Whats Happening ?

Trevor has driving lessons.

While waiting for the falling tide to drain from the lock chamber Alistair gives Trevor a lesson in operating the RB crane.  As soon as the apron is clear of water John sweeps clean the cills.  Alistair once again uses the RB to lower the gate stop boards into place.  Helped by Trevor the boards are finally manoeuvred into place.  John and Alistair clamp the new boards to the remaining timbers and then drill holes through both so that threaded bar can be inserted and bolted tight.  In the meantime Adrian is selecting pieces of timber and cuts them with his chain saw roughly to size suitable for replacing the damaged apron.
