The lathe had its origins in the Denford Small Tools Company (D.S.T.), founded in Brighouse by one Horace Denford in the years before World War Two. The company's original products included a range of precision tools and inspection equipment - and, no doubt, sub-contract work for the many local general-engineering and machine-tool companies who once inhabited the area. It is believed that Denford moved at least part of their operation to a former spinning factory, Box Tree Mills, in Wheatley, Halifax during the closing years of WW2 (1939-45). The previous occupants had been a ship's telephone equipment manufacturer, Arthur Graham Ltd. http://psrcentre.org/userfiles/braun-paxette-super-iii-automatic-manual.xml

, who used the building between 1942 and 1944 after being bombed out of their Woolwich (London) premises. Nevertheless, demand in the UK was such that the factory hinted at a production run of over 400 units. Even today, in confirmation of these numbers, a small but regular supply of these well-made little machines turns up on the second-hand market. Other machine tools made included a useful little shaper (copied from a South Bend original ), a tool and cutter grinder (also sold under the Union and Harrison names) and a variable-speed vertical milling machine. Continued below: Details included are scant, just the main dimenions and specification and no hint of a Model Type or Series Nnumber. To date, the earliest catalogue found is a well-produced folder with a cream-coloured cover in card holding twelve sheets (secured with split pins) showing all three models, A, B and C, together with a range of accessories. Other catalogue covers can be seen here. By the 1970s Boxford had started to introduce a number of training-type CNC lathes and milling machines, a successful path that they follow to this day. In addition, a replacement for the original belt-driven 4.5-inch was announced, a geared-headstock model produced in various versions for both training and industrial use.Harrison eventually sold the Boxford concern, the last machine made under their ownership being Serial 284500 in early 1971. This lathe would, in the years to come, provide stiff competition for Boxford. The Company also widened their range of products to include wood lathes, tool-sharpening equipment, floor-standing double-ended grinders and polishers and a number of re-branded machines including pillar and bench drills, a drill-sharpening machine, a shaper (actually made by Realm Engineering of Croydon, Surrey and also sold as the Royal ) and a milling made by AEW. In 1962 Gerald Denford, the son of Horace, took over from his father and developed the move to CNC technology. http://hocikto.info/userfiles/braun-paxette-reflex-manual.xml


Even though the South Bend headstock, together with its spindle and plain bearings, had proved to be reliable and rugged (a South Bend bed always wears out before the headstock) Boxford used a much more rigid, box-like casting open only at the rear (to accommodate the drive belt) and carrying a spindle running in easily-changed taper roller bearings. Instead of locating the headstock on a front V and rear flat as South Bend had done, Boxford choose to use a V-way at both locations. However, in later years, with the development of under-driven versions (with a belt running down the front face of a now wider headstock) a change was forced back to the original layout. A further advantage was that the bearings could be replaced easily and, if required, much higher spindle speeds reached with reliability. Later models had ordinary bearings with 17 rollers and a shallower cone angle - and seemed to have worked just as well. Continued below: Collets, sized at C3, were carried in a hardened nose insert and retained by the usual sort of threaded draw-tube. Exactly when the gearbox and power cross-feed models were first made is uncertain, but they must have followed within a few months, for South Bend had been offering these versions since 1939 and the first known properly printed and illustrated advertising literature does show all three types. On the very first examples made the lathe was clamped to the stand or bench by two in-line bolts that passed upwards into each bed foot - the latter having been found cast in both cast aluminium and iron. The next version used three securing bolts, two being set across the bed and passing through a flange on the inner face of the (now exclusively cast-iron) foot and with the other on the foot's centre line passing through an inwards-facing boss. The final type, and found on most machines today, was a simpler arrangement of two bolts - one at the front and the other at the back of each foot. https://www.becompta.be/emploi/02-manual-wap-settings


