Renting the augerYou may not have many auger choices at smaller rental stores, but if you go to a larger outlet or a home center that rents power tools, you''ll have to choose between a two- or one-person (see p. 70) power auger head, as well as select the correctly sized auger itself. Auger drills are interchangeable and come in 4-, 6-, 8- or 12-in. diameters. The one to choose depends on the type of posts you''re installing. Remember, the larger the diameter, the tougher it is to handle the machine. If you''re pouring 12-in. footings for a deck, you''ll obviously need the 12-in. auger (Photo 3), but for 4x4 posts, pick up an 8-in. auger. You''ll be able to get away with a 6-in. auger for steel fence posts. Keep in mind that you''ll need a larger hole (and a larger auger) if you''ll be filling around the post with concrete. The 4-in. auger will work for any small post that doesn''t antiqueelectricdrillrepair need concrete poured antiqueelectricdrillrepair around it. I use the 12-in. auger for all but the smallest posts because the extra space allows me to move the post around for exact placement. Jim/Stafford: Early design involvement on the part of the manufacturer is the best way to make sure the antiqueelectricdrillrepair resulting component will be reliable and effective.Jeff/Tollok: Carefully review your application requirements. Shaft material, hub material, transmittable torques, and bending moments can influence your selection of the proper locking assembly.Intelligent designWhat can DESIGNERS do when selecting and applying locking devices to improve productivity?Jeff/KTR: Obtaining comprehensive technical information will improve selection and performance. Find a manufacturer that maintains the quality of materials, dimensions, and surface finishes.Jeff/Tollok: Too often not enough questions are asked, and selections are made based on previous designs. Don''t use the same locking assembly simply because it was used elsewhere on the same machine or on a previous machine design.
