   2: Production Manual Abstract:
The Rota-sludge and the Stonehammer methods together form a package. Basically one drills with the Rota Sludge until one hits a layer with boulders or stones, then one uses the Stone-hammer to pass through this layer and finally one switches back to Rota Sludge when the boulders are passed.
Part 1 of this manual describes, step by step, how the Rota sludge and Stone hammer method must be used and part 2 provides detailed drawings of the equipment.
