DISCO DAVE'S TUNNEL GUIDE

Chapter 5 Digging and shoring

Phase 1 TOOLS

  Unless you're digging into a hillside it's an idea to begin with a downshaft. You'll need the following hand tools. A pick, shovel, spade, 1 or 2 buckets, a small trowel, a tape measure, a wood saw, a hammer, 5 or 6 inch nails, a club hammer and building materials. Dig a vertical shaft approximately 4 feet square to a depth of 6 feet then square the walls of the shaft as best you can before measuring up for shoring.
