Estelle Sandford, James Begley, Mark Denning, Martin Grass
1.5hrs
Mark drilled several 12mm holes in what looked like a shelf. 1 went right through, but the rest were ok, so Estelle and Martin then went in to place the bang, we used 3 of the holes and 20gm and 5gm to join them. Once set, it let off a healthy bang, but no real breeze outside so air didn’t show signs of clearing particularly quickly so we left for another day.
Kevin emailed photos next day to say he had had a look and cleared some of the spoil out of the way, but hadn’t done much damage, so need more bang.
