　　SHERLINE MODELS 1000/1100 and 4000/4100— Designed by Harold Clisby in Australia in the lathe 1960's, the Sherline lathe took advantage of the stiffness and economy of aluminum extrusions to eliminate the flexibility problems of the then-popular Unimat. Also sized at 3.5" x 8", it took aim directly at Unimat's market. It offered a good line of accessories including a thread cutting attachment with metal gears, chucks, steady rest and several tool posts. Mr. Clisby was a prolific inventor, and turned his attention to a successful air compressor design, turning over the manufacture of the lathe to Ron Sher of Sher Pty. Ltd. in Australia. Joe Martin became the first US importer of the lathe, when it was sold under the Craftsman label by Sears and also under the Sherline label. It was also sold under several other brand names such as Brookstone, Jensen and NatCam (National Camera) until the Sherline name became well known on its own. The original several hundred imports were a metallic blue color with brass bed and table and a small motor facing toward the right. The second photo shows early packaging where the box had its own carrying handle. After production moved to the USA, the finish changed to black and the AC/DC motors (now facing to the left) increased in power from 1/5 HP, to 1/4 HP, to 1/2 HP eventually to be replaced by a far superior DC motor that provides even more torque. Sherline machines are still in production and can now be purchased with all the modern features available on large machines like digital readouts and CNC controls. A longer lathe with 17" between centers is also available. The last photo shows a current production Model 4000 A lathe with chucks. The current price of $575.00 is actually less expensive in today's dollars than the original Unimat was at $99.00 in 1953, and use of CNC factory machining makes today's tools far more precise and accurate. Sherline also offers a line of three similarly sized milling machines. Though Unimat offered a milling column for the lathe, a stand-alone milling machine was not available in this size until Sherline introduced it.

　　SOUTH BEND 9" MODEL C WORKSHOP LATHE— At over 4 feet long, this lathe pushes the limits of the criteria for our miniature machine tool collection; however, South Bend lathes have been and are still so popular world wide that we felt no collection would be complete without one. The 9" Model C dating from a 1935 design is probably the definitive South Bend lathe.

　　Machine tool expert Tony Griffiths says, "Exported world-wide, the beautifully made classic American South Bend 9-inch "Workshop" lathe still has an enthusiastic following. Amazingly, the design, developed and refined, but still to its essentially original appearance and dimensions, is included in South Bend’s catalogues of today as a 10-inch lathe—a production run of over 69 years. During WWII many South Bend lathes of all sizes were exported to the UK under the "Lend-Lease" scheme, and thousands are still in amateur hands giving faithful service. High-quality materials were always a feature of these lathes—even the screws holding the gear guard covers were hardened so that repeated removal for cleaning and lubrication did not burr their slots and so mar the lathe’s appearance. The headstock spindle and bearings were masterpieces of precision engineering and, given just a modicum of lubrication, the hardened spindle and cast iron bearings of the 8-inch Junior and "9-inch Workshop" models, (an ideal combination of materials, incidentally) appear to last almost forever."

　　It's popularity is such that many "clones" of the South Bend design have been manufactured by other companies over the years.

　　STARRETT SQUARE and BROWN & SHARP ANGLE GAUGE— The small 4" LS Starrett machinist's square will get regular use in our shop rather than languish in the display cabinet. In addition to the standard square arm, a center finding arm is also included.

　　The tiny Brown & Sharp angle gauge is the smallest we have seen. The arms are only about 1" long, but it is perfectly functional. Most modelmakers would find this an extremely useful tool, although we doubt it is still offered for sale by B&S. (A quarter is used for size illustration.)

　　Both tools donated by Phil Gerrard, who also donated many small drill bits, a custom boring head and other tools for use in the Foundation machine shop.

　　TAIG LATHE— One of the few other small machine tools produced in the USA, the Taig is made in Arizona. Like the Sherline, it is also based on about the same size as the old Unimat. The tailstock uses a quill feed for rapid drilling (but without micrometer control) and the headstock has T-slots in the extrusion for mounting fixtures or indicators. To keep costs down, the basic lathe is available with or without a motor. Taig also makes a milling machine.

　　TOYO LATHE— For many years the Toyo Lathe was Japan's answer to the Unimat. Sized about the same and of similar layout it was recognizable by its bright green color. Our example has both a 3-jaw and 4-jaw chuck. Inside the swing-out pulley cover are two pairs of 3-position pulleys offering six speeds using the two-position belt from the drive motor. Two separate speed charts are listed inside depending on whether you were using 50 or 60 Hz current. A separate belt could also be used to power the feed screw and a threading chart was posted inside the cover as well. For a time this lathe was marketed as the Sakai lathe, but distribution ceased when the company founder died.

