The entrance to the factory was concealed by placing two short railway sleepers on either side of the hole and on top of these sleepers a notch was cut out. A timber box was then made with two groves on top which would fit into the notches cut out of the sleepers allowing it to swing like an axle. When someone was entering the factory a box could be lifted up and a stick put under it to support it and when leaving the factory the stick was taken out and the box came down into the hole. The entrance was then covered so that it could not be seen.

While the dug out was being prepared, Ned Fitzgerald was gathering all the equipment that was needed and these were put into the dugout. We are not sure exactly what equipment was in the factory or where it was all placed. There was a barrel lined with firebricks which were set in marla (a soft putty like substance). There was a hole of approx 4 square inches cut in the bottom of the barrel for the purpose if tapping to get out the molten metal. Firebricks were placed against the hole and a further hole was made through these blocks of approx 2 inches into the center of the barrel. This furnace was standing about 2 feet from ground level. Over the furnace a hole was cut in the roof of the factory into which was placed a foot long earthenware pipe which went up through the ditch to leave fumes out of the furnace.
