In the fourth day we did some grinding on parts for forestry machines we grinded away the scrape metal parts and then wash it in hot water and put the bushing parts who were cooled on -85°C and we put it inside the designated places and in few seconds they warm up and then the parts stayed in the designated place… Then we put pollyvinol around the part and taped it with a tape…Then we put the part in the box that was on the pallet, we lifted the part with a crane.