　　UNMAT 1 LATHE SYSTEM— The last of the small machines to remain in production carrying the Unimat name is made entirely from plastic except for the extruded aluminum bed and the pot metal chuck. Though limited to cutting wax, wood and perhaps a little aluminum, the system incorporates several clever design features that allow the components to be put together in many ways to do a lot of different jobs. There are optional modules available for milling, drilling and rotary work as well. There are a number of packages at various price levels that incorporate different modules. A DVD and book of projects comes with the machine, which is sold and promoted world-wide. (The book is in six languages.) While still manufactured in Austria, the Unimat is no longer made by Emco as was the case with the older metal machines up to the Unimat 3. (The Unimat 4 was made in Taiwan.) Now made by Manfred Heindl and The CoolTool Company in Austria, the Unimat name continues in a brightly colored, fun, multi-purpose tool system that is well supported with accessories and features, but is suitable for light duty work only. According to the box cover, the machine has won several awards for design.

　　Photo 1 shows the cover of the box of the "Classic" 6-in-one set. The various configurations are shown in the cover photo. Photo 2 shows the components as packaged in the box. Photo 3 shows a detail of the pot metal 3-jaw chuck, which is 1-7/8" in diameter and one of the few metal parts supplied. (Even the collets are molded from plastic.) The final photo shows one of the best features of the system; that is, it is extremely well documented with manuals, project books, a video and a DVD. The Unimat line takes advantage of all the marketing tools available to a modern manufacturer, keeping in mind it will be sold alongside colorful kits and toys in the hobby market.

　　The last photo shows our 6-in-one set configured as a metal cutting lathe. A One Euro and American Quarter dollar coin are shown on the crosslide for size reference.

　　UNIMAT DB200/SL1000— Introduced in 1954 and selling for $99.00 in the wooden box, this small tabletop lathe was an instant hit that revolutionized the home lathe market. This Austrian-made tool offered a huge line of accessories and many thousands were sold. It's weakness was its flexibility due to the use of a bed made from two round rods. It is still popular with tool collectors today, although for your money you can buy a modern lathe that is in current production that will make more accurate parts. This is the one that started it all, though, and its 3.5" x 8" size was the basis of the design of many of the lathes still sold today. Sitting in the top of the box is an optional saw table attachment, one of many options available for the machine.

　　UNIMAT 3 LATHE— The last Unimat to be produced in Austria, it solved the bed flex problem by going to a cast, dovetailed bed. The light duty motor limits its usability, but the large line of Unimat accessories kept it popular for a long time. Manufactured in Austria by EMCO, it was eventually replaced by the Unimat 4 which was manufactured in Taiwan, and the drop in quality turned off many former customers. It is no longer distributed in the USA.

　　WADE CAV LATHE #2— The Wade CAV was manufactured by CAV Small Tools Ltd., in Sussex England from 1922 to the lathe 1930's. It is made using polished pressure die cast copper-aluminum alloy components. Keep in mind that aluminum was considered almost a precious metal in the 1920's, so this was a pretty radical choice of materials for the time. It also has a back gear for screw cutting and a steel bed instead of the usual cast iron used at the time. This example has a 3" 3-jaw chuck. The bed itself is a large tube, which is in itself unusual.

　　This nicely polished lathe was generously donated to the Joe Martin Foundation by Gary Twemlow, Scotland.

　　WOLF JAHN & CO. —Made in Germany, this lathe is very similar to the one above but is not accompanied by the second pulley shaft. Instead of on the tool rest slide as on the lathe above, the company name is stamped into the front face of the headstock. (See photo 3.) This lathe also shares the pulley with index holes which can be seen in the second photo.

　　UNKNOWN BRAND JEWELER'S LATHE —There is no manufacturer information anywhere on this donated lathe, although it is a very attractive design with the polished brass parts and black-painted bed. The brass legs give this tiny machine (the bed is 12-5/8" long) the look of a larger lathe. The roughly cast bed has two triangular pointed ground ways that register in grooves in the bottom of the headstock, tailstock and slide. Each is positioned by loosening a large brass thumbscrew under the bed, although one thumbscrew has been lost and replaced by a bolt on this particular machine. The capacity is a swing of 1-5/8" (3-1/4" diameter) by about 6" between centers. The headstock does not actually have a center or an internal taper for one, but rather a threaded end on the spindle shaft is used to accept the chuck which can hold a center. A white celluloid plastic handwheel with brass spokes operates the tailstock and is marked, "Celluloid, PAT. May 14, '78." which presumably indicates 1878.