When fitted with the optional 2-step pulleys on motor and countershaft, and combined with the 3-step cone (flat-belt) headstock pulley, these early versions had a usefully wide spread of spindle speeds (though bottom speed was too high) of approximately: 76, 140, 250, 390, 710 and 1300 in open belt drive and 40, 67, 120, 190, 350, 640 in backgear. The backgears, though often found damaged on used machines by mishandling, were robust enough to allow the lathe to be easily capable of turning the largest faceplate-mounted job. Both slides of the compound rest were driven by 10 t.p.i Acme-form (or 2.5-mm pitch) screws fitted with 1.6-inch diameter, satin-chrome zeroing micrometer dials - the friction setting of which could be adjusted (or locked) by a pair of by socket-headed screws that bore against spring-loaded balls. In January 1950 the flat-belt drive was abandoned, with lathe No. 1791 to become the first fitted with 4-step V-belt drive - a much-improved arrangement that gave a more useful bottom speed (ideal for screwcutting by beginners) and a total of 16 rather than 12 speeds. To convert a flat-belt machine to V-belt specification is simple - the pulleys interchange without any modifications being required. The standard V-belt speed range ran from 38 through 55, 87, 125, 75, 110, 175 and 250 r.p.m. in backgear and 200, 285, 450, 650, 400, 570, 900 and 1300 r.p.m. in direct (belt) drive. According to Work's literature seen by the writer, at the same time the tumble-reverse mechanism was altered: the inconvenient and slow-to-change bolted-up arrangement being replaced by a simple, quick-action, spring-loaded plunger design (though it's a fair bet that the change was not immediate and some lathes might have had the old parts fitted). http://www.eau-petit-pont.com/images/boxer-530x-manual.pdf


Made from welded steel plate, the new stand held the countershaft and motor assembly, the optional coolant tank and motor and provided, in its right-hand compartment, storage shelves with a collet tray fastened to the inside of the (locking) door. Belt tension was released by an external handle that protruded through the stand's left-hand face, a fitting that provided a strong temptation to use it as a clutch - a potentially dangerous undertaking. This weakness (from a safety point of view) was removed when the mechanism was redesigned and made accessible only by opening the door. However, the new models did not replace the old, but complimented them, the original rear-drive types remaining in the Boxford catalogue (optimistically, one would have imagined) until at least 1977. With the introduction of the Under-drive models came a superior cosmetic finish with the castings carefully fettled, filled with cellulose knifing putty, rubbed down by hand and spray painted. While not to the standard of the very much more expensive Raglan lathe, with its use of special Trimite paints, this new finish (generally in a grey cellulose to BS692 sprayed over a filler) was a considerable improvement over the earlier lathes, the first of which had, to be blunt, a decidedly utilitarian appearance. Although the rear-drive models suffered from a very deep countershaft, and consequently took up a good deal of room, the under-drive versions were very compact - with a bare stand only 17 inches front to back - and today are consequently by far the more popular buy second-hand. From December 1973 - approximately Serial No. 33000 - the swing was increased to 10 inches, but with the rear-drive lathes remaining at 9 inches. Besides the conventional V-belt drive already described, the lathe was also marketed as the comparatively rare VSL with expanding and contracting pulleys giving a useful mechanically-operated variable-speed drive system. https://rescue.bg/wp-content/plugins/formcraft/file-upload/server/content/files/1627ebee31c1c0---brother-pr-600-service-manual.pdf


The main improvements centred on increasing operator safety and ease of use: backgear no longer need two levers to be engaged, instead the initial movement of a single, electrically-interlocked lever on top of the headstock released the bull-wheel from the spindle pulley and the final push sliding the gears into engagement. A useful addition was a spindle lock, operated by a dished chrome-plated button on the face of the headstock; this greatly eased the removal and fitting of chucks and faceplates and obviated the need to use, and possibly damage, the backgears. At the same time the opportunity was taken to reposition the various headstock oil nipples so they could be reached without having to open or remove any covers - a hole being drilled through the front face of the headstock (on the sloping surface) so that an oil can could be used to lubricate the spindle-to pulley bearing before engaging backgear. Unfortunately, the rather awkward (not to say crude) method of adjusting the position of the micrometer dial on the cross-slide screw, involving a grub screw through the handle into a dimple on the shaft, was not changed. Captive nuts were fitted to the underside of the motor-mounting plate so that adjusting the belt tension on the primary-drive involved no more than slackening the clamping bolts and sliding the motor into the correct position; the countershaft spindle was increased in diameter, fitted with sealed-for-life deep-groove ball races and the motor-end cabinet door louvered to improve cooling. To improve lubrication of the countershaft bearings - and avoid having to open the door to do this - the end of the countershaft was arranged to protrude through the left-hand face of the stand so that oil could be injected by the direct application of a pressure gun. www.crea-solution.com/ckfinder/userfiles/files/canon-powershot-350-user-manual.pdf


