- Part 4: Splitting Granite for the Retaining Wall
- The mason on-site installing a retaining wall, Hector, shows Bob how to split a piece of granite that is too large and heavy to use as is. Using a hammer drill, he drills a series of 4 holes about 2 1/2 to 3 inches deep in the stone, all lined up in the direction he wants the split to occur. And he puts small metal rods called "feathers and wedges" into each of the holes. Then, using a striking hammer, Bob delivers a series of blows, hitting each hole an equal number of times until the stones begin to audibly crack and pop. Once it's split Hector can pick it up with his little tractor and set it into place.
Bob works with the Quechee Lakes Development Company to build a residence that hearkens back to the past yet satisfies the needs of a family in the new millennium.
