WHAT EQUIPMENT DO I NEED?

Our customer's are armed with anything from a leather-belted 1920's lathe to a full CNC arsenal. We have attempted below to show the base level of equipment required to complete our kits. Without being told youll know already that quality counts in the workshop and in general, He with the most toys, wins!.

Major Assets

A Centre Lathe, typically of at least 3 centre height (7 Swing) and 13 between centres. Screw cutting facilities are essential for many of the kits.

A Pillar Drill, typically of at least drill capacity with a motor of at least hp.

A facility for Light Milling; a good vertical slide, bolted to your lathe's cross-slide, will suffice for all but a few of the kits. However, if you do have a dedicated Milling Machine, your progress will be at a much faster pace and a few of the project will require this. If you're in the market for one, we'd suggest a vertical mill of at least 1 hp, 14 of X-travel and a speed range of 100 - 2,000 rpm.

Other Workshop BasicsLeaving aside the obvious paraphernalia, you'll need:

A good solid Bench Vice of say 4 capacity or better.

Micrometers and a 6 Vernier Calliper, the best you can afford. You should be able to determine down to 0.00025 (2 tenths) below an inch and 0.001 above an inch.

Dial Test & Dial Gauge Indicators, try for a DGI of at least travel and resolution of 0.0005. Go to town on your DTI; our has a total travel of 0.009 and resolves to 0.00005 ( of a tenth). You'll pay about 60 for a famous brand.

A Surface Plate, perhaps not essential for every kit but sooner or later you'll need a standard surface. If you have a flat bed lathe, you may get away with using it as a surface plate. Otherwise, a piece of plate glass or a second hand or imported table are equally good. 10 x 12 should do it.

Taps, Dies, Drills & Reamers, You'll need taps for BA (8,6,4 & 2), BSF (1/4, 5/16 & 3/8), BSW (5/16 & 3/8) and an some ME sizes (e.g. x 40tpi BSW) . You'll need dies for the larger sizes only (2BA to 3/8 BSW). If you're biased towards Metric and UNF/UNC, its fine to substitute these. Buy Number drills or Metric equivalents to support all of you taps. If you can find a set of machine reamers from 1/8 to 5/8 by 16ths, you'll avoid a number of fine-boring exercises. A clever man solves a problem; a wise man avoids it - Albert Einstein.

A Blowtorch, a few kits require silver soldering of components and many include silver steels that need hardening. Buy propane, NOT butane.

Drawing & Construction NotesThis is an area where we feel we add significant value for the small workshop owner. In all humilitywe think we are the best in the business by a long chalk!

Please note however that for the Universal Pillar Tool (UPT) and Versatile Dividing Head (VDH), George Thomas book, Workshop Techniques, provides all of the necessary construction notes. Whilst Hemingway drawings are included with the VDH projects, you will need to use the book for the UPT.

Materials - Our suppliers have been chosen on a basis of quality first.

Check the descriptions offered in our catalogue. In general, we aim to supply everything you will need to complete a given project. You simply add your time, experience and ingenuity!

WHATS IN A HEMINGWAY KIT?

CastingsWe now manage almost 400 patterns and core boxes! Both of the foundries that we use have been trading in the UK Midland for over 130 years. All box work and core placing is completed by hand and the castings are poured into greensand. After fettling, all castings are shot or bead blasted to improve their appearance. Defects can occur but are generally caught at the foundry or by Hemingway. Please check your castings closely before you invest in their machining. Do get in touch if you have any concerns. A level of surface defect is unavoidable but should not encroach on a major datum. Bar StockHemingway Kits holds around 4 tonnes of bar materials, chiefly in imperial dimensions. We stock over 60 different sections of steel, iron, brass, bronze, aluminium and Nylon ranging from 1/16 to 6 x 1 flats. A majority of our steel is manufactured by British Steel (Corus, Tata). We always favour free cutting grades. Please, when your kit arrives, check through the drawings and plan your use of material. It is not only the profit motive that causes us to limit lengths, we are also conscious that it will be inefficient for customers to have to machine or saw off large amounts of material to arrive at a finished dimension!

