WHICH ENGINE

Hemingway Kits has been trading in the UK since 1976, providing small workshop owners with a growing range of Workshop Accessory kits to improve productivity, capacity and accuracy. We believe strongly in the importance of well researched and proven projects and are honoured to represent many of the world's most respected designers. It was these same beliefs that lead us to acquire Woking Precision Models in late 2006, providing a continuing source for the incomparable engine designs of Edgar Westbury, Laurence Sparey, G F King, Les Chenery, Eric Whittle, Colin Jones and Len Mason.

We are proud to present our new range of classic model engines, developed for aero, marine, automotive, locomotive and stationary scale applications. The collection includes 15 internal combustion engines of virtually every layout. We aim simply to provide the broadest and most refined range of Engines Kits available.

Internal Combustion Engines“Induction, Compression, Ignition, Exhaust” summarises the detailed development work of Nikolaus Otto, Gottlieb Daimler, Wilhelm Maybach, Karl Benz and Rudolf Diesel during the final decades of the 19th century. The world then changed!

In all of its many guises, the Internal Combustion (IC) engine has been more influential in promoting the development of machine tools, precision measurement and metallurgy within the global industrial arena than any other product in the last 100 years. This is equally true of the effect that model engines have had and are having on model engineering practices. There can be no doubt that building a running IC engine requires patience, a methodical approach and precision. The crisp bark of one's first IC engine springing into life places it's constructor within an elite global group. We believe that it is the scale of this challenge that provides model engine builders with a unique satisfaction.

‘External’ Combustion Engines You'll see that we have started to grow our collection of steam engines. Along with a replica Ransome & May Horizontal Mill Engine we have now included the B Hick & Son Oscillating Engine together with Westbury's Cygnet Royal, a unique 3 cylinder Radial Engine.

As you read through the descriptions of each model, you'll get a flavour for which project appeals to you. Since Model Engineers are such resourceful individuals, it would be unwise of us to predict that any of the projects are beyond the capabilities of a novice. Never-the-less, for your first project we believe that it is particularly important for you to be successful; one of the 2 strokes or side valve singles might prove to be a good starting point. As you progress and become comfortable with the processes and methods involved then of course the sky's the limit and each of the projects provides a different set of challenges and satisfactions.

Many customers purchase plans and construction notes for 2 or 3 of the engines before settling on a choice; running through each build and visualising the set-ups required for their particular equipment.

For each engine we have listed a description of the material kit. This kit provides the constructor with the vast majority of material required to complete the build in one sturdy box. We trust that customers will value this approach compared with the more piecemeal availability offered in the past. In general, each kit will arrive with:

CastingsWe have over 300 different foundry patterns and core boxes to support our engine range. Castings are hand poured into treated greensand, fettled then bead blasted to improve their appearance. A majority of the major components are poured in LM4 aluminium which can be machined at over 3 times the speed of steel, yielding an excellent surface for gas and water-tight joints. Gunmetal castings are specified where a component has bearing surfaces and iron is used for such parts as flywheels.

Some of our pattern equipment was first commissioned before the Second World War and we are in the process of reconditioning and replacing patterns that have become unreliable. You may find that this creates a delay in the availability of certain castings. Whilst delays are always regrettable we hope you will appreciate the benefits of this approach; there is nothing quite so frustrating as discovering an insurmountable defect after several hours work on a particular casting!

It is our intention to offer castings for the engines in complete sets rather than as individual items. However, if you need to remake a component or if you are part way through an existing project, we will always be able to help.

Gear Blanks4 stroke engines are designed with a 2:1 gear train to drive the camshaft from the crankshaft. Additional gears are needed on some models to drive auxiliaries such as lubrication and coolant pumps. These gears are supplied with accurately hobbed teeth and concentric bores. In general you will need to open the bore to suit your installation and add tapers, bosses and keyways as per drawings.

Piston Rings

Valve SpringsValve springs are included for all 4 stroke engines. Oddly however, not all designers have specified an exact valve spring… Westbury in particular seemed to assume that constructors would want to experiment with various wire gauges and free lengths as they tuned their finished engines. We have researched requirements and commissioned a number of new springs that we believe will be suitable. If you find any problems with our choice please do let us know.

