About once a year, I stop by my friend's place, his hobby is Hauling away your junk and Metals Recycling.
I had some steel and brass to recycle and I swapped for a vintage USA made Arbor Press...he's got a shelf full of them.
ANYWAY, he asked me how I'd melt lead off of steel...He had a barrel (maybe several barrels?) of these same pins. Barrels outside, been rained on. anyway he met the tinsel fair and had enough of melting lead for a while.
I told him that I recently read a post about it (this one), and told him how you melted them. He wanted me to do it, I passed.
I think I have a lifetime supply of alloys, so I am not longer searching to add to my stash. Actually this spring I've been smelting what I have and trying to figure out how I'm going to store what I have. I have a neat idea about steel trash cans incorporated with my rear porch/deck/steps that need to be rebuilt. I have one trash can there now, with about 600lbs of COWW ingots on 50lb mini pallets. I live in town with a standard size lot and my garage space (and shed space) is at a premium...no room for another shed, but that would be ideal. OK, now I'm just rambling. Anyway, if someone is close by in MN, I bet my recycler friend would pay you (a portion of this lead) to melt his lead thread pins.