FastenersWe hold over 60 different varieties of heads, threads and lengths. A majority of our kits call for imperial fasteners, ranging from 8BA to 3/8 BSW. For this reason we only stock these imperial fasteners and a few metric sizes. Sitting here in Britain, this seems reasonable; customers have built up a stock of taps and dies that support this outlook. However, sitting in Germany or America, our position may not seem reasonable! Doubtless you will want to translate imperial threads into Course and Fine Metric, UNC and UNF and this will not affect the success of your project.

GearsFor all tools that require gears, they are supplied with the kit in blank form. That is to say the teeth themselves are fully finished leaving you to complete a few features such as threads, bores and support diameters. The worm and worm wheel pairs required to complete the dividing tools and rotary tables are intended by the designers to be generated as helicals to a pressure angle of 14 . They require dedicated assets and, with low volume runs, may seem unusually expensive. On the positive side however, the quality of our UK sources is indeed first class.

CNC Sheet MaterialThe Worden Mk 3 Tool and Cutter Grinder is a truly great product, made economically possible through the flexibility of CNC processing. The gauge of the pressings is around 1/8, affording excellent rigidity in action. Having large dedicated pressings on your bench may well be a novelty. Please remember that many of industry's worst hand injuries come from handling unprepared sheet materials! Wear gloves and file off sharp edges as a very first step. If you rely on off-hand tool grinding today, you should consider the Worden Mk3?

Other Stock ItemsHemingway Kits arrive complete! To back this claim we hold a huge variety of often difficult to find items. Along with bearings, bushes, springs and arbors, we have more exotic items such as gun-sight graticules, blended woollen felt, music wire and 5-core electrical cable. Wherever practical, we source directly from well-established UK manufacturers.

With our investments in top-end CAD systems, digital photography and colour laser printing, we have raised our designer original works to the latest industry levels. Drawings are generated from digital solid models, which are used to check all assemblies for fit and function. Isometric, sectional and detail views are included, together with a full bill of materials and machining sequences for any complex operations. Our construction notes, generally composed by the designer, allow you to understand the importance of each set-up and how it fits within the overall plan. Typically, the notes include photographs, which are invaluable for describing an operation.

Small Hole Boring Tools HK1010

Inherently centered from the top slide, these tools allow boring to be started from just a 1/4" drilled hole. Tension, induced by the pushrod, makes even the smallest tool surprisingly rigid.

There are two boring bars of each size, 1/4", 5/16" and 3/8" diameter. One bar for boring/facing the other for internal screw cutting/recessing. The kit includes 3 iron casting for the tool blocks, steel, fasteners, HSS cutting tools, a long series drill (needed to machine the boring bars) drawings and construction notes.

Between Centres Boring Bar HK1020

These three Boring Bars (13) will meet the needs of most small engineering workshops.

Each bar has a dedicated micrometer, which can be accurately positioned over the end of the cutting tool to allow precise measurement and advancement by 0.001 increments. Supplied as a kit of easily machined parts including FCMS bar, gunmetal micrometer castings, steel for the carriers, HSS cutting tools, drawing and instructions.

Speed Increaser HK1690The majority of milling machines available to small work-shop owners have a top spindle speed of less than 3,000 rpm. For most general milling purposes this is fine, but if you use cutters with a diameter of less than 2mm, this is not adequate. These smaller cutters are stock-in-trade for the clock maker for profiling, crossing out and engraving in brass.

The Speed Increaser, designed by Dick Stephen, is a simple, oil filled epicyclic gear box, offering a 3X speed increase. It can be quickly fitted to any spindle to give an output speed of up to 9,000 rpm. Please note that the design provides an output rotation OPPOSITE to input rotation. Consequently, you will need to be able to reverse your machine's spindle to use conventional cutters. Order our reversing switch (SP 1018) if required.

Along with drawings (metric only) and construction notes, the kit comes complete with all necessary material including gears, bearings, steel, bronze, and fasteners.

The virtues of parting-off from the rear of the cross-slide need hardly be mentioned. The casting bolts down solidly to the cross-slide and supports a steel turret which can be indexed precisely by 180. The kit contains material for you to produce either George Thomas' original turret, holding two parting-off blades (SP 1013 & SP 1014) or the alternative Riley turret (pictured), which accepts one parting-off blade (SP 1013) and one standard inverted lathe tool.

