I have a bunch of thick pins. If I break them in half one has a red inside, copper I would assume. And the other is gold, would that be brass? Is there really pins made of solid gold? Should I process them separate or together. (The copper ones are fully plated )
Once you get the hang of these, they will pop out fairly easy with a small hammer. They will produce better than the average PC pin per 100 grams. I ran two lots of 100 grams each sometime back but can't find my data on them so I can't get any closer than I remember thinking they were better than the PC pins, and easier to remove.
