I smelted down a 5 gallon bucket of wheelweights over the weekend, the most recent pick up from my source. It wasn't full to the brim, let's say 4/5 full. It weighed in at 97 pounds as it sat, I broke it into 3 roughly 33 pound lots for melting on the turkey fryer burner.
The usual pile of clips was to be expected of course, and certainly some other junk, but in the end I got 49 pounds of usable lead; the rest was all steel, zinc, clips, or other junk (valve stems, hose clamps, etc. etc.) That's a new low; usually I have found about 60-70% of a bucket was usable lead, apparently now we're down to 50%. Additionally, most of the weights were the ones with the silver plasticized paint on them, which while they seem to work fine, is a real pain to melt down because of all the smoke and mess.
What are you all finding now?
Range scrap is starting to look pretty good... I still have about a 10 year supply of wheelweights but even so.