The kit includes casting, fasteners and springs, together with the steel required for either the GHT or Riley turret. Suitable for the Myford Super 7, ML7 and ML10 lathes this item can be modified in height to suit many lathes up to 3 centre height.

The Rear Tool Post, one of George Thomas' most elegant designs, has become a vital addition to smaller lathes for the past 30 years. Hemingway is now pleased to provide a new version, suitable for larger lathes.

Suitable for lathes with up to around 6 centre height, the kit includes the main casting and all material to complete a substantial Rear Tool Post for your Boxford, South Bend, Atlas, Chester, Harrison, Myford geared-head, Colchester, Warco, Grizzly. plus many more. The Larger Rear Tool Post is designed to engage with either a single T slot or a pair of tapped holes towards the rear of your cross slide. Whilst the turret is designed for a 3/32" parting blade (SP 1013) and an additional inverted tool, it is really a blank-canvas for any variety of insert blade holder or form tool.

Gibraltar Tool Post HK1090

Designed by Tubal Cain, who spent a lifetime in the engineering industry and was well known for his contribu-tions to the Model Engineer.

This is a substantial, no-nonsense tool post fitting directly onto the boring tables of the Myford Series 7 lathes, and is very suitable for taking heavy cuts or when working with an overhung tool. It can accept industrial HSS and Carbide Insert tools up to , a feature that affords additional rigidity and economy.

We supply the castings together with drawings, construc-tion notes and all necessary materials.

Hand Turning Rest HK1330

It is often preferable to use a hand turning rest, if only to finish a component. Thus the change from using the compound slide to a hand rest should be quick and efficient. In this design the one handle serves not only to lock the casting to the Myford Series 7 lathe bed but also to lock the tool rest. The complete rest can be fitted or removed from the lathe in a matter of seconds.

Three castings are supplied, the lower or base casting in aluminium, so as not to mark the lathe bed, the other two in cast iron. Fasteners, springs and all steel sections are included together with drawings and construction notes. You'll need a No. 505 Woodruff Cutter (SP 1000) to complete this kit.

Retracting Tool Holder HK1250

George Thomas' Retracting Tool Holder readily clamps to a 4 tool turret or a Dickson tool holder. Although propor-tioned to suit a 3 lathe, it performs perfectly in much larger equipment. The principal use is for external screw cutting. At the end of a threading pass the little ball handle is flicked backwards, whereupon the tool retracts clear of the thread. It is unnecessary to wind back the feed handle of either the cross or top-slides, thus the exact position of the tool is never lost or forgotten. At the start of the next pass, the little ball handle is pushed forwards and the tool is positively returned to its former position.

Our kit includes full drawings and construction notes together with all necessary materials. A 60 degree dovetail cutter (SP 1001) will be required to machine the dovetail slides.

Designed by G H Thomas as a modification to the Myford Super 7 Top Slide, a full kit for this prized attachment is now available! For those who haven't seen one in action, this upgrade provides truly significant advantages in both productivity and accuracy.

The small ball handle causes the complete Top Slide (with tool) to retract by around 5/32 (4mm). This greatly facilitates the cutting of both external and internal threads. It is also valuable for those final finishing cuts on both diameters and faces.

A much larger micrometer (100 x 0.001 gradua-tions) dial is used, which can be zeroed and positively locked.

Gear & Retracting Top Slide Attachment Myford Super 7

HK1240

Designed and patented by Kenneth Hart ("Martin Cleeves") in August 1970 and described in his definitive work, "Screw Cutting in the Lathe". This simple mechanism provides retraction for both external and internal thread cutting together with a unique 'swing' feature, allowing it to be flipped clear of the job for gauging those final internal cuts on a bore or thread.

The Hemingway Kits design for this item is suitable for a number of lathes up to around 5" Centre Height and importantly, it can swing clear of the fairly tall 7/16" BSF tool post of the Myford 7 range . To improve integrity, the swinging arm is milled from a steel block rather than fabricated. Extra work perhaps but the rigidity of the finished item fully justifies this approach.

The kit includes all of the necessary bar materials and fasteners together with the solid model CAD drawing set and, for interest, a copy of Mr. Hart's original patent. Unfortunately construction notes are not yet available for this project but the work is quite straight forward.

