The Line Boring Book — 50 Blueprints included in this Training Program

All the blueprints in this collection are organized into groups. These designated groups are identified as follows.

MA = Machine Drawings. Includes boring bars, power drives, feed systems, boring machines and end boring machines.

TO = Tool Drawings. Includes boring machine tooling, machine mounting fixtures, wedges, sleeves, tapered collars, tool bit holding fixtures, flange facing fixtures, gun drilling fixtures, and many boring machine mounting fixtures.

IN = Inspection Tools. Includes large and small tool setting dial gauging instruments, how-to B/Ps on tool setting, how to build I D micrometers and extension micrometers.

LA = Layout. Includes trammel inspection systems and layout, laser layout tooling and systems, laser levering layouts and sight leveling parallel alignment.

HY = Hydraulic Equipment. Includes stationary hydraulic pumping systems, portable hydraulic pumping systems, hydraulic valve and hose layout for boring machines, end-boring machines and hydraulic power feed systems.