To improve the appearance of the lathe some small but significant improvements were made to the fit and finish of various components including more precise mating of the headstock-to-changewheel guard and bed-to-screwcutting gearbox faces. The appearance of the tailstock was also cleaned up and, as a final touch, a modified catch - though still largely useless and easily-opened - was fitted to the changewheel guard. The hard-bed option was also offered on other models including the VSL and even the ME10, though it has not been possible to confirm that the older rear-drive types (which continued to be listed alongside the newer versions for some time) could be similarly equipped. Some confusion surrounds exactly when the final version of the Underdrive, the Mk. 3, was put on the market. The official release date was May 1976, but machines have been found that pre-date this, for example: AUD III-33777 with a bed casting dated 1974 - the year correctly corresponding to the Serial Number list. These lathes were distinguished by a more modern-looking stand complete with a neat splash-back, a standard-fit low-voltage halogen light unit and a rather elegant grey and brown finish. However, the designation Mk. 3 was never acknowledged in the advertising literature, though it was used in the spares department to identify the particular models. However, it is known that an ME10A, serial number 43293, was purchased direct from the Company later that year - so obviously, although the official stock list had been closed, a number of machines were left over, or built up from parts. Should you have a later example, please do let the writer know.Some changes were made to the drive styten and its controls in November, 1976 but the belts used remained the same. All versions of the VSL are very desirable - but, unfortunately (especially the 500) difficult to find. {-Variable.fc_1_url-


While early versions were very similar mechanically to an ordinary AUD - the most significant change being the fitting of a mechanical variable-speed drive system - some effort had also been made to upgrade the machine and, instead of cast-iron (used on all lesser models) the VSL, from first to last, had backgears in induction-hardened steel together with larger locating holes in the front face of the spindle bull wheel and, to improve reliability, the tumble-reverse gears ran on needle roller bearings. Pulley movement was controlled by a cable and rod system driven from a handwheel on the front of the stand. The upper drive pulley, which reacted to the movement of the motor pulley by opening and closing automatically, was carried in bearing hangers from which a second (conventional) link-type V-belt took the drive up to the headstock spindle. The speed range was typically 50 to 2000 rpm and, because the drive was infinitely variable, an electronic rev. If the tachometer is broken or missing, businesses specialising in vintage car and motorcycle restoration can often help with replacement or repair. Unfortunately, because the drive mechanism fitted to them has to be accurately aligned to work properly, the VSL is difficult to change to single-phase operation. In addition, because the coolant pump, light unit and safety-interlock transformers are also 440 volt 3-phase (though some may be on step-down transformers to run at 110V), rather than attempt to completely re-engineer the peripheral controls, it is much easier to leave everything in place and run the lathe from a phase converter or inverter. Coupling the inverter (as is usually recommended by their makers) directly to the motor and bypassing the built-in controls has been known to produce a far more effective conversion. https://gmonlinestore.com/wp-content/plugins/formcraft/file-upload/server/content/files/1627ebf0155041---brother-pr-620-manual.pdf


At one time it was believed that all gearboxes on the L00 VSL lathes had the altered internal ratios but several examples have been found in the USA (one being a VSL500 manufactured in 1977 with serial number V.S.L. 71861-L00) where this is not the case, the gearboxes being of the earlier, ordinary type. It is suspected that, while Boxford fitted a different gearbox to the earlier VSL models with the L00 spindle nose, this practice was discontinued and later editions of the manual not updated to reflect the change. If you buy a gearbox-equipped lathe that appears not to generate the pitches shown on the screwcutting plate check the special manual produced by lathes.co.uk, it shows all the ex-factory arrangement of the changewheels. One less-commonly found accessory offered for the late-model VSL lathes was a full height cabinet on the right-hand face of the stand that held a set of C5 collets and the necessary draw bar. All the gears necessary to generate metric and other pitches are now available at a good saving on the factory price. Early ME10s had a normal, full-length countershaft and were little different to the run-of-the-mill rear-drive models - the aim, presumably, being to use up supplies of no-longer-needed parts as the successful under-drive models took centre stage. Also available mounted on a special stand, the lathe was intended to run alongside the under-drive and rear-drive models and could be had in any of the three usual A (gearbox and power feeds), B (changewheels with power feeds) and C (changewheels and hand-cross feed) specifications. Early versions of the ME10 used a standard rear-drive countershaft unit - the type that is rather long front to back - but most are found with a much more compact design that significantly reduced amount of room required to install it; indeed, as a consequence, fitted to its own cabinet, the ME10 took up only a little more depth than the under-drive versions. www.kappapma.com/userfiles/files/canon-powershot-350-manual.pdf


