THE COMPACT LATHE

By Stan Bray  187 pages
This book deals with the  introduction in the late 1970s the belt-drive 105 mm x 450 mm (4" x 16") Austrian-built Emco Compact 8 caused quite a stir. Here was a neat, compact, modern-looking machine with angular lines, chrome-plated controls and a bright yellow paint finish in a shade even more startling than the contemporary General Motors Pulsating Primrose. Built to a strict standard of accuracy - DIN8606 - the lathe featured a self-contained motor-drive system with a built-in reversing switch and proved an immediate hit in Europe and America.
Unfortunately, all was not as rosy as it first seemed for the lathe lacked a tumble-reverse mechanism - so making repeated boring operations and left-hand screw-cutting difficult - only 6 change-wheels were provided (though these were sufficient to provide a fine feed to the carriage) and there was no proper back gear, just a speed reduction through a toothed belt to a second pulley assembly. The omission of back gear was a considerable drawback for, with a bottom speed of 100 r.p.m., both screw cutting and the turning of large diameters was made more difficult for beginners. Some higher-speed versions were also manufactured and fitted with a pulley set that gave a bottom speed 200 r.p.m. together with a top of over 3000 r.p.m. While ideal for smaller work these models, which are very rare, are best avoided for model-engineering purposes. Using a 0.5 h.p. 1375 r.p.m. 1-phase motor the normal speed range was: 100, 250, 350, 500, 850 and 1700 r.p.m.