Swing & Retracting Tool Post HK1630

Swung Clear

! The dial and feed handle are connected to the feed screw by a pair of gears, which allows the feed handle to be moved upwards and outwards, thus reducing the tendency for the feed handle to foul the tailstock body or the cross slide handle.

The kit includes semi-finished blanks for the Left Hand Acme feed screw and nut (10 tpi only), the 2 necessary gears, and ALL required fasteners, springs, steel, brass, bronze and aluminium sections. Construction notes and our latest CAD drawings make this project a joy to follow; all you need to add is your time and capabilities!

A much larger micrometer (100 x 0.001 gradua-tions) dial is used, which can be zeroed and positively locked.

Gear & Retracting Top Slide Attachment Myford Super 7

HK1240

Designed and patented by Kenneth Hart ("Martin Cleeves") in August 1970 and described in his definitive work, "Screw Cutting in the Lathe". This simple mechanism provides retraction for both external and internal thread cutting together with a unique 'swing' feature, allowing it to be flipped clear of the job for gauging those final internal cuts on a bore or thread.

The Hemingway Kits design for this item is suitable for a number of lathes up to around 5" Centre Height and importantly, it can swing clear of the fairly tall 7/16" BSF tool post of the Myford 7 range . To improve integrity, the swinging arm is milled from a steel block rather than fabricated. Extra work perhaps but the rigidity of the finished item fully justifies this approach.

The kit includes all of the necessary bar materials and fasteners together with the solid model CAD drawing set and, for interest, a copy of Mr. Hart's original patent. Unfortunately construction notes are not yet available for this project but the work is quite straight forward.

! The dial and feed handle are connected to the feed screw by a pair of gears, which allows the feed handle to be moved upwards and outwards, thus reducing the tendency for the feed handle to foul the tailstock body or the cross slide handle.

The kit includes semi-finished blanks for the Left Hand Acme feed screw and nut (10 tpi only), the 2 necessary gears, and ALL required fasteners, springs, steel, brass, bronze and aluminium sections. Construction notes and our latest CAD drawings make this project a joy to follow; all you need to add is your time and capabilities!

This design, by Edgar Westbury, is thoroughly well conceived. Whilst many filing rests mount onto the bed of the lathe, by far the best location is on the cross slide where the saddle can be easily traversed to set the file's safe edge accurately along the job. The conventional screw-jack approach used for bed mounted rests cannot however be shoehorned into the space over the cross slide but this design, with its unique scissor lift action, can be sets with perfect precision to within 0.001". Hexagons and squares can be quickly and accurately "milled" on boiler fittings and fasteners before parting off. The filing rest can also be used for the production of D-bits and single lip milling cutters, which are sometimes a little difficult to measure up properly if they happen to be tapered or otherwise varied in diameter. Also, in concert with a Headstock Dividing Attachment, tangential cams for model engines will become significantly less stressful!This item can be fitted to the cross slide of virtually any lathe of around 3 1/4" centre height and upwards. The kit includes all necessary materials together drawings and Westbury's notes for both construction and use.

Centre-Height Gauge HK1820

Based on G H Thomas' elegant and simple design for setting tools at centre height relative to lathe bed (upper knife) or cross slide (lower knife). The post can be revolved to the best position for setting most lathe tools including boring bars and parting blades. This gauge is suitable for lathes up to 6 centre-height.

The kit includes drawings and construction notes together with the iron base casting, bar material and ground, hardenable flat stock for the knives.

Small Precision Boring Head

The Small Precision Boring Head, designed by Mr. G. H. Thomas, is a superb tool and a popular accessory. Suitable for bores up to 2, this tool can be run from either the lathe or miller. Machined entirely from steel, well balanced and suitable for high speed working. The feed screw ( x 40tpi) is fitted with a zero setting index which can be graduated in division of 0.001 of diameter. Our kit includes drawings and constructions notes, steel, fasten-ers, and the hardened and ground Morse Taper shank, threaded for a 3/8 BSW draw bar. You'll need a 60 dovetail cutter (SP 1001) to complete the slides.

