"My mill went down on a Friday afternoon. I got the crankshaft and rings the same day and we were grinding again before dark. That is why I don't buy anywhere else."
"I sent a photo of my old injector nozzle on WhatsApp and they had the right one priced before I even got on the bus. Straight service."
"We buy our UCP bearings and pulleys for two stamp mills here. Prices are on the wall, no stories, and the parts last."
