Occupations | Sets up and operates single- or multiple-spindle boring machine to bore holes in wooden parts: Examines blueprints, drawings, samples, or written specifications to ascertain size, type, and setting of boring tools, stops, jigs, and guides to be used. Inserts specified number and size bits in chucks of boring heads according to location specified for holes in stock. Adjusts spindle locations and stops to regulate spacing and depth of bore, using rule or template and wrenches. Turns handwheels to move table and guides to center stock under bits and regulate depth of bore. Starts machine, places wood on table against guides, and moves lever or depresses pedal to activate pneumatic clamps that hold stock in place and to engage wood with rotating bits. Measures location and depth of holes and compares measurements with work order and pattern specifications to verify accuracy of machine setup. Stacks bored material on handtruck and attaches work ticket where specified. Cleans machine, using airhose and rags. May be designated according to machine operated as Boring-Machine Operator, Double End (woodworking); Boring-Machine Operator, Horizontal (woodworking); Boring-Machine Operator, Vertical (woodworking); Cluster-Bore Operator (woodworking); Gang-Bore Operator (woodworking). May operate boring machine to bore, ream, and countersink bungholes in barrels and be designated Bunghole Borer (wood. container). (references) |
| Sets up and operates boring machine to drill horizontal holes through earth banks for installation of pipelines under highways, railroads, canals, and other obstructions: Assembles and positions machine, augers, and casing pipes. Signals operator of crane to lower boring equipment into previously dug starter hole. Verifies depth and level of boring position, using surveyor's level and spirit level. Starts engine and moves levers to rotate and feed auger into earth, and simultaneously activates hydraulic ram that forces casing into hole. Retracts auger and forces earth cuttings back through casing to permit coupling additional sections of casing and auger. May operate machine which flushes and pumps earth cuttings from hole. May operate boring machine that drives pilot hole through earth bank and pulls auger bit back through bank to cut hole of required diameter. (references) | |
| Tends single- or multiple-spindle boring machine that bores holes in wooden furniture stock: Lifts and places woodstock against preset guides of machine bed and presses button to start rotating boring bits of previously set up machine. Holds woodstock against guides and presses button to lower rotating bits that bore holes into woodstock. Removes stock from machine and examines workpiece for boring defects, such as splits. May place woodstock in hopper that automatically feeds piece under bits of machine. May cut defects from sections of woodstock prior to boring, using cut-off saw. (references) | |
