my one man tire shop (no lifts, just floor jacks out front in the elements) source continues to come through for me. Wednesday I stopped by with my dolly, flat shovel and four five gallon buckets. He had one of those small PVC barrels (maybe eight gallons) over flowing. I wrestled it onto my dolly and struggled to get it tipped back and moving. Rolled it outside onto a concrete patch and set about trying to tip it over and dump it. After some effort I finally got it dumped and set about shoveling the weights more or less evenly into the four buckets. Ended up with each slightly less than half full and weighing 82#, 70#, 70#, 60#, for a rough total of 282# minus the plastic buckets (and barely reliable mechanical bathroom scale).
After sorting I generally net 45% COWW, 8% SOWW, 39% FE, 8% ZN. For reasons yet to be determined this haul is at least 50# heavier than usual, even after considering the heaping full barrel. He did mention someone had dropped off a bunch of unwanted lead wheel weights so my lead % may go higher with this haul. Cost to me was $25 plus gas for a 12 mile round trip. And life is still good.
The moral of my story is don't waste time at the bigger well known tire stores. Shoot for those small independent shops who are not answering to some woke corporate office.
Once I get it sorted I'll report my %s, but not until it cools down a bit. I'm still sitting on 5/8 of a bucket of sorted weights. Just too dang hot for smelting right now.