HK1050 Large Boring Head

Designed by Dr J. Beddard. A substantial boring head that is capable of boring or fly-cutting up to 6" nominal diameter. Based on a robust, well balanced phosphor bronze casting, with piston slide adjustment and positive locking, this new boring head is ideal for use on the milling machine (indeed a milling machine is required for its construction). The tool will also swing over the bed of Myford 3 centre lathes.

This well presented kit includes the Bronze casting, ground Morse Taper arbor, HSS tool bit and all other materials required to complete the tool and its cutter bars.

HK1110 Basic Knurling Tool

The Basic Knurling Tool is a sound investment; from its first use you'll wonder why you put up with anything less?

The tool has a capacity of 3/16 - 2" and the knurls can be traversed to within a 1/4" of the chuck. A single pass will suffice in all but the toughest steels. The kit includes all necessary material together with drawings and construc-tion notes.

Knurling ToolsHave mercy on your lathe! Conventional, fixed-arm tools set up almost unbearable strain on the spindle bearings of the light lathe. Moreover, the finished knurl produced in this way is seldom satisfactory. Neither of the following designs create these strains; allowing the two knurls to 'float' on the work. Each employs two sturdy cheek plates which steady the arms enormously when traversing the work. Each design accept straight (SP 1008) or diamond (SP 1007) pattern knurls which can be ordered separately and can quickly be changed from one pattern to the other.

Precision Filing Rest HK 2410

Filing rests may strike you as old fashioned - from the era when none but the wealthy had milling machines? However, a good deal of the milling required in the small workshop consists of shaping hexagons, squares, and simple forms of cams on cylindrical work, and for this purpose, there is much to be said for a filing rest, which can be rigged in the lathe in as little time as it takes to change a tool and requires no more in the way of addi-tional equipment than a couple of ordinary files. It has the same advantage as an overhead-driven milling fixture or even a Quick-Step Mill in enabling work to be operated on in situ without removing it from the lathe chuck or between centres.

HK1115Sensitive Knurling Tool

This design closely follows that of the 'Marlco' device available until the late 60's. This item became a standard in the toolroom; allowing operators to feel the knurl being generated and adjust the pressure to both arms using a fine feed lever. This is a great advantage for jobs in aluminium and brass where care must be taken not to tear the material. It is also child's-play to run knurls of identical depth on a quantity of parts.

Moving the handle either side of its mid position causes the clutch to engage. Relax pressure on the handle and the Die Holder will again rotate and thus the die stops cutting. Very useful when screwing up to a shoulder. This tool will hold all common die diameters (1 5/16", 1", 13/16" and 5/8").

The slotted link is bolted to the rear face of the cross-slide, thus the whole of the boring table area is free for use at all times. Once the attachment has been fitted to the lathe, it is left perma-

nently in situ, and the lathe can be made ready for taper turning in a very short space of time. All that is needed is to release the cross-slide feed screw, bring the top slide into a suitable cutting position, clamp the slotted link to the guide bar and the setting up is now complete.

Accurate tapers, as required for say Morse Taper tooling, demand the exact position of the guide bar to be established. A revised precision setting micrometer, that enables quick, extremely accurate angular settings is detailed in the drawings. The kit includes LM 25 Aluminium castings for the main bracket and slotted link and a phosphor bronze casting for the slide. You will need facilities to mill the 12 long main bracket. All steel parts, including precision ground flats are provided, together with fasteners, drawings and instructions. The accessory costs well under half that of a conventional, off-the-shelf product, not having the advantages of this new design.

Designed by Dore, this attachment is rigidly constructed yet light and quick to fit. A sturdy aluminium casting (doesn't mark your boring table) fitted with substantial bronze bushes accepts a ground steel ram carrying the cutting tool. The casting is fixed to the boring table using 2 bolts in a common tee slot. Angular setting can be made by protractor and a setting dowel quickly returns the ram to the parallel position. The main casting is suitable for lathes with a centre height of 3" to 3". The kit includes 2 aluminium castings, steel, bushes, tools, fasteners, drawings and full instructions.

