This morning, we must continue to assemble the frame.
We begin to quickly trace the different stages of the riveting plates to determine differences between each operation. The punch mark will be given at 1 m above the ground and other gestures concentront the top of the monolith.
must also find ways to make the punch mark, with which tool. Some tests are needed.
It would finally realized with a hot needle on the scale of our rivet.
Since we obviously can not use an existing rivet of this size (diameter 20 cm), it must be switched fabriquer.Le rivet consists of a cylinder full metal (For the part that comes in front) and tube inside (visible on the sides). The rivet is hammered manufactured with two "pancakes" that will forge full, and the tube to the central part. To forge the patties, they must be welded bars to keep them.
A wafer is then placed in a fire.
When the right temperature, she went out quickly from the heat, put on the anvil to remove the scale.
batting involved two to shape the rivet. The operation is repeated for a while, and take turns batting (the masses weigh an average of 7 kg ....)
Our afternoon is spent visiting the exhibition of Oscar Tuazon and Eli Hansen the Art Centre Park St Leger .
