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.

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.

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.

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.

An essential resource for anyone working against terrorism in any form it may take! Written for threat assessment professionals in the post-9/11 era, this timely book will help you understand the motivation to commit acts of terror, the thinking patterns common to many terrorists, the psychology of Muslim fundamentalists, methods for predicting the likelihood of chemical/biological attacks, and a great deal more. You'll learn about hostage/barricade situations and the role of the crisis negotiator, including victim/perpetrator psychology and factors that indicate progress is being made in a crisis negotiation and factors that imply imminent lethality. After reading Terrorism: Strategies for Intervention, you'll have a better understanding of: biological, social, and psychological constructs that are important to understanding group violence the role of emotions in violence the history of chemical/biological weapons use from 1978 to the present, and methods of predicting the likelihood and origins of such attacks the importance of concurrent sequences in relation to chemical/biological attacks hostage/barricade situations, the makeup of crisis negotiation teams, and the role of the crisis negotiator hostage incident databaseswhere to find them, what they contain, and how they can be used effectively six different types of hostage takers and what strategies have the best chance of bringing each type's crises to an end factors that indicate progress is being made in a crisis negotiation and factors that imply imminent lethality ethical concerns for forensic consultants when dealing with the issues surrounding terrorism Here is a sample of what you'll find in this informative and well-referenced book: Terrorism as Group Violence illustrates the complexity of terrorism and the need to consider the interplay of biological, social, and psychological influences on terrorist behavior. This chapter identifies the constructs and data generated by theories of violence that are relevant to terrorism. Next, profiles of terrorists' motivations are scrutinized, followed by a probing of the specific patterns of thinking salient to their motivations. Finally, approaches to solving the terrorist problem are framed. Five handy tables make important points easy to access and understand. Chemical and Biological Violence: Predictive Patterns in State and Terrorist Behavior is essential reading for any serious evaluator of chemical and biological weapons. This chapter uses the Lethal Violence Sequence as a means to help predict chemical/biological weapons use by religious and ethno-nationalist terrorist groups. It includes case vignettes, data categories that can help make predictions more accurate, and a discussion of solutions for use by individuals, law enforcement and federal anti-terrorist agencies, as well as manufacturers and other industry entities, plus a consideration of government and international efforts. Negotiating Crises: The Evolution of Hostage/Barricade Crisis Negotiations examines multiple ways by which a crisis incident can be classified, analyzes the results of hostage incident databases, discusses negotiation techniques, and explores the impact of captivity on the victim. The author reveals important characteristics of hostage/barricade situations that can be vital to the success of the evaluator/negotiator. Six informative tables in this section make statistics and procedures easy to understand. Ethical Concerns in Forensic Consultation Regarding National Safety and Security provides an essential overview of the ethical challenges that mental health professionals and behavioral scientists face when they consult on matters of national security and safety. This chapter delivers useful guidance for professionals who

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 collection of 18 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 then it would have been had the items not been made.

When Harold Hall was Editor of Model Engineer's Workshop magazine, he was surprised by how just so many of his readers had no access to a workshop at home, or even at college. This book presents a complete guide to building or converting a workshop space and then equipping it to serve a wide range of metalworking activities including model engineering, model making, car restoration and clockmaking. It explains all the essential requirements of the workshop environment: planning, heating and lighting, condensation plus health and safety factors. It then explains in detail the choice of various tools and equipment for differing tasks so the new workshop owner can avoid making unwise purchases. The book is based on a very popular series of articles which originally appeared in the pages of Model Engineers' Workshop magazine, and which have been revised for publication in this edition.