For 'engraving' scales or indices on dials and faces held in the lathe or dividing head. The cutting tool, held at centre height in the ground steel ram, is easily stroked backwards and forwards by the handle. The length of line cut is controlled by a 3 position index drum (units, five's and tens). The ram has tool positions at its front and back allowing engraving to be completed either along the axis of the lathe, across it or indeed at any angle. The kit includes steel, precision bushes, fasteners, spring, HSS tool, drawing and instructions.

HK1420 Grinding SpindleThis Grinding Spindle employ disc-spring loaded races to take up all bearing clearance whilst providing for thermal expansion as the spindle warms up. Maximum speed for the grinding spindle is 20,000 rpm in grease or 25,000 rpm in oil which provides for the smallest of bore grinding applications. The designer's application was for a 4" wheel running at 4,800 rpm and the pulleys and arbors are based on this.

The kit includes all necessary steel for the spindle together with "magneto style" angular contact bearings, disc-springs, lipped oil seals, drawings and construction notes. The pulleys are designed to accept 5mm Bond-a-Band belting which can be ordered separately (SP 1010).

HK2150Fitted Draw Bar

Doubtless you use a draw bar already to secure tapered tooling to a machine spindle. Many of us settle for a length of threaded bar, a washer and a nut. Beyond aesthetics, there are several sources of annoyance with this approach including finding the hole in the arbor, finding the spanner for the nut and breaking all the rule of decency by striking a threaded shaft!

The Fitted Draw Bar is a joy both to make and use. A pair of guide bushes allow the bar to find the threaded hole without fuss. A large diameter iron casting is provided for the knob, which can now be tightened by hand. When the job is complete you'll only need to loosen the knob a turn or two and strike it.

Measuring from the back end of an engaged arbor to the back of your spindle, this kit will suit lengths up to 12" with guide bushes up to 1". The 1/2" bar will accommodate an arbor thread up to 1/2" BSW/M12 (including 3/8" BSW/M10). The kit includes all necessary material, drawings and construction notes.

Where the exact diameter, surface finish and concentricity of a hole is important on a component, we reach for a reamer. The classic routine requires us to first centre drill then continue with larger sized drills. With say 0.050" to go, we swap to a single point boring tool to ensure the hole generated is concentric with the axis of the lathe - a job that can't be trusted to a flexible drill. With somewhere between 0.005" and 0.020" left on diameter, we swap the tailstock drill chuck for a Morse taper reamer, reduce the speed and feed in gradually. A perfect hole? ....almost certainly not!

A sharp, common-or-garden H7 class reamer will cut a 1/4" hole to a diameter of 0.02500" to 0.2506" with a near-ground finish and of near-perfect concentricity and parallelism. But here's the rub (pun intended!).... unless

HK2210 Floating Reamer Holder

your lathe's tailstock is aligned to the lathe's major axis within somewhat less than 0.0002", it cannot create that elegant hole. An almost immeasurable offset and/or angular mismatch can leave the hole oversized, barrelled, oval and scarred.

The answer has been known for over 100 years. Floating Reamer Holders are essential equipment on even the world's most carefully set machine tools, including CNC stations costing considerably more than the average house. For one reason or another however, they are not generally found in the small workshop? The design provided here is both elegant and sound; producing that ideal reamed hole from a tailstock barrel offset by up to 0.015" and angularly mis-aligned by up to 5. The reamer will track the bored hole, removing just those vital slivers of material.

The kit includes plans and comprehensive construction notes together with all necessary material to complete holder but not the MT sleeves. The 1" MT sleeves, available separately, are traditionally used on capstan and auto lathes to hold Morse taper tooling. They are ground all over and hardened with only a thin case that can be machined away to suit our Floating Reamer Holder.

The attachment consists of a hollow Morse Taper shank supporting a ground ram with a small capacity chuck. The chuck supplied with this kit is a German Rhm unit with a nominal capacity of 5/32" - a very well made item, ideal for small diameter drills and taps.

A lever handle operates the ram through a linkage giving just over 1" of travel and offers lots of feel with miniature drills - something that is absent using the standard tailstock barrel. This attachment should reduce the occurrence of drill breakages as one can better monitor the drill's progress and quickly back the drill out to clear swarf. Tapping (up to 2BA/M5) is also a delight since the chuck will self-feed once the tap engages with the job. The attachment can be rotated in the tailstock barrel to provide either vertical or horizontal alignment.

