Harold Hall – författare

If fear of the unknown is all that is preventing you from embarking on the satisfying hobby of model engineering, then this is the book that will banish your concerns. Author Harold Hall has established his reputation as a mentor to tyro model engineers through the pages of Model Engineer magazine and Model Engineers' Workshop, of which he was the editor for a number of years. This book assumes no previous experience and using the medium of twelve lathe turning projects will lead prospective model engineers through all of the basic techniques needed to tackle ambitious projects. All of the projects are extensively illustrated and full working drawings accompany the text. Once followed through, the reader will have amassed a wealth of practical skills and a range of useful workshop tools and equipment.

Sharpening workshop tools is probably the most diverse of all workshop activities and the one that is least understood by the majority of workshop owners. This is not unreasonable in view of the wide range of equipment suggested for the task, ranging from the complex, typically an industrial tool and cutter grinder, through to the humble off hand grinder. This book illustrates how most sharpening tasks can be carried out using an off hand grinder and a few simply made accessories, whilst doing this to a standard comparable to that achieved using much more sophisticated equipment. A lack of understanding of the processes almost certainly results in the workshop owner attempting tasks with far from perfect cutting tools that can diminish the satisfaction of a job well done. With the information in this book this situation can be avoided and working with blunt tooling should be a thing of the past.

This book provides the detailed knowledge you need to successfully choose, install, and operate a milling machine in your home workshop. Heavily illustrated with color photographs and diagrams, understand which accessories are essential and which can be postponed until your activity demands it. The usage of each machine and accessory is explained in detail for the vast majority of applications in an active shop. Discover options for holding the many diverse shapes and sizes of work pieces that will inevitably surface during your machine's life. This critical task is by far the most important part of learning to use the machine. The Milling Machine will arm you with decision-making skills on which method is best for any application – whether to use a vice or an angle plate, mount the piece directly onto the worktable, or even produce a fixture specifically for the task. With the work piece set up and ready for machining, this book will show you the correct ways to cut metal and maintain all your milling tools.

Create useful and essential items that can''t be purchased commercially, from an auxiliary workbench and tap holders to distance and height gauges, a lathe backstop, faceplate clamps, and so much more. 16 Metalworking Workshop Projects for Home Machinists contains a collection of unique projects based on the author''s most popular articles that have been published in Model Engineer''s Workshop magazine. Every satisfying project is intended to make workshop tasks easier once the item is completed and ready for use. Author Harold Hall was the editor of Model Engineers'' Workshop magazine and established himself as a mentor to Tyro model engineers worldwide. He is also the author of seven books in the indispensable Home Machinists Series.

A skill that consists of precisely spacing cuts, dividing is a crucial technique for gear cutting and radial work on a metalworking lathe. This complete guide to dividing clearly explains its principles  and covers everything a model engineer needs to know about dividing and several methods that can be achieved – from simple applications without specialized equipment to the use of a semi-universal dividing head and a rotary table. The mathematics of dividing are also included and written in an easy-to-understand format that won''t intimidate. Author Harold Hall was the editor of Model Engineers'' Workshop magazine and established himself as a mentor to Tyro model engineers worldwide. He is also the author of seven books in the indispensable Home Machinists Series.

Through the pages of Model Engineers' Workshop magazine, author Harold Hall, has established a reputation for introducing the tyro model engineer to a wide range of machine tool operations. In this book he introduces the milling machine. This book assumes no previous experience of using the milling machine and through the medium of four minor and four major projects will lead prospective users of the milling machine through all of the techniques involved. Whilst the detailed descriptions in the book are aimed primarily at those wishing to extend their knowledge of milling, the projects will be of use to the experienced operator wishing to add to their workshop equipment. All of the projects are extensively illustrated and include full workshop drawings. Once followed through, the reader will have amassed a wealth of practical skills and added a number of useful items to his range of workshop equipment.

Faced with the prospect of machining a gear or gears for a project, many model engineers will be discouraged and will turn elsewhere for their next model. This need not be so, for the principles underlying gear cutting and many other aspects of engineering where an accurate division of circles is required are explained in depth in this book. Radial work on a metalworking lathe, such as the cutting of gearwheels or the drilling of holes on a set radius, calls for a method of precisely spacing the cuts. This skill is known as Dividing. The principles underlying this aspect of engineering are explained in depth in this book. It covers the subject of Dividing, dealing with the many methods that can be adopted: from simple applications without specialised equipment to the use of a semi-universal dividing head and a rotary table. The mathematical aspects of dividing are also covered but at a level that will be understood easily by a model engineer. Dividing equipment is relatively expensive, so two fully-detailed designs are included for dividing heads: a basic unit and the equivalent of a commercial semi-universal head.

This collection of eighteen unique projects for home workshop equipment enables the model engineer to create useful and even essential items that cannot be purchased commercially, including an auxiliary workbench, tap holders, distance and height gauges, a lathe back stop, a tailstock die-holder, faceplate clamps, collets, DTI accessories, sash clamps, low profile clamps and a tapping stand. Each project is designed to make the model engineer's task in hand easier than it would have been, had the items not been made. Each design is illustrated with good quality photographs and comprehensive working drawings. Author Harold Hall is a former editor of the enthusiasts' magazine Model Engineers' Workshop, within whose pages all of these projects were originally featured.

This book contains a comprehensive range of data, which is required in the metalworking workshop and by those designing a wide range of engineered items, tools and machines. It provides, in a single concise volume, data that is only otherwise available by reference to many different sources or more expensive publications. For those involved in restoration work, the book also includes details of items not now used, and for which data is not easy to locate. Harold Hall was, for a number of years, the editor of Model Engineers' Workshop magazine and is the author of four previous books in this indispensable series.

This book deals with the process of choosing and using a milling machine and its accessories. In addition to the machine itself, the accessories include the cutters, cutter chucks, workpiece clamps, vices, angle plates, dividing heads, rotary tables, boring heads and other minor items. The content is divided into three main sections. Firstly, it describes what machines and accessories are available and covering each one in detail. The author explains which are essential and which can be obtained when the workshop activity eventually demands one. There are also suggestions on how the equipment chosen should be installed. The usage of each machine and accessory is covered for all but their most complex uses. Typically, using the rotary table and the dividing head are both described to a detail sufficient for the majority of uses that will surface in the home workshop. The third section deals with the actual machining process, covering the choice of the cutter for the task in hand, the speeds to use and how the direction of the feed relative to the cutter rotation is vitally important. A less-understood feature of milling, back cutting, is also explained.The subject of sharpening milling tools is briefly covered and a simple off hand grinder fixture that will bring new life to a used end mill is described.