BearingsIf your chosen engine runs on ball races; you'll find these included in the material kit.

Sawn Bar StockAgain, having researched each engine we have been able to bring together a majority of the bar material you will require. Unless a designer has made a particular metallurgical argument, we have specified as follows:

Crankshafts: EN16T or EN8M high tensile steel for cranks machined from the round. EN3B steel for cranks starting from a flat section.

Most of the engines are specified to run with cast iron piston rings and the correct number are supplied with each kit. The rings are fully machined, “cracked” then spread on precise formers to be heat treated in a controlled furnace over a 20 hour period. The compressed rings are produced 0.001” oversize allowing constructors to “gap” them to suit their cylinder bores.

Other Materials

Ultimately, we intend that each material kit should be 100% complete. However, the kits are currently not exhaustive and you will need to source a number of items including BA fasteners and any sheet materials.

Ignition Components

In this final section to the catalogue you will find everything required to run your engine, including coils, plugs, points and a proven Hall effect electronic ignition system. These items should be order separately – they are not included within our material kits.

Our customers' workshops vary considerably; from a flat belted 1920's lathe to a full CNC arsenal. At a minimum you will require a dependable centre lathe of at least 3½” centre height (7” swing) and 13” between centres. A screw cutting train is essential. In addition you will require some means of milling. Many of the set-ups described for the earlier engines assume that the constructor will bore onto a faceplate and mill with a vertical slide. This is perfectly feasible and acceptable but what a difference you'll enjoy if you own a light vertical miller as well!

Since precision is the “name of the game” for IC engines your measuring equipment is very important. You'll need an accurate surface plate, height gauge, a DTI resolving down to 0.00005 (1/2 of a tenth) and good quality micrometers and verniers. You should also consider investing is a Centering Microscope (see our Workshop Accessory range) to ensure that your accurate marking-out is translated into accurate machining!

The surface finishes and fits required between pistons and bores or valves and guides cannot be achieved with a cutting tool. You will need a means of lapping (or honing) internal and external cylindrical surfaces. We hope to release a number of Hemingway Workshop Accessory Kits to assist in this and other dedicated engine operations.

Whilst a number of methods are offered by designers for the production of cams, you would be wise to invest in a trustworthy Dividing Head and Rotary Table.

It may sound trite but we feel it is worth mentioning that the most important tool in the workshop is information. We have included a small selection of books relating to IC engines and hope to expand this in the future.

E T Westbury's development of the Atom series of single cylinder 2-stroke engines began in the early 1930's and continued throughout the war. Originally designed at 30cc, 15cc and then 6.3cc capacities, the Atom Minor Mk3, the final evolution of the breed, was released in 1947 to conform with 6.0cc competition limits.

With its rotary induction valve, the Atom Minor Mk3 will swing a Ø12" x 6" pitch propellor at 6,500 rpm in standard trim. A tuned example, with a 10:1 compression ratio, was bench tested in 1945 on wartime "clear pool" petrol and returned 0.29 bhp @ 11,000 rpm, reving freely through to 14,000 rpm. This would have provided 25mph perfor-mance in a 24" Hydroplane or 55mph from a 17", 6lb Tether Car! The design however was conceived primarly for model aircraft applications where it can be mounted upright or inverted.

The ignition system proposed by Westbury offers simple cam-operated contact breaker points. You may decide to go this way or to use our up-to-date hall effect system, the TIM-6. Although designed originally to accept a 3/8" x 24tpi (now M10 x 1.0mm) threaded spark plug, most builders agree that the Rimfire VR2 (1/4" x 32tpi) is a more pleasing match, aesthetically. You'll find more information in our Engine Accessories section.

Many builders choose this as their first model engine. The build is very well documented within Westbury's book, "The Atom Minor Mark III" and, as a 2-stroke, avoids the challenge of valve timing.

Atom Minor Mk3 - Westbury's Construction ManualBK 1100

This 50 page, small format book was released in 1947 at a cost of 3 shillings (£0.15/$0.25) including postage!