Along with drawings and construction notes, the kit contains all of the necessary material to complete this attachment.

HK1420 Grinding SpindleThis Grinding Spindle employ disc-spring loaded races to take up all bearing clearance whilst providing for thermal expansion as the spindle warms up. Maximum speed for the grinding spindle is 20,000 rpm in grease or 25,000 rpm in oil which provides for the smallest of bore grinding applications. The designer's application was for a 4" wheel running at 4,800 rpm and the pulleys and arbors are based on this.

The kit includes all necessary steel for the spindle together with "magneto style" angular contact bearings, disc-springs, lipped oil seals, drawings and construction notes. The pulleys are designed to accept 5mm Bond-a-Band belting which can be ordered separately (SP 1010).

HK2150Fitted Draw Bar

Doubtless you use a draw bar already to secure tapered tooling to a machine spindle. Many of us settle for a length of threaded bar, a washer and a nut. Beyond aesthetics, there are several sources of annoyance with this approach including finding the hole in the arbor, finding the spanner for the nut and breaking all the rule of decency by striking a threaded shaft!

The Fitted Draw Bar is a joy both to make and use. A pair of guide bushes allow the bar to find the threaded hole without fuss. A large diameter iron casting is provided for the knob, which can now be tightened by hand. When the job is complete you'll only need to loosen the knob a turn or two and strike it.

Measuring from the back end of an engaged arbor to the back of your spindle, this kit will suit lengths up to 12" with guide bushes up to 1". The 1/2" bar will accommodate an arbor thread up to 1/2" BSW/M12 (including 3/8" BSW/M10). The kit includes all necessary material, drawings and construction notes.

Where the exact diameter, surface finish and concentricity of a hole is important on a component, we reach for a reamer. The classic routine requires us to first centre drill then continue with larger sized drills. With say 0.050" to go, we swap to a single point boring tool to ensure the hole generated is concentric with the axis of the lathe - a job that can't be trusted to a flexible drill. With somewhere between 0.005" and 0.020" left on diameter, we swap the tailstock drill chuck for a Morse taper reamer, reduce the speed and feed in gradually. A perfect hole? ....almost certainly not!

A sharp, common-or-garden H7 class reamer will cut a 1/4" hole to a diameter of 0.02500" to 0.2506" with a near-ground finish and of near-perfect concentricity and parallelism. But here's the rub (pun intended!).... unless

HK2210 Floating Reamer Holder

your lathe's tailstock is aligned to the lathe's major axis within somewhat less than 0.0002", it cannot create that elegant hole. An almost immeasurable offset and/or angular mismatch can leave the hole oversized, barrelled, oval and scarred.

The answer has been known for over 100 years. Floating Reamer Holders are essential equipment on even the world's most carefully set machine tools, including CNC stations costing considerably more than the average house. For one reason or another however, they are not generally found in the small workshop? The design provided here is both elegant and sound; producing that ideal reamed hole from a tailstock barrel offset by up to 0.015" and angularly mis-aligned by up to 5. The reamer will track the bored hole, removing just those vital slivers of material.

The kit includes plans and comprehensive construction notes together with all necessary material to complete holder but not the MT sleeves. The 1" MT sleeves, available separately, are traditionally used on capstan and auto lathes to hold Morse taper tooling. They are ground all over and hardened with only a thin case that can be machined away to suit our Floating Reamer Holder.

The Westbury Dividing Head (WDH) can be likened to a scale Myford Dividing Head but complete with a raising block and 360 swivelling base. Using the overarm steady, the attachment will accept jobs up to a diameter of 3. If you require more than this, you can also order the Versatile Dividing Head Milling Kit (HK 1530) to provide a separate tailstock and adaptor plates to accept jobs of up to 6 1/8.

The WDH spindle arrangement is particularly well conceived. The components form a separate cartridge which can be quickly released and reversed in the main housing for axial and radial work on the lathe. Similarly, the banjo assembly supporting the direct or indirect indexing components can be re-positioned easily to suit the job in hand.

