<p>[QUOTE="Tom Maringer, post: 2740289, member: 7033"]Starting to come together. I visited the Carson City Mint museum, where they have a working press almost exactly like ours. I was hoping that they could help me understand the feeding mechanism. But it appears they don't use the feed at all, and are using the 110 ton press to do 150 ton work, which means that major (difficult to replace) parts are breaking. Ron Landis and Joe Rust (Gallery Mint) told me early-on that you always want to use a press well below its rated tonnage. If you run a 110 ton press at 75 tons, it will run millions of pieces and never give trouble. But if you run a 75 ton press at 110 tons, you may get away with it, for a while... but not for long. So, we're babying ours a little, saving it for smaller coins with lower relief, and doing the big coins with high relief on the bigger presses.[/QUOTE]</p><p><br /></p>
