John Cooper, Nigel Graham, Pete Hann, Kate Lawrence and Adrian
Vanderplank. Cool again, 10°C, but sunny with a slight breeze. Sorting out
ladders was the plan for today. Initially John hung a 10.3m electron ladder
down fastened to the scaffold bar adjacent to the pulley. The bottom rung
was still about 3m from the floor! John descended and used the hauling line to
attach to the top of the bottom ladder. This was hauled up a bit so the tape
joining the bottom and middle ladders together could be removed. Then undid the
bolts holding the middle ladder in place. The top bolt could be knocked in to
release the ladder but the bottom two could not so Adrian descended and cut
through them using a reciprocating saw. The now free section was carried to the
surface out of the way. Locations for fixing the previous bottom ladder in as
the new middle ladder were then identified before it was hauled to the surface
for drilling. Unfortunately both are on the left. It was then lowered back down
and the spot on the wall where the top anchor was to go identified and drilled.
The top fixing was then loosely installed. Using the electron ladder’s bottom
rung it was just possible to descend and mark then drill the bottom fixing. This
was loosely installed. A new section from a double extending ladder was then
lowered down to become the new bottom ladder. At the end of the day Pete
ensured the fixings were tightened up. We still need to put in a bracket to
hold the right hand side of the ladder securely in place. Kate was then sent to
the bottom to dig out mud that had slumped in. After a while Pete went down to make
sure she was excavating a suitable base for the retaining wall, I think he had
to keep her focused a few times! We lowered a piece of plastic board and a
stronger wooden piece for Pete to use as a retaining wall in the hope it would
stop the mud slumping in too much. Unfortunately Pete’s batteries all died and
he was unable to securely fix them to the walls. There was a mutiny at 30
buckets of mud and 2 of rock. 3 hours. John.
