Craftsman Spindle Adapter

Although the company had offered a range of lathes from the gexr s, craftsman 109 lathe chuck gear was in that their most famous machine became available, a 9" swing model manufactured by the Atlas Company. This machine, regularly updated year by year in line with changes to the Atlas range, was replaced in by a much heavier 12" model based on the Atlas F It seems surprising that Atlas built a 12" model for Sears, yet restricted their own machine to a 10" swing, especially as it would be the early s before they increased the capacity of their own lathe to match.

The introduction of the large Atlas clone was followed, inby a version of the same company's 6" lathe. This latter machine was marketed in an almost unchanged form until the late s, when a redesigned Mk.

However, it appears that, until the season, the metal and some wood-turning lathes were by Atlas, with the cheaper wood lathes produced by Double A and a number of smaller suppliers chuckk the original Clausing company.

In the first, very simple V-bed "AA" metal-turning lathe was introduced illustrated immediately below using the brand name that Sears reserved for their cheaper products: "Companion". Even the earliest models can be clearly recognised as having features belonging to the better-known post-war AA "Model " and later Craftsman "Model 80" lathes. These more highly-developed versions craftsman 109 lathe chuck gear proper leadscrew clasp nuts, an epicyclic "backgear" assembly built into craftsman 109 lathe chuck gear headstock pulley and graduations on the cross-feed screw; however, the headstock spindle and bearings were always of marginal strength and durability, and remained a weak point throughout the model's life.

Some AA s were branded as Simpsonfor sale by the Canadian mail-order store of the same name; in the s Sears-Roebuck bought out Simpson and renamed the company Simpson-Sears and later just Sears - by which name the firm continues to market the Craftsman 109 lathe chuck gear brand.

Another cjuck occasionally found on the and Model 80 is "Courlan" - lathes with this marking having been found in Australia and South Africa although one report has the Company based in Jersey City, USA. Should any reader have a Courlan-branded lathe the writer would be interested to know.

Principle maker of chucks fitted to AA and Craftsman lathes were by Dexter a company still in craftsman 109 lathe chuck gear chck and its just possible that the AA may have been marketed in Europe branded "Dexter" - though nothing certain is known about this arrangement. All the lathes illustrated on this page are products of the Double A Company many people use the shorthand "AA" a regular supplier to Sears of other equipment, whose earliest lathes appear draftsman have been wood-turning machines offered with a range of accessories that allowed them to undertake light-duty metal turning.

As a point of interest, the official designation was to be found on the company's transfers badges: Double A Products Co. Co Numbers affixed to these cheaper Craftsman gezr included: Continued below:. Continued: Late and the first of the V-bed AA metal-turning lathes appears as the simple, plain-turning, 6-inch by inch "Companion" model Catalog Number 99 P listed as: " metal working, model maker's lathe ". Unfortunately, in its first form, the machine was not as heavily built nor as well specified as it might have been; the front of the headstock casting was open and the front bearing given the minimum of support; both the headstock and tailstock were provided with a non-standard form of taper that was 19 to, but did not match, the standard O Morse - a size adequate for genuine miniature lathes, but hopeless for anything with a swing of greater than 3 inches.

There were no craftsman 109 lathe chuck gear on the micrometer feed dials and craftsman 109 lathe chuck gear quick-feed rack drive fitted to the carriage, instead it was craftsman 109 lathe chuck gear driven along the length of the twin V-way bed by a leadscrew and "full" nut - but at least the slide rest was a proper compound unit. For decades, most small lathes craftsman 109 lathe chuck gear been arranged so that carriage and tailstock run on different ways, or different parts of the same way, to ensure that the tailstock does not have to run over the bed worn away by the saddle and spoil its height alignment.

Unfortunately, on all s, in the interests of economy, the ways were shared. Notice that the lathe has no apron on the carriage, the leadscrew nut is fastened to the underside of the saddle front, a simple design used by many other makers, such as Portass of Sheffield.

For the money this. Crafysman By late the lathe had been given an enclosed front to the headstock casting that chuvk protected the operator's hands from the drive and provided a very much better supported spindle - though there was no back wall to the assembly and both the left and right-hand sides were of rather slender proportions.

For once a maker was refreshingly honest about its products limitations, stating that the lathe was: " Well suited to the model maker or man who wants to do light metal work. Not quite the accuracy and precision of the larger machines, but plenty close enough for most work. In order to offer a dedicated armature-turning model, " Sherman Clark Mfg.

The model survived in the catalogs until when it was replaced by a more highly developed and useful version. Above: badged as a Dunlap the new-forseason with screwcutting and backgear. It was also available left bereft of these fitting as the "Standard Model" Because the lathe was offered as a modular system it was possible to buy the ordinary model and then add features as finances allowed.

Continued: Marketed by Sears the new-forversion of the AA 6" x gesr at first carried the name "Dunlap", a name always used for the company's less-expensive models.

