On Wednesday, Nov. 15, my job was to drill about 40
holes to a depth of 18". The job was made more memorable
with 35 degree temperatures and 20 mph wind. It flurried
from time to time - the 1st snow of the year.
|
The holes were made every 8 inches.
|
Metal "feathers and wedges" were put into the holes.
They were hammered; one tap on one, and then one tap
on another - up and down the line to bring the tension
up together. They "tuned up" with pressure. The ringing
sound had a higher pitch on the ones that had more
pressure.
|
Eventually, the pressure opened a crack. This was
Thursday, Nov. 16. The sun came out, no harsh wind
and warmer temperatures. Mike is setting up the 32
ton crane, while I split the big stone into 5 pieces.
To get 7 preform blocks, I will have to saw 2 of the
split blocks.
|
I had to use a pry bar to open the crack wide enough
to get the rigging around a block.
|
Mike, operating Bennett's crane, concentrates as he
moves the heaviest piece off the truck. Monday, I
will saw 2 pieces with the water-cooled hydraulic
chainsaw. I will then move one piece inside to begin
carving. More pictures coming next week.
