I visited an Amish woodworker today to drop off some materials. And got to see a wonderful thing. Three families had gotten together to cut the 5-6" thick ice off a pond on their property. They had a gas motor powering a chain saw to cut the ice. They've built a wonderful ice house with 16" insulation on the ceiling, floor and walls. Everyone was helping to cut the ice and stock the ice house. It was 1/3 full when I stopped by, and can hold many tons of ice. He said 2000 tons of ice, I think. Each small perfectly square block they cut weighed about 20 lbs. There was a downhill slant from the top of the pond to ice house so they had built a sluice of wood and scraps of metal siding. The kids would fling these 20 lb ice squares onto the sluice and the squares then slide at high speed, with much banging, to the ice house, around a curve and into the ice house. They will work through most of the night to cut ice before the big thaw tomorrow.
