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.
John Cooper, Nigel Graham, Pete Hann, Kate Lawrence, Adrian
Vanderplank and Jude Vanderplank. Cool again, 10°C, and overcast with showers
getting heavier towards the end of the session. Started by measuring the
current depth which was 13m from the horizontal scaffold bars. Then Kate to the
bottom and 40 loads of mud together with a couple of newts and other critters
sent up. Also a bit of flowstone 150mm x 100mm x 25mm. At the end Adrian went
to the bottom to get a video record of the current state using his GoPro. Really
need to sort out the ladders! 2 hours. John.

John Cooper, Pete Hann, Kate Lawrence, Adrian Vanderplank and Jude Vanderplank. Cool, 10°C, and overcast with a light shower halfway through the session. Last weekend the hauling platform was extended by the addition of the “Diving Platform”. This enables a simple reach out to grab the spoil bucket rather that the awkward swing and pull required previously. Also, partway through this session, the bucket was transferred from the middle of the rope to the end as the haulback line was no longer needed. With Kate at the bottom, as usual, a total of 40 loads of mud and 4 of rocks were hauled out. In addition 2 small newts, 2 toads, 1 frog and a hairy caterpillar were moved to new homes. To complete the session one mix of cement was used to build up the platform at the base of the top ladder. This enabled the top clamps to be moved onto the next to top rung of the entrance ladder. Next jobs are to stop the mud slumping into the pit, which is now 1.5m deep, and to sort out the ever growing gap between the bottom ladder and the middle ladder! 2 hours. John.
