1 The heavy gauge wires that support the raspberry canes are threaded through drilled holes in the granite posts. Wooden toggles anchor the wires on the end posts.
2 It baffles me that granite can break like this, but the snow that fell was very wet and heavy and when it accumulated on the canes, the granite could not withstand its weight.
3 Replacing a post is labor intensive. The posts are held upright by cement footings. The footings had to be unearthed and dug out. Each one is the equivalent of one bag of concrete mix.
4 Getting the footing out of the hole isn't easy.
5 Here's a footing with broken-off granite
6 Chhiring had to determine how long the replacement posts needed to be, as the granite surplus pile has varying lengths.
7 He and Pete carried away the broken granite.
8 The broken posts were loaded onto the tractor and....
9 Returned to the granite pile.
10 Chhiring found the replacements he needed.
11 Those heavy posts were carried and...
12 Loaded onto the tractor.
13 The posts were taken to the equipment barn where holes for the wire to pass through were drilled using a core drill.
14 Water is used in the drilling process to keep the drill bit cool. Drilling through such dense stone takes time.
15 When the bit finally worked its way through, the core was removed.
16 The core
17 The hole
18 Pete loaded the tractor with all of the tools for the job.
19 Gyurme measured the height of an existing post.
20 They were trying to determine how much deeper the hole needed to be so that the replacement post would match the others.
21 Adjustments were made and the granite was lowered into the hole.
22 More measurements were taken for accurate placement.
23 A temporary wooden bracing structure was created to hold the post plum.
24 More adjustments were made using a level.
25 Soil was shoveled back into the hole to make it less wide.
26 The concrete mix was emptied into a wheelbarrow.
27 Water was added.
28 And mixed thoroughly
29 The concrete was poured into the hole.
30 When the concrete dries, the wooden bracing will be removed, the holes filled in with soil, and the wire supports replaced. Let's hope that we'll have no more broken granite!
