It is interesting to compare the 'noise' level in this video compared to the previous posting where there are no machines running.
It always amazes me how dependent stonemasons have become on large machinery. This powerful mechanical 'hand' does the job of 8 men lifting these stones into place. Unfortunately there are those of us who didn't come here to watch heavy machinery move stones. Most of us see that every day in our working environment. What many of us came to see and experience was a transfer of knowledge, including a passing down of an inheritance of stone moving skills different to those used on every job site today.
Im just saying.
