To provide clearance for the appropriate drain-slope and to increase the workshop length by several, valuable feet, a portion of the end wall was excavated. Some of the removal was used to complete the backfill of the interior stem walls. Later, this 1 meter deep, perimeter "table" will be finished with workbench and shelves. The remaining earth went to fill a hole in the neighbor's yard. By the completion of the dig the tally stood at 68 buckets, or 2,721 kilograms of Nashville Basin hard-pack clay chipped and hauled away. I completed the work by hand over two days. On the second day I ran out of swings so I rented a medium-duty, electric demolition hammer with a wide chisel bit. The work had to be approached horizontally, which was still tiring, but the tool increased my speed by 200%.
