A unique collection of full-scale measured drawings for seven excavators from the Golden Age of steam powered shovels. Full details of each machine are shown, including the internals of all steam engines, gearing, boilers, controls, and steering. The 3D CAD generated plans are suitable for scaling to any size for both display and working live steam models. Also included are chapters explaining in detail how steam shovels move, and how boilers and steam engines function. All plans are based on measurements of surviving machines, original factory blueprints and repair manuals, plus patent documentation of mechanisms. Options are shown for versions with traction wheels, rail trucks, and crawler tracks where they were available. The shovels included in this book encompass the range of sizes from small rotating shovels to huge railroad shovels:
