Vince and Roz.
Back again! Another look into the space beyond, it becomes more enticing every time I look at it.
6no. holes (5no. to 400mm and 1no. 550mm length, 12mm diameter) were drilled and filled, spaced to shake-up the calcited rocks and blocks of conglomerate. Fired from the ‘lake’ chamber, no wetter than it was yesterday evening. All sounded good, flying rock was heard. Should be stuff to clear on the weekend.
