To make large piles of coal without a mess and waiting for glue to dry deep inside a pile I choose to sculpt a foam base first and test fit into the pocket and then coat with black paint full strength. I then wrap with saran wrap to protect the outlying structure from glue and place it in the pocket, add lots of full strength glue to the visible structure with a brush making sure to get it down in all sides.
I then add a generous amount of unwashed Conway Coal of any grade over the glued area, pressing the coal down into the corners, after pressing down give another coat. You can add glue down at the bottom of the pile for coal run off from the pile. When they dry remove from the pocket and saran wrap, you will find the glue still wet on the sides but will dry very quickly when the wrap is removed. You can then place your coal pile back into the pocket. I place a straw into one of the piles so my screw conveyor could go right into the pile.
