This morning, the students progress. And the afternoon, they are usually released.
Three of them, who do not live too far, manage to stay so we can continue the work.
The afternoon was devoted to:
- Repeat testing for the punch mark, the heat of the torch.
- To achieve the center punch in the plate of the monolith,
while being careful not to pass through matter, but only deformed.
And not that the shot deforms the whole plate, cool it quickly.
- disc bars that were welded to the first disc, to allow its hammering. The result:
Once the cake hit, put on another piece of the same section, we see easily that the hammering has expanded diameter, like that of a real rivet.
- to weld together the two plates that form the face of this monolith.
