In most modern metal shops, you’ll find both a lathe and a vertical mill. Both machines function by removing material from a block of metal—the "workpiece." The key difference between the two is how the workpiece is handled. On a lathe, the workpiece rotates, and is cut away by a knife tool. (Typical products of lathe work are "turned parts" such as spindles, bearings, screws, washers, and circular blanks for gears.)          On a milling machine, it’s the cutter that rotates. The workpiece is clamped to a table that is moved by precise amounts in two axes at right angles. (Typical mill products are flat-surfaced blocks of metal, like a cube, sometimes drilled for spindles or dowel pins, often tapped for screws.)           Both the lathe and mill are incredibly flexible machines, but neither is capable of doing useful work right "out of the box." Both call for a number of accessories for holding the workpiece, as well as a selection of different cutting tools, drills, reamers, etc. Unlike lathe turning, which has not changed fundamentally in the past 100 years, milling in the small shop has been changed radically by the recent introduction of bench-top machines.          There are now so many different milling machines that insider information has become even more important. In this work, Choosing & Using the Right Milling Machine, Richard Rex provides everything needed to choose the right type of mill—knee-type (Bridgeport) or bench-top—and properly install it depending on the type of work you’re doing. With suggestions for finding, installing, and using the essential accessories, including digital readouts, this work is a must-have for model shops around the globe. And it’s the perfect companion work to Choosing & Using the Right Metal Shop Lathe.             Features Covers different types of milling cutters, including end mills, drill bits, reamers, and slitting saws.Introduces information on the add-ons that get a shop operational with the least delay and expense.Instructs on the installation and use of three popular accessories—table power-feed, digital readout (DRO), and rotary table.Provides a workpiece tutorial that demonstrates many of the commonplace milling routines—ideal for first-time users.

This book meets three needs that are common to hobby metalworkers. A better understanding of what accessories and tools are available, helping you choose the ones that can make a real difference to the way you work and those that are likely to end up idle on the top shelf. How to make a range of practical, effective small tools and accessories, with an emphasis on those that cannot be simply or cheaply obtained ready-made.

Investing in a new metalworking lathe is a big step for any shop (especially home shops), where there’s usually no one around to help. Once the lathe is up and running, you should theoretically be able to make the special items you previously did without (or paid through the nose for), such as shafts, plain, tapered or threaded discs, bearings, and so on. But if you are new to this, you’ll want to know a lot more than you can learn from the salesman or the manual. Does the lathe really match your needs, and if so, how much?Choosing & Using the Right Metal Shop Lathe is an essential source of information for lathe buyers and users at every level, from mini-size tabletops up to industrial machines weighing half a ton or more. It answers the question of what else you will need to get useful work from the machine. For instance, what comes as "standard equipment" with the lathe? Most include a chuck (usually a 4-jaw independent, not the self-centering 3-jaw you’ll want to use most of the time), maybe a faceplate (rarely used), and a 4-way toolholder you will probably swap right away for a more sensible design. Never included is a tailstock drill chuck, an essential accessory you will need from day one—and the same goes for actual cutting tools. Almost certainly, there won’t be a digital readout (DRO), which used to be regarded as a "maybe-someday" luxury—but not anymore.The work talks about cutting oils, cutting speeds and easier-to-machine materials, and it cautions against buying sets of anything, vs. buying the one accessory you’ll truly need. Finally, there are chapters on building a tailstock drill press, a special toolpost for easy screw cutting, and a precision grinder for lathe tools that can be made from oddments of material in a couple of days or less.           Features Differentiates between the truly essential features (screw-cutting) and the nice-to-have (power feeding), spindle speed selection from a gearbox (typical) or continuously variable (more convenient).Offers advice on screw-cutting US and metric threads, and handling the machinist’s most trouble-prone actions, such as knurling and parting off.Provides a workpiece tutorial that demonstrates many of the commonplace lathe routines—ideal for first-time users.

Storytelling is an ancient art. At their best, stories provide a very personal and engaging way to pass information, experience, insight and imagination from one group to another, from one generation to another. Tool Tales is full of such stories. Its author, Herb Kean, is a noted tool collector, dealer, restorer and author (as well as renowned raconteur). Here, he has culled from magazines, journals, newspapers and encyclopedias 50 of his best stories and "tips" columns, written over the course of his long career. These stories range from whimsical tales of trips taken in search of old tools to more technical pieces detailing the "how-toΓÇÖs" of solving many a knotty tool-related problem. Full of valuable information to help the reader in buying, selling and restoring antique tools, they are also full of wit and good, old-fashioned fun.

Once again, Ken Cope has produced a major new reference work that broadens our range of understanding of the history of technological innovation. This is the first book to identify American lathe builders operating throughout the 19th and early 20th centuries. Written in the style of the author’s previous groundbreaking books on the machine tool industry, this encyclopedic volume provides the collector, user, and researcher with invaluable information on over 330 lathe builders, many of whom have previously gone unrecognized by researchers. More than a thousand illustrations, taken from original catalogs and periodicals, trace the development of the American metal cutting lathe from the crude, handbuilt models of the early 19th century to the fast, powerful models introduced in the early 20th century for use with high speed steel cutting tools. Dozens of early lathe accessories, such as gear-cutting attachments, are also identified and illustrated for the first time. In addition, the book contains a glossary of terms used in describing the various lathes
