John Cooper, Kate Lawrence, Wayne Starsmore, Adrian Vanderplank and Jude Vanderplank. John drilled 2 lines of 6 holes. Could not drill too deep as they went through. John came out and Wayne went to the bottom to set up before ladder hauled up. Jude pressed the button. Phut then PHUT and finally BANG. There was some faffing involved here. Should be some spoil for next weekend now. 4 hours. John.