The book's first review in the Model Engineer magazine in November 1947 announced:

"The miniature petrol engine described in this book is of 6cc capacity and has been developed primarily for use in model aircraft. Its design and construction have been carefully planned with a view to ensuring that the merest novice with limited workshop facilities can build one without trouble. The book describes and illustrates in detail how the various castings and parts should be machined and, provided that the instructions are followed, the constructor can rest assured that the results of his efforts will be a little engine which will give him absolute satisfaction. Mr. Westbury's instructions are clear and concise, while the illustrations - mostly line drawings - leave nothing to be desired"

Although re-printed many times in the past 60 years, no one has thought to correct 3 errors in the drawings. This doesn't affect the value of the construction advice but builders should order a copy of the drawing also - which is correct.

The Wyvern WYVERN

The Wyvern is a horizontal, open crank stationary engine of the type that played a very important role in the mechanisation of industry.

Otto cycle engines, burning gas or petrol, rapidly replaced steam plant for small and medium sized applications from around 1880 onwards. The first Otto engines borrowed many of their structural features from contemporary steam engine practice, including the open horizontal frame of the orthodox mill engine. Crossely Brothers, the UK licensees of the Otto patents, were responsible for a number of important improvements including poppet valves and the clerestory combustion chamber. Westbury included all of these features in the Wyvern which was designed and launched in 1963.

With a displacement of 40cc, the Wyvern was designed to run at a constant 1,500 - 2,000rpm. Lubrication is from 3 wicked oil cups and the cylinder is water cooled. The completed engine measures 12" x 8" x 6" wide across it's two Ø6 ½" iron flywheels. The generous proportions (Bore x Stroke = Ø1¼" x 2") and simplicity of the open crank design allow this to be recommended as an engine project for new comers. With a majority of its workings exposed, it must also be said that a running Wyvern engine provides much eye-appeal!

The Wyvern - Full Material Kit HE2500

Price: £307.00

The Wyvern material kit includes the vast majority of items required to complete the engine as originally designed. Electrical components (points, coil, spark plug...) can be found separately in the IC Engine Accessory section and plans and construction notes can be ordered opposite.

The bill of materials for the Wyvern material kit includes:

(18) Aluminium, gun metal and iron castings

(2) Iron Piston Rings

(2) Valve springs

Skew gear pair (2:1) required to drive engine's camshaft

(25) Sawn lengths of bar material (free cutting and stainless steel, bronze, cast iron, brass, Tuffnol, silver steel and spring steel)

The Wyvern WYVERN

The Wyvern is a horizontal, open crank stationary engine of the type that played a very important role in the mechanisation of industry.

Otto cycle engines, burning gas or petrol, rapidly replaced steam plant for small and medium sized applications from around 1880 onwards. The first Otto engines borrowed many of their structural features from contemporary steam engine practice, including the open horizontal frame of the orthodox mill engine. Crossely Brothers, the UK licensees of the Otto patents, were responsible for a number of important improvements including poppet valves and the clerestory combustion chamber. Westbury included all of these features in the Wyvern which was designed and launched in 1963.

With a displacement of 40cc, the Wyvern was designed to run at a constant 1,500 - 2,000rpm. Lubrication is from 3 wicked oil cups and the cylinder is water cooled. The completed engine measures 12" x 8" x 6" wide across it's two Ø6 ½" iron flywheels. The generous proportions (Bore x Stroke = Ø1¼" x 2") and simplicity of the open crank design allow this to be recommended as an engine project for new comers. With a majority of its workings exposed, it must also be said that a running Wyvern engine provides much eye-appeal!

The Mastiff MASTIFF

Much like Westbury, Leonard Charlish Mason (always “Len”) was a polymath with a large variety of interests and disciplines. Following his ever popular design for Minnie, the steam traction engine, he turned his hand to petrol engines. The Mastiff is a genuine triumph of design. Mason has bought together a number of creative, trend-setting features within a compact engine which is in fact not difficult to build. Almost every aspect of the engine has been considered from first principles rather than by following convention.

