrs but fit the existing hole on the bracket on the deck,used a hitch pin clip and made the adjustments on the nut which fit another bracket on the frame. Tested it out and worked fine. So all in all saved some bucks with the riding lawn mower and found some bar solder I didn't even know I had. Thanks for any help. Frank