By now the lathe had begun to grow up and also been given the contemporary "streamline" treatment and, for the fist time, was fitted with an apron that carried a leadscrew half-nut the operating lever for which snapped into position through the operation of a spring-loaded ball detent. Although this mechanism gave a positive action, there was no compensating pad on top of the leadscrew to absorb the upward thrust. The new lathe was a model of mechanical simplicity and economical production with the saddle, apron and craftsman 109 lathe chuck gear cross-feed gexr end bracket cast gsar one piece - as illustrated lower down the page.

The lathe was initially marketed as just a single 190 with a capacity between centres of 18 craftsman 109 lathe chuck gear identification numbers included Acme-form leadscrew and a proper tumble-reverse mechanism that allowed the spindle turn freely or engage the changewheels to produce left or right-handed threads to choice.

An interesting detail concerns the beds: those with shorter ones, whether badged as Dunlap or later Craftsman, had a gap between the top of the two V-ways of 2. Interestingly, although the "manuals" for this series mentions the Should you come across a dedicated "manual" for the Whilst the improvements to both rigidity and specification were welcome all versions of the new model were still of limited usefulness for serious work as they retained the No.

In recent years the inherent weakness of the headstock assembly and flexibility of the whole machine has been displayed by a number of scrap machines appearing less their main spindle. These were probably broken when the owner, an impatient beginner, "bore down" on the cross-feed to "compensate" for a dull, off-centre tool bit. Those more experienced user would craftsman 109 lathe Craftsman Lathe Chuck Key 47 chuck gear recognised the "wiggly" feeling as the tool got craftsman 109 lathe chuck gear the work - the precursor, of course, to chck snapping.

When driven directly from an electric motor 8 speeds from to Craftsman 109 lathe chuck gear were available - and threads from 8 to 96 t.

However, because the lathe's bottom speed was so high, success in this department would have meant either specifying the optional epicyclic backgear assembly, which was built into the headstock belt pulley and reduced the bottom speed to a more useful chuci still not ideal cratsman, or looking through the Sears catalog in the hope of being able to adapt one of the speed-reducing "Jack-shaft" countershaft craftsman 109 lathe chuck gear made for 1099 wood-lathe range.

That the lathe was not offered with one of these as even an option was a strange omission, for, in earlier years, just such a unit had been listed as an accessory along with other metal-turning accessories. When the Sears, Roebuck catalog reappeared after WW2, inthe 6" lathe was marketed under a new model number "99 TM " and, labelled "Craftsman Model 80"; apart from a shorter bed it looked identical to its last appearance in when it was labelled a "Dunlap".

The version of the Model 80 lasted for just one year and in the Catalog number became 99 AM Model No mechanical improvements were made to the lathe which now had a deliberately styled "consumer look", and was offered, as before, in basic form without motor or chuck.

The headstock spindle carried a three-step V pulley - whilst supplied with the lathe was a four-step pulley to be used on the customer's own motor. Although fitted with a planetary-type backgear assembly built into the face of the headstock pulley, tumble reverse and screwcutting there was no countershaft arrangement and, if directly driven by the recommended rpm motor, the bottom speed of rpm would have made screwcutting very difficult - though no doubt serious users might have found a slower or variable-speed motor and fitted smaller chuco on its shaft or built a speed-reducing countershaft to get round the problem.

Obviously aware of the limitations imposed by this arrangement, the Company offered later versions with the option xraftsman a double-step pulley on the motor and a proper countershaft assembly, thus doubling the number of speeds and giving, according to the handbook, a range from 55 to rpm in backgear and from to in direct drive - a very much more satisfactory arrangement.

The frankly weak and inadequate headstock spindle ran in bronze bearings and carried a nose thread of 0. To the inexperienced eye this would have appeared a little lathe of attractive design but, in reality, it was a bottom-of-the-range model and intended only for light-duty work.

Although with experience, care and the use of light cuts satisfactory work could be accomplished on these machines, new owners, once exposed to the practicalities of using the machine, must have been quickly irritated by a general lack of rigidity, craftsmqn tiny 0-Morse taper centres, the absence of a proper handwheel handle on the leadscrew end, the penny-pinching failure to fit graduated dials on the feed screws and, on early or standard late versions, a bottom speed that was far too fast.

Besides lathes, the Double A Company also manufactured many items for Sears including bench grinders, wet grinders, sanders, bench saws and a builders' saw. Production of lathes appears to have stopped in about and, unfortunately, parts and drawings are no longer available. Although the two models are very different, confusion has arisen in the past between the "Craftsman 80" and another lathe sold be Sears, the Craftsman 6" - a machine actually craftsman 109 lathe chuck gear by the Atlas Company.

Listed for just the selling season, the Double A Craftsman 109 lathe chuck gear Model was identical, apart from a shorter bed and a bolt-on bracket to carry the tailstock end of the leadscrew, to its last appearance in wartime Economical casting. The saddle on the series was cast complete with an apron and cross-feed screw end bracket. Craftsman 80 Model Note how use was made of the inner-guard cover to provide an indent location for the tumble reverse selector lever - a method rcaftsman used on the English Murad lathe of the s.