Thus, the end result was an arrangement that made the lathe much more suitable for the home workshop - the market segment that Boxford must have been targeting. In order to achieve the reduction in back-to-front length a different design of countershaft was used and available in standard form without a clutch or, at a considerable extra cost, with. The assembly consisted of two brackets bolted to the back of the headstock with each carrying an inwards facing stud from which hung a casting that formed, at its rear, two bearing housings held on a hinged plate so that the belt tension could be relaxed to change speeds. Lathes could be supplied with either eight or sixteen speeds, the difference being achieved by using either a single or double pulley arrangement of the motor-to-countershaft drive. The 2-step motor pulley was the same size as employed on other models but the matching pair on the countershaft were, due to the lack of room under the cover, forced to be rather smaller - the result being that bottom speed was raised to 60 and the top to 2000 r.p.m. against the more normal 30 to 1300 r.p.m. of the ordinary rear-drive models and the 40 to 1400 r.p.m. of the under-drive type. Interestingly the clutch (the operating handle for which was splined and could be lifted out and replaced in any position desired) was only ever offered on the ME10, no mention of it can be found in any literature relating to the other Boxford models. One difference on most of these lathes (though it's not certain that all were so equipped) was the use of quieter-running, Oilite-bushed, tumble-reverse gears in fibre. The fibre gears can be fitted to all other models and have definite advantages if the lathe is to be used where noise might be a problem - though being weaker the gears are, of course, more likely to fail. To adjust the motor-to-countershaft belt tension meant repositioning the motor itself - however, once this had been done it was not normally necessary to make any further changes until the belt began to wear. Early examples of the CSB were different, and fitted with the novel, quick-action belt-tensioning device used on the lathes of the late 1940s - probably another case of using up no-longer-needed spares. Other evidence of clearing storeroom shelves was the use, throughout the life of the model, of an early-pattern South Bend type saddle with its simple screw-in, rather than bolt-on, cross-feed screw support bracket. Ambitious advertising in the model-engineering press of the day attempted to position the CSB as an alternative to the Myford ML7; unfortunately, the Boxford cost nearly twice as much and, while it did offer a range of advantages, there can have been few takers. Shorn of screwcutting equipment and usually, but not always, backgear as well, this model was aimed at the school and college market and had - apart from its low price - little appeal for the model or experimental engineer. The rear-drive system usually gave 4 speeds from around 200 to 1200 r.p.m. - although the writer has seen examples with 2-step pulleys on motor and countershaft to give 8. The under-drive models had 5 direct-drive speeds of 210, 340, 540, 850 and 1400 r.p.m. or, with backgear fitted, an additional 5 slower speeds. The development of the training lathes mirrored that of the more highly specified versions changing from rear to under-drive and then incorporating the other small improvements already described. The last versions were of 5-inch centre height and mounted on a version of the more modern-looking stand - and even complete with the splash-back, chuck guard and halogen light unit. Although an attractive proposition, because of their low price, the plain-turning versions are of limited use other than in a training role, for the very simplest of work - or as a back-up lathe for roughing out. Can they be converted to full-specification machines. I do know one person who managed it, but he enjoyed the unfair advantage of working night shifts at the Rolls-Royce aero-engine factory in Derby and had access to, shall we say, a rather comprehensive range of workshop facilities. In other words, the conversion is possible, but not even worth considering - unless you can find all the missing bits and enjoy the skills necessary to make the most of comprehensive turning, milling, grinding, boring and fitting facilities. Drive Systems, Countershafts and Belts: Because the 9-inch lathes had been flat-belt driven the maker, following usual practice to optimise grip, had set the pulleys as far apart as reasonably possible. However, even after a change to V-belts (and through two changes of countershaft) Boxford made no effort to take advantage of the shorter centres on which these can run to make the machines more compact. The movement was activated a quick-action, two-start thread controlled by a handle on the end of a shaft that protruded through the front face of the bed foot immediately below the headstock. When moving these lathes, take care to support the rear of the countershaft otherwise the bars on which it sits may be bent. On later rear-drive models a very heavily built, separate 16-speed countershaft of different design was fitted with the motor mounted on a rather over-engineered (even unnecessary) horizontal platform. This allowed a separate adjustment to be easily made to the motor-countershaft belt tension. At some point the new countershaft was modified and its right-hand bearing made detachable to ease belt replacement - though it was still necessary to completely dismantle the