Hi,
I have a .678 RCBS round ball mold. It leaves a small but sure sprue. I cast up about a hundred from wheel weight lead and tumbled them for over 30 minutes in my industrial tumbler. They came out well burnished and with no mold seam visible at all but the sprues are still there. Tumbling might work for pure lead but I'm guessing that the wheel weight lead is too hard to remove the sprue from tumbling.
So, I would like to buy one of these drill-powered sprue cutters I have heard about.
If you have one to sell, please let me know.
Thanks!
Steve
