Lead blocks in the keel, a dry fit. Had to hammer the lead flatter since the casting form deformed as we were hammering the casts loose. First casts fitted nice, but the quality of them decreased with every pour. Hammering lead was an interesting activity. Two hammers were used, one in the left hand, the other in the right. Whilst rythmically bashing the lead, an activity good for Siberian prison camps of the past, we rediscovered one of the oldest forms of music: music of labour. It just comes naturally when you need to do physical, routine work for long hours.