headstock if a standard V-belt was to be used. Well-used belts (or belts with stiff sections, caused by being left under tension for some considerable time) fall into and then ride up the pulleys, effectively varying the drive ratio, causing the speed to rise and fall rapidly and so induce vibration. New, high-quality machine-tool specification belts ( which we can supply, just email for details ) can make a significant improvement to the smooth running of any machine tool.An important point when dismantling Boxford drive systems: the makers were inclined to use two grub screws to lock pulleys to their shafts--the upper screw acting as a lock. So, before getting out the 14 lb hammer, do check first why it won't come apart. A serious problem with the rear-drive machines, when used in educational establishments, was the difficulty of securing the belt guards against curious fingers. With the drive now held securely in the stand behind an electrically interlocked door another advantage emerged: the depth of the machine was reduced to as little as 17-inches (400 mm). Early under-drive lathes had their countershaft-spindle bushes pressed directly into the material of the motor platform itself, with the belt-tensioning handle mounted externally on the left-hand side of the cabinet. With the handle so temptingly placed many owners were inclined to use it as an unofficial (and dangerous) substitute for a clutch. While rear-drive lathes had 6, 8 or 16 spindle speeds all the under-drive machines, with the exception of the variable-speed VSL, were limited to 10. With some variations, because of special orders or educational and training use, the usual range on the back-drive type was 30 to 1250 rpm while the Mk. 1 and Mk. 2 Underdrive types of all models (CUD, BUD and AUD) generally ran at 40, 66, 105, 165 and 270 r.p.m. in backgear and 210, 340, 540, 850 and 1400 r.p.m in open belt drive. It's well known that a lathe fitted with a spindle clutch is a good deal easier to handle than one without - and it remains a mystery why the only Boxford ever so fitted (as an option) was the ME10. Its design was similar to that used on the Myford ML7 with a brake-drum housing formed inside the countershaft drive pulley and an operating lever working through a push rod and toggle-arm that opened and closed a pair of brake shoes. Owners of clutch-equipped lathes report that the unit is not only reliable but has a pleasingly light yet positive action. Interestingly, although large numbers were sold set up in this way, some were fitted (but probably unknown to their first owners) with an imperial leadscrew driven by a metric-conversion changewheel set. The factory was obviously keen to use up stocks of leadscrews that would otherwise have languished unused in their stores - and must have guessed that the likelihood of schoolchildren ever being allowed to use a lathe to cut threads was little better than zero. This, needless to say, resulted in a great deal of confusion when the machines eventually passed into private hands. Later metric machines, and all the metric-gearbox equipped variants no matter what their year of manufacture, were fitted with a proper metric-specification 3 mm-pitch lead screw. Screwcutting Gearbox Identical to that used on the original 9-inch South Bend, the screwcutting and feeds' gearbox contained components that were neither hardened or ground and lacked oil-bath lubrication. Instead, a lever-action oil can had to be used on a series of ball-oilers to lubricate the spindle bearings with the gears attended to by squirting inside on a hit-and-miss basis. Even so, the box is remarkably reliable and, if oiled generously, will not give trouble. English and metric screwcutting versions are different, but can be easily distinguished one from the other: the English box has the diagonal line of indent holes on the right-hand half of the box's front face while for the metric version they are on the left. All the gears necessary to generate metric and other pitches are now available at a good saving on the factory price. The rear is a Timken with a 2720 cup and a 2788 cone. If a lathe without grease caps has been standing unused for several years it would be wise to strip the headstock and check to see if the lubricant has solidified. One solution, seen by the writer on an Underdrive model, was the fitting of a computer case fan in the sheet-metal belt cover on the back of the headstock. Aprons and Power Feeds Putting aside condition and accessories, what, one might ask, is the most important consideration about its specification that most be born in mind when choosing a Boxford lathe. The answer is - the apron. It is sometimes not appreciated that lathes with power-feed aprons - the Models A, AUD, B, BUD and VSL and B - not only benefited from power cross feed but also a range of slower longitudinal feeds than the Models C and CUD, the reduction through the apron's worm-and-wheel gearings meaning that the feed rate was reduced by a factor of 0.3. In addition, because the power-feed drive was taken from a key running in the slotted leadscrew, the thread in the latter was needed only for screwcutting, so preserving its accuracy and saving wear on the expensive clasp nuts. As the Model C lathes, with their plain apron, need to have the leadscrew clasp nuts engaged for a sliding feed, this causes them to be worn well before any other part of the lathe. As the nuts are only occasionally available - and expensive - any version of the Models C is, unless in really sound condition, best avoided.