Using just the direct indexing facility (HK 2130), the attachment accepts Myford 5/8 bore change wheels with 1/8 keyways. If you happen to have a standard set of these you'll be able to index a huge number of variations. If you can only rustle up a 50t and 60t gear you can still manage to index 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50 and 60 divisions enough to suit virtually any application short of gear cutting. Then, by adding the indirect indexing components (HK 2135), there are no limitations to the number of divisions that can be struck.

Whilst suitable for any lathe or mill we have designed in a number of features which Myford lathe owners will appreciate:

The mounting holes are spaced to suit the Myford cross and vertical slides.

Mounted on the cross slide, the centre heights (3) are a perfect match.

The spindle is detailed the Myford 1 1/8 thread and pilot and a MT2 taper so will accept your chucks, faceplates, collets and arbors without adaptors.

Thousands will attest that this is also one of those truly satisfying, landmark projects with many finely crafted examples attracting gold medals at exhibitions throughout the world. This project has now been completely redrawn on our 3D system but you will need a copy of Mr. Thomas book Workshop Techniques (BK 1001) with copious notes and photographs for construction and use.

HK150XVersatile Dividing Head (VDH)

Commercial dividing heads often find disfavour among Model Engineers because they do not always fulfill the varied needs of the smaller workshops. In this design, consideration has been given not only to the wide range of possible uses of the VDH but also to the simplification of construction. In this context it may be mentioned that this dividing head generates its own division plates to a very high order of accuracy. The dimensions are such that all components can be machined on a lathe of minimum 3 centre height.

In use it will be mounted principally on the cross-slide or vertical slide. Since the spindle bore for the VDH is machined in situ on the lathe cross-slide, an exact centre height match is achieved, essential for accurate cross holes, keyways and polygonal bar work.

Simple Dividing is by means of a spring loaded plunger engaging any of the 24 holes in the face of the main wheel. Squares, hexagons, keyway cutting and tap fluting will probably be done by this method. Indirect Dividing is by means of the 60:1 worm/wheel and division plates. Just two division plates will allow most likely divisions and angular spacing to be obtained. Where prime numbers or indeed any division outside the range of the two plates are required, the Micro-Attachment gives capabilities down to 1/100th of a degree!

HK 1500 - The Full Kit containing all material necessary to complete the Versatile Dividing Head including; 2 iron castings, 2 worms, 2 worm wheels, 3 division plate blanks, 33 fasteners, 3 springs, 2 stub drills and 20 different sections of FCMS, PGMS, Brass and Silver Steel Bar.

HK 1501 - The Basic Kit, contains the material necessary to build the VDH to index solely from the 24 holes that are pre-drilled in the main wheel.

HK 1502 The Basic to Full Upgrade Kit, contains the additional material to convert the Basic VDH to the Full VDH.

HK 1510 - 4 aluminium face plate casting for the VDH spindle.

HK 1505 - Essential items ONLY: castings (2), gears (2), worms (2), division plate blanks (3), springs and stub drills.

HK 1232 - Aluminium raising block casting. For fitment to the cross-slide of larger lathes, to provide a maximum base to centre height for the VDH of 3 3/8.

Westbury Dividing Head

Edgar Westbury was of course a true pioneer of both miniature IC engines and dedicated tooling for the small workshop. In 1963 he developed a multi-functional milling attachment similar to the popular Potts Universal Milling Attachment of the time. Whilst Hemingway have the original foundry patterns for both of these classic devices, with the advent of the Quick-Step Mill we feel there is no real market for either.

One of the optional attachments for the Westbury assembly however, almost an afterthought, was a set of components called the swivelling quill holder. We saw potential for a device based on the 5 main castings here and the more we toiled at the CAD screen, the more potential we could see!

HK 1530 VDH Milling Kit

This kit consists of 2 adaptor plates and a heavy duty tailstock to bring the centre height up to 3 1/16. This provides a robust system for using the VDH on the milling machine. The adaptor plates are 5" wide by 4 1/2 long and can be tenonned to the T slots of any milling table to ensure repeatable, parallel set-ups. This kit is also a suitable addition for the Westbury Dividing Attachment (HK2130).

HK 1540 VDH Swivel Base KitWith the VDH mounted upon a Swivel Base, angular machining can readily be completed, such as making dovetail cutters and cutting bevel gears. Designed By Mr. L Downs this kit does include drawings and notes together with an iron casting and all materials.
