　　MANSON 1.5" x 4" LATHE— Manufactured in Los Angeles by ManSon Small Machines in the 1940's, this small lathe causes some arguments as to whether it is a real lathe or a toy. 曼森1.5 “ × 4 ”车床制造在美国洛杉矶由曼森，小型机器，在1940年的，这个小车床的原因，一些论据至于是否是一个真正的车床或一个玩具。 At the time it was billed as "The World's Smallest Lathe."在当时是由被称为“世界上最小的车床” 。 Overall length is only 9-3/16". The extremely tiny size limits the parts that can be made on it, but the design is substantial enough to indicate it was intended to make small metal parts to some level of accuracy. The original finish was grey paint. The spindle has a 3/16" through hole and threaded nose (7/16-20) to accept a faceplate or chuck.总长度只有9-3/16 “ 。极其微小的大小限制的部分，可以向它提出的，但设计相当可观，足以表明它的意图是为了使小金属零件，以某种程度的准确性。原来完成是灰色油漆。主轴已3 / 16 “通过孔和螺纹鼻子（ 7/16-20 ）接受一个面板或夹头。 The swing over the bed was approximately 2" with 4" between centers.摆动超过床上，大约是2 “ 4 ”之间的中心。 Swing over the carriage was 3/4" and collet capacity was 1/8".摆动超过运输是3 / 4 “和collet能力，是1 / 8 ” 。 The carriage was driven by a rack gear by means of a handwheel on the carriage.运输是由机架齿轮透过一个手就运输。 The tool post accepts a square 3/16" cutting tool. An accessory kit was available that included a 4-jaw independent chuck, faceplate, drive togs and collets. An early advertisement shows the price for the basic lathe as $39.75, with $41.50 being the price for a lathe with a drive dog, tool bit and test rod. An adjustable tailstock was available for an additional $10.00 and a more powerful universal motor could be added for an extra $25.00. These small lathes have become highly collectible and now sell for10 to 20 times their original cost or more.

　　MASTER 3" x 4" LATHE "BBW"— Similar in design to the Manson Lathe above but manufactured by a later company called the MasterSon Company starting in 1949, this lathe has a polished aluminum finish instead of paint. The spindle has a taper for a WW collet. Included is a combination dead center/1" faceplate that has a groove in it to act as a drive dog. The 3" swing over the bed is larger than the ManSon, although it uses the same carriage assembly but with a taller tool post. Unlike the 3/16" cutting tool on the ManSon, the Master lathe uses a 1/8" square cutting tool. The tailstock is similar to the ManSon, but it is released for movement with a lever on the front face of the tailstock body rather than the over-the-top lever used on the ManSon. It is driven by an O-ring belt to a one-speed, one-direction motor housed inside the cast base. Unlike the ManSon which drove the spindle directly with an O-ring belt on a two-speed pulley offering 350 or 700 RPM., The Master BBW drives the spindle through a set of brass gears. The spindle runs in ball bearings rather than the plain bronze bearings used on the less expensive models. No name information is cast in as was the case on the older Manson lathes. The main body casting is very similar to the ManSon except the headstock is raised to accommodate a 3" swing. The belt cover on the left end of the machine snaps off rather than being held on with screws as on the ManSon. This lathe retailed at the top of their product line at $129.50. A set of back gears for threading was available.

　　Specifications are listed as: Length: 10.5", Width: 3.75" and Height: 7.25". Shipping weight is 12 pounds.

　　Master Lathe and accessory kits. MASTER LATHE "S"— The "standard" version of the master lathe features a spindle that has an external thread to accept a chuck and a hole through the spindle of 3/16", allowing it to accept bar stock up to 1/8" in diameter through the spindle. The spindle runs in porous, self-oiling bronze bearings designed to take both radial and thrust loads. It is finished in a gray paint and has the same dimensions and specifications as the BBW version, the only difference being the spindle designed to take a chuck rather than a WW collet. The lathe originally sold for $79.50. Like the BBW, this lathe takes 1/8" square cutting tools in the tool post. Like the BBW model, the lathe is identified by a yellow, red and black decal on the front of the machine.

　　This lathe was purchased with the extra 4-jaw chuck kit in a metal box. The kit includes the 4-jaw chuck, a faceplate, two drive dogs, a drill chuck, center countersink drill, tool bits a collet chuck and three collets and a hex key. This kit was listed as having an original price of $34.50. Also purchased with this lathe is the threading kit in the smaller red cardboard box with wood insert which sold for $12.50 originally. The kit includes several size threading dies and a pin vise type die holder.

　　MATTEL "POWER SHOP" wood turning lathe— This 4-way tool is essentially designed as a toy, but it can do some simple jobs. It can be set up as a lathe, disc sander, drill press or jigsaw. It has an extruded aluminum base, cast aluminum tailstock, sheet metal headstock with die cast ends and a die cast Handle and tool support that slides in a curved track on the extruded base. The spindle is a 1/8" shaft with a flat onto which a spur driver, sanding disc or simple drill holder can be pressed. The tailstock live center is simply a plastic part with a ball-shaped end that spins in a depression in the tailstock plate. The tailstock also acts as a stand when the machine is placed in the vertical position to be used as a drill press. There is an eccentric on the spindle shaft that drives the jigsaw. In the jigsaw configuration, the tailstock plate is removed and attached to the headstock to act as a table. Though quite simple in construction, it would actually be a fairly good introduction to power tools for a young craftsman. Included is an illustrated instruction book and even a simple plastic eye shield.

　　PATENT MODEL for a lathe (Unknown brand) —Prior to the use of 3D model software, all designs submitted to the patent office had to be accompanied by a working model to demonstrate the concept and function of the patented item. This small lathe is only 9" long and appears to be a model of a larger lathe rather than what was intended to be a functional, small lathe. For one, the handles on the handwheels are to scale and would not be sturdy enough for much actual use at this size. It is, however, beautifully built and has been well cared for. The base is actually cast, not machined from a billet of metal. With its belt driven headstock spindle, it goes back to a time when factories machines were powered by means of suspended leather belts driven by a line shaft that ran overhead (or in the floor). This was prior to the use of electric motors to power individual machines. All aspects of the lathe function and the 3-jaw chuck has working jaws. Other than stamped numbers for jaw position on the chuck, it has no maker's name or model number. Anyone knowing more about this lathe (model or full-size), please contact the Foundation.

　　RIVETT 504 LATHE— This 8" x 17" lathe was made by the Rivett Lathe and Grinder Co., Brighton, Boston, Mass, USA according to the label. It is fitted with a 4-1/8" 3-jaw chuck and a live center. The 3-position flat belt drive pulley has indexing holes drilled in the back. A 6" spoked handwheel could also be used to drive the headstock. The serial number stamped into the bottom of the tailstock casting is 3709.

　　RIVETT No. 2 watchmaker lathe from about 1896. This small lathe was benchtop mounted on a single post and features moveable headstock and tailstocks. In the middle is a positionable T-rest upon which the watchmaker rests his handheld "graver" to remove metal much like a woodworker uses a chisel tool on a lathe. The T-rest can be swung out of the way for loading parts or other hand operations. A small handwheel on the rear of the headstock spindle allows for hand indexing. The 3-position pulley was driven by a round pulley driven by an external motor. The bed of this machine is chrome plated steel rather than the usual cast iron, and all the serial numbers match.

　　SEL (Signaling Equipment LTD) Model 3080 lathe— Without a doubt the smallest lathe in the collection, this tiny English made lathe measures just 4-1/2" long and 1-3/16" wide at the base and 2-3/4" tall. It is molded from a hard, black plastic similar to bakelite and has metal pulley, centers, tool holder, cutting tool, crosslide leadscrew spindle center and knurled thumbscrews. It comes in its original yellow and black box which is in very good condition. The lathe itself is in perfect shape except that one half of one hold-down tine on the base is broken off. The photos show both a 1 Euro and quarter dollar coin for size reference. The Foundation also owns a small model machine shop that includes another lathe identical to this one plus a number of other miniature shop tools, all belt driven of a horizontal steam engine by Fleischmann. Not expected to actually be able to do any machining work, this model lathe was designed to add to the fun when creating a model of an old machine shop that used line shafts and overhead belts driven by steam or electric motors. The compound slide works in three directions, the cutting tool can be adjusted and the tailstock can be positioned and locked
