How did Borglum make the statue of Confederate leaders?

But at Mount Rushmore, Borglum mounted a flat-panel protractor on each of the presidents’ heads with a large boom and a plumb bomb dangling from the boom. He had a similar device on a model. “His crew took thousands of measurements on the model and then went up to the mountain and translated it times 12 to recreate those measurements on the mountain,” says Bracewell. In red paint, they marked off certain facial features, what needed to be carved and how deep. To remove the remaining three to five inches of granite, the carvers used a honeycomb method. They pounded small holes into the stone using jackhammers and with a hammer and chisel broke off the honeycomb pieces. “They would just kind of pop off because the holes were close together,” says Bracewell. Then, the crew used a bumper tool with a rotating, multi-diamond drill bit head to buff the presidents’ skin smooth. When all was said and done, 800 million pounds of rock had been removed.

What was the name of the land that the Lakota occupied?

The Treaty of Fort Laramie, hashed out between the United States and the Lakota in 1868, declared the Black Hills to be Lakota land. But, in the 1870s, at the behest of President Ulysses S.

How did the drillers remove stone?

The drillers then removed stone to within six inches of the finished surfaces. The drillers carried Chicago-Pneumatic jackhammers, weighing over 75 pounds, with a hose for the compressed air powering the drill. These were not the easiest tools to handle -- especially when hanging in a harness on the side of a mountain. To position the drills correctly, the workers would keep their heels together and toes apart, and rest the drill bit in the V shape of their feet. Drilling horizontally, however, merely enforced Newton's law: an equal and opposite force swung the men away from the rock. In that case, they would first drill two holes at an angle, attach a chain to those holes using steel pins, and then brace themselves against that chain as they drilled. The drill bits didn't last long under these conditions; every few hours, a worker called a "steel nipper" would climb down in a harness to trade the dull bits with fresh ones.

How did carvers get close to finished surfaces?

Then the carvers would take over. By drilling a series of shallow holes in a closely-spaced grid, and then removing these grids by drilling obliquely -- a process they called "honeycombing" — the carvers got very close to finished surface. The carvers did the final finishing using smaller handheld pneumatic hammers.

How was dynamite used in Rushmore?
