Back in the day, we always rammed our greensand molds with a hand rammer. Last week I tried using the new pneumatic rammer on a simple cope and drag for a gear blank, and the mold was way too hard. The casting came out with a massive swell. I guess the old way had a feel to it that the machine just doesn't get yet. Anyone run into this with the new gear?
