At last, all piles are now driven and work starts to attach the top halves of the pontoon location piles. As the piles have bee driven to the required depth with the splices below mud level, this requires the mud to be dug out to get the coach screw inserted. The piles are aligned and held in place with a set of coach screws, the timber is so hard to screw into that Tam and Cyril decide to buy an air driven spanner (like they use in tyre places to tighten your wheel nuts so you can't undo them if you have a flat tyre!) as they have a more than adequate air compressor on the barge.