Known as a great starter and a silky smooth runner, the Mastiff is a compact unit with a particularly low centre of gravity. The horizontally opposed layout provides a low head height, great balance and a stiff crankcase and crankshaft. With a Bore x Stroke of Ø3/4” x 7/8” the 4 cylinder Mastiff has a swept capacity of 25cc. The side valve arrangement helps to reduce complexity whilst providing ample breathing through Ø5/16” valves. Mason's camshaft arrangement has considerable merit for the constructor. Loose silver steel inlet and exhaust cams are hardened separately then fixed with Loctite to a mild steel shaft using an assembly jig to ensure perfect orienta-tion.

A vertical shaft for auxiliaries (driven by 2:1 skew gears) is used to power the distributor and oil pump. A pressure relief valve and an external oil pressure indicator are incorporated to ensure good lubrication from the shallow sump. The engine can be built with either a single horizontal or twin downdraft carburettors and the manifold arrangement is neatly achieved without tortu-ous routing. As the engine was conceived for marine use, water cooling is by thermo-syphon and details are given for a suitable cooling tower for stationary applications.

The Mastiff is a big engine. It stands 6 ½” tall, 8 ¾” long and 7 ½” wide over its ¼” x 32tpi plugs. Interestingly, the hole spacing for the mounting bearers is an exact match for the Myford cross-slide, making running-in a simple affair.

Following a good deal of investigation, Hemingway Kits has managed to track down and acquire the original pattern set for this British classic and for the first time since the late 1980's it is available for engine builders around the world..

The V8 Aero Engine V8

This elegant V8 won ME Magazine's coveted Gold Medal at the 1995 Olympia Exhibition. A truly magnificent project yielding a 10.6cc 4 stoke glow plug engine that is guaranteed to turn heads wherever it is displayed or flown!

Recreating an aero-engine layout that was popular in the 1920's, Eric Whittle's masterpiece closely resembles the Airdisco (Air Disposal Co.) 120 and 200 hp units used by Sir Geoffrey de Havilland in the DH51.

The engine will swing a Ø12" x 6" propeller at 7,000 rpm yet idles smoothly at 2,500rpm. The engine is just 4½" long with an overall weight of 15oz! With a 90º V8 layout using overhead valves actuated by push rods, the engine's bore x stroke = Ø0.460 x ½". Mr. Whittle states that this is a straightforward engine to build, requiring no special skills or equipment. What is required however is patience! The award winning engine took 6 months to complete and contains a total of 550 components. Fancy a chal-lenge?

The V8 Aero Engine - Material Kit HE2200

Price: £123.00

The V8 Aero Engine is made entirely from bar stock. This kit provides the majority of material required to complete the build. Customers will still have to source additional material including glow plugs and fasteners (8, 10 & 12BA). Plans and construction notes can be ordered opposite.

The bill of material includes 15 different sections of high tensile, stainless and silver steel, iron, aluminium and Dural together with the 3 specified ball races, cut blanks for the pair of timing gears and the 16 valve springs.

0.63cc / 5.0cc

The Sparey Diesels - Material Kits

L H Sparey's 0.63cc Aero Diesel & 5.0cc Aeromodeller Diesel

These 2 engine designs were launched within a 12 month period in 1946/7. Owing to their simplicity, Laurence Sparey's diesels went on to become among the most popular IC projects of all time.

The engine designs are “diesels” or more correctly; 2 stroke compression ignition engines. They are best run on a 50/50 mixture of di-ethyl ether and petrol but will burn standard diesel fuel. A contra-piston is fitted, allowing the compression ratio to be tuned once the engine is running. In 1945 the British Air Ministry relaxed its total ban on powered flight for models but set certain regula-tions including one that limited engine run-time to 45 seconds per flight. Each engine is fitted with a fairly straight forward carburettor which includes a tiny “fuel tank” which satisfied the standing rules!

Both engines share a similar layout based on a single aluminium casting for the crankcase. The cylinder barrel is cut from high tensile steel and the long piston is turned from iron bar. no piston ring is required. The single piece, overhung crankshaft is also machined from high tensile steel and runs in a long bronze main bearing. Whilst the original connecting rod was machined from gauge plate modern constructors generally choose Duraluminium and this material is included in the material kit. The transfer port is made from thin folded sheet and is silver-soldered to the cylinder. There are of course no contact breaker points or cam, no coil and no spark plug!