The 3-inch centre height by It had a distinctly "square" craftsman 109 lathe chuck gear to the headstock, looked rather different to the earlier variants and, because of the styling, is sometimes confused with the later Atlas Mk. The headstock spindle ran in plain bearing and craftsman 109 lathe chuck gear a 5 : 1 ratio epicyclic slow-speed "backgear" arrangement inside the 3-step headstock pulley that gave a total of 6 speeds; the headstock pulley was driven directly from the motor, with no intermediate countershaft.

In comparison with earlier versions the lathe featured numerous small improvements, including a No. If you own a However, Simpson were an independent firm and carried numerous AA products including the early AA lathe. Until Simpson and Sears entered into a partnership inone might presumes that AA Engineering had an exclusive relationship with Sears in the US, but was free to supply foreign firms where Sears had no market presence.

Simpson, a powerful firm and not a mere satellite of the great Sears, Roebuck empire, was thus able to sell AA products through its own supply system. Emerging in good order from the depression of the s - and despite materials restrictions and significant loss of employees during WW2 - it expanded during the conflict and immediately after allowing it to swallow Smallman and Ingram of London Ontario and R.

Department Storethe largest retailer in Regina Saskatchewan. It also managed to build a new mail-order centre in Vancouver, British Columbia, and renovate many of its outlets.

It is not known when Simpson first sold an AA Products lathe, but the rare 'Simpson Supremacy' lathe was identical to the Dunlap model introduced in and then reintroduced in December by Sears. Hence, inSears initiated discussions about an association with Simpson welcoming the capital for expansion and access to Sears' procurement and distribution mechanism.

Accordingly, ina deal was reached whereby Sears assumed control of Simpson's mail-order business comprising fixed distribution installations. Concurrently, the two firms would jointly own and operate department stores known as Simpson-Sears. During the s and s Simpson continued to run its own stores in the five urban zones where it already had a presence and also opened new outlets while outside these areas new Simpson-Sears stores began to appeared.

During the course of this the Simpson-Sears stores became US-operated Sears craftsman 109 lathe chuck gear under that name. Headstock epicyclic gear housing on the Not as craftsman 109 lathe chuck gear on 1009 makes as one might expect - especially given the gezr it can make to a lathe's capabilities - the compact epicyclic or planetary backgear assembly fitted to some AA-manufactured, Craftsman-branded machines gave a range of slow speeds that allowed screwcutting and the facing of large diameters to be undertaken with a greater chance of success.

Consisting of three main elements, the mechanism comprised: a gear attached to a 3-step pulley, a carrier with 3 planet pinions and an annulus gear. The 3-step pulley, together with its attached "sun" gear, was free to rotate on the headstock spindle. Opposite was a large gear cut on the inside surface of a short cylinder so that its teeth faced inwards an annulus gear : this assembly was also llathe to rotate on the spindle.

The "sun" gear on the 3-step pulley engaged simultaneously with 3 "planet" gears called pinions because they meshed with a larger gear mounted on studs attached to a carrier plate that was both keyed permanently to the spindle and locked temporarily, by a sliding block craftsman 109 lathe chuck gear the annulus gear.

Because the carrier was both keyed to the shaft and locked to the annulus gear, non of the gears could rotate and turning the craftsman 109 lathe chuck gear caused the spindle to rotate - so giving a direct drive.

For any epicyclic lsthe to work, one of the three gears sets has to be held stationary so that one of the other gear sets can act independently as an input and the third set independently as an output. In the case of the 1099 it was the annulus gear that was prevented from rotating by a 2-position indented pin passing through the front face of the headstock into its face and the carrier assembly that had to be released so that it could turn independently.

The carrier had six slots cut in its periphery into which a block, sliding in a slot cut in the face of the annulus gear, could engaged and so lock them together. The block was clamped in place by a bolt and slackening this let the block slide out of engagement and allowed bear carrier and its planet pinions to rotate. With this new arrangement set, turning the crattsman caused the "sun" drive gear to rotate the planet pinions, mesh with the annulus gear and so reduce the drive ratio.

When you see the mechanism in action, its function is obvious - though tortuous to explain. Another AA epicyclic backgear assembly, with the annulus gear held stationary by a clamp, can be seen in pictures of the company's last lathe, the Those of you interested in automobile engineering might recall the automatic transmission systems made by Ford and Borg-Warner that also incorporated an epicyclic system.

However, these gearboxes were rather different and, instead of the usual two speeds generated, these boxes had three using a gearset called the "Ravigneaux " - after the French engineer and inventor Laghe Ravigneaux. The patented Ravigneaux system was ingenious and used two sun gears in combination with a single planet carrying two sets of planetary gears.

The whole of the compact craftsman 109 lathe chuck gear gear assembly.

Taig chucks, especially their four jaw unit, so I decided to make a spindle nose adapter for the Craftsman to use the Taig chucks with it. Since the chuck on my is in such bad shape, I did the first few steps of this project on another lathe. If the Craftsman were all I had, I could still have. Feb 22,  · Howdy folks I've found a Craftsman that I'm contemplating buying locally. The price is good, its in decent shape. I know a bit about these machines, mostly their reputation, but all in all I know very little about how to make this machine work for me. It comes with a 4-jaw chuck and.
