question of how to finish the sides of the dial was a detail
that needed to be resolved. A number of methods were evaluated
to construct a retaining wall. It was finally decided to use
granite blocks 15 inches square and 48 inches long. Each block
had two cut sides and 4 split sides. The 15 inch limit
is due to the fact that this was the maximum thickness that
the splitter at the quarry could handle. There were 36 blocks
required, each weighing approximately 1125 pounds. Two blocks
are left out on the south side to accommodate the ramp. The
retaining wall is 150 ft. in length and weighs about 40,000
contractor was hired again to help place the granite blocks.
There was still one situation to be handled. How do you
position blocks that weigh 1125 pounds each?
A shelf was created
around the perimeter of the dial plate to within an inch of
the elevation required for the blocks. This required cutting
back on the north, south and west sides and building up on the
east side. The shelf was compacted to make it as stable as
over two weeks I was making ice cubes. These were made in 4
litre ice cream pails and were each 2.5 inches thick. A
total of 108 were needed with a number of spares. Needless to
say, three additional freezers were enlisted at the homes of
volunteers to store the ice while I used ours to manufacture
them. Once completed they were all moved to one freezer. You
may be wondering what this has to do with the granite blocks.