Sparey was a true pioneer of model engines and powered flight and these 2 projects are well known to all IC enthusi-asts. Of the two, the larger unit is considered easier to build owing to the size of the components. With a bore x stroke of Ø5/16 x ½” and standing just 3” tall, the 0.63cc unit can spin a Ø7” x 4” propeller at 5,600rpm. The 5.0cc unit stands 4.6” tall with a bore x stroke of Ø11/16” x 7/8” and will swing a Ø16” propeller at 5,600rpm.

These kits contain all of the material required to complete the build. Along with the aluminium crankcase casting your kit includes Sawn lengths of high tensile and free cutting steel, iron, aluminium, Duraluminium, silver steel, bronze, brass and spring steel, together with the neces-sary BA fasteners.

The Aero V-Twin - Material Kit HE1100

Price: £229.00

The Aero V Twin has attracted significant interest since its launch in 1983. Chenery's successful design has been reproduced by hundreds of enthusiasts over the years and examples can be seen flying on every continent. The engine sounds magnificent on a nice slow, low pass.

The engine is a 15cc (0.91 cu in), 90º V Twin 4 stroke, with overhead valves activated by push rods. The engine can be constructed either for spark ignition or glow plugs and will happily swing a 16" propeller at 6,000 rpm. The engine weighs in at just 30oz (850g) less coil and battery pack and would be perfect for scale models with wingspans of 60" - 72".

With Bore x Stroke of Ø13/16" x 7/8", the Aero V Twin's components are of a sensible size for construction on virtually any lathe and mill. Mr. Chenery's construction notes are highly detailed and we feel happy to propose this project to those with 'moderate' abilities.

This great engine has now been further enhanced. Moulds have recently been commissioned for investment castings (lost wax), providing superb detailing and integrity.

The kit includes material for the major items required to complete the engine as originally designed.

The bill of materials for the Aero V Twin kit includes:

(4) Aluminium investment castings

(4) Iron Piston Rings

(4) Valve springs

(2) Ball Races

Gear pair (2:1) required to drive engine's camshaft

Price: £85.50

Designed by Colin Jones, this 10cc engine (0.605 cu.in.) employs "modern" principles to get the job done. In common with most sports glow plug engines it features 'front' induction with the fuel/air mixture entering through a hollow crankshaft. Also employed to good effect is a classic Schnüerle port liner with exhaust, boost and 2 transfer ports on either side.

The engine weighs just 16oz. (450g) and can swing an 11" x 7.5" propeller at 12,250rpm with standard fuel and silencer fitted.

The engine is so well conceived that it's hard to believe the designer had only owned a lathe for 6 months when he embarked on this project! On this basis we are happy to propose the Jones .605 engine to Aero-modellers of all abilities.

The material kit for this engine includes 3 aluminium castings, 16 lengths of bar material (Aluminium, Dural, Brass, Bronze, Silver Steel, En8M Steel, Spring Steel) 1 Piston ring and fasteners.

To complete the engine constructors will require a 2 volt long reach glow plug.

The Whippet WHIPPET

The Whippet - Material Kit HE2400

Price: £181.50

The Whippet is an elegant 10cc, single cylinder, side valve, 4-stroke petrol engine. Designed for use in scale model boats, the Whippet was released in 1963 and was one of Edgar Westbury's final IC engine designs. Westbury felt certain that the Whippet would "set new standards for stamina, sprightliness and startability".

The engine is innovative in several respects. The crankcase and cylinder jacket are integrated into a single casting allowing the engine to have a broad base flange for attachment either to a boat's floor or to a plinth for a stationary installation. Also, by using a short stroke (bore x stroke = Ø1" x ¾") and an additional idler gear in the valve timing train, Westbury has kept the height of the engine to a minimum. Aesthetically, this gives the engine a distinctively compact appearance.

Westbury has taken great pains to simplify the design for newcomers. The overhung crankshaft is housed in plain bushes within a separate housing, avoiding the need for a split big-end bearing. A simple barrel-throttle carburettor is employed without the need for a float chamber. This is a very pleasing project, requiring just your patience and concentration to produce a classic model engine with great charm.

