I'm proud of you son. Back in the day of almost free wheel weights. We would call it a day after 2 five-gallon buckets. I'm still blending those 2 plus pound "Muffins" into the scrap I scrounge up nowadays. I Add some pewter scrap 1 or two pounds per 40 lbs of weight. My cast Dutch oven pan is not huge. Keep up the good work. It pays off big time long term. Uncle Mike in Ct.
