Excerpt from Screws and Screw-Making: With a Chapter on the Milling Machine Small screws - by which we mean those under Jin. diameter - are not comprehended by the Whitworth nor the Sellers systems. These small screws, which are chiefly employed in horological mechanism, were taken in hand by the Geneva Society of Arts, and a remarkably thorough system was tabulated by Professor Thury, which is now adopted in the horological trades on the Continent. On the recommendation of a committee of the British Association for the Advancement of Science, Professor Thury's system has been adopted in the United Kingdom. We have printed all these reports unabridged, and their perusal will explain all that has been done in the way of theorising on screws. The table of wheel trains to cut various thread-rates by the aid of guide-screws, extends further than any one we have met with. It includes nearly 1,000 thread-rates, ranging from the coarseness of one turn in sixteen inches to the fineness of one hundred turns per- inch. In the practical part we have endeavoured to give a clear and concise explanation of the methods and processes of screw-making. Many illustrations are shown of the most important machinery used for the purpose, which we are continually making. With every confidence that this treatise supplies a want hitherto not fully met, we offer it to all who are interested in mechanism of which screws form an integral part. We shall be at all times willing to correspond with any reader who may require information not given, and shall be glad to hear of any error in figures that, even with the greatest care, may have remained undetected in the tables, so that correction can be made in a future edition.

Learn what a screw thread is and how it functions. Part One covers the techniques for cutting threads in wood, including a lathe, using jigs and hand-held cutters and cutting them by hand. Part Two puts these techniques into practice with projects that include wooden bolts, threaded spindles, a screw top box, screw off tops for cruet sets and walking stick joints.

Are you tired of waiting for the men you like to ask you out? Do you think waiting for the guy to make the first move is outdated and lame? If you’ve answered “yes,” Screw Cupid is just the book for you. Screw Cupid is the guide for every woman ready to take her dating life into her own hands. Samantha Scholfield has many years of dating experience, and the techniques and strategies she reveals here were developed via extensive trial and error—and by consulting and collaborating with hundreds of women (and many men), and by refining the best of the extensive pickup advice that already circulates among men. The result: perfectly calibrated guidance on how to initiate a conversation—anytime, anywhere—and get right to a date, all without a guy knowing he’s being picked up.