If you have access to the Internet, you can see Ron Chernich's build of this great little engine with detailed notes and 100's of photographs.

See: www.modelenginenews.org

The Seal SEAL

The Seal - Material Kit HE1800

One can imagine the stir this engine caused when it was released in 1947! Westbury, in his efficient manner, was at pains to explain the practical virtues of a multi-cylinder layout for scale cruisers and launches up to around 4ft long. "Reduced height... a more realistic marine installa-tion..." 'Practical' be damned; this engine promised constructors an end to the swingeing austerity of WW2. During a period when less than 5% of UK households owned a car, to build and run an engine that was every bit as sophisticated as the real thing, was the answer to a virgin's prayer! 60 years on (with around 40% of UK households owning 2 or more cars!) building and running the Seal offers no less satisfaction to the constructor.

The layout of the Seal owes a lot to pre-war automotive design, using side valves and a two bearing crank to reduce complexity. The combined inlet and exhaust manifold casting is a brave and successful touch, as is the HT distributor assembly. A carburettor design with automatic mixture compensation is provided and can be fitted in an up-draught or down-draught attitude.

The 10 castings for the Seal are aluminium, keeping the weight of the engine to a minimum. The crankshaft, perhaps the most demanding component, is cut from high tensile steel bar and has a stoke of 11/16". With a bore of Ø5/8", the swept capacity of the Seal is actually 13.8cc, rather than 15cc which is often quoted. The engine block measures 3" x 3" x 4" (H x W x L).

The Seal is known as a good starter (how could it fail with 2 sparks per revolution?) and a very flexible runner. The Seal is also known as a "rights of passage" project that each must face before being dubbed a "craftsman". To help constructors along their quest however, the build notes are highly detailed, the castings are well proven and the finished product is a valuable and renowned classic.

The kit includes material for the major items required to complete the engine as originally designed with a direct mounted distributor. The kit is not exhaustive and constructors will need to find (or make) various items including hex fasteners (7 & 8BA). In time, we hope to add a supplemental kit for those wishing to incorporate Westbury's optional vertical distributor and water pump.

The Seal Major SEAL MAJOR

At the launch of the Seal engine in 1947 Westbury noted that "It is my intention to produce designs for engines of both 15cc and 30cc, and equipped with either side or overhead valves". In 1950, with input from Westbury, the Seal Major was designed and released by David Braid.

This engine has proven to be equally as popular as the Seal. The essential differences for the Major are based solely in its capacity. Bore x stroke = Ø7/8" x 13/16" giving 32cc or 1.95cu.in. With this simple change however, every single casting becomes larger than the Seal. Larger diameter pistons and liners dictate a longer, wider block, head and sump. Additional length in these components dictates a longer manifold…and so on.

Underneath it all however, this is the same elegant 4-cylinder side-valve engine as the Seal. So, why would you choose the Seal Major? A couple of reasons:

As the American's say "nothing beats cubes" and the Major has more umph. It performs well in 6ft launches and will even power a 5 inch gauge locomotive.

For the constructor, the extra size of the compo-nents (generally 30 - 40% larger) is often wel-come.

In August 1959, author and engineer Nevil Shute wrote to a close friend:

"At the moment, however, the Seal Major engine is engaging my attention, and that will keep me busy for quite a time, although now that the book is finished I shall be taking a month or two of holiday and shall get on with it a bit quicker. So far, cylinder liners, pistons and gudgeon pins, and valve guides are finished, together with the timing spur wheels, and I am now starting work upon the crankshaft to be followed by the camshaft. I think the best plan on a job like this is to get all the bits and pieces made and then to tackle the final erection in one go when everything is to hand; otherwise one might tend to get in a bit of a muddle and one might find that parts already faced up and assembled might require some small alteration.”

2 A2-size sheets together with 38 pages of Westbury's meticulous notes.

The Sealion SEALION

The Sealion engine was released in 1959, coinciding with the launch of BMC's Mini and the opening of the UK's first motorway, the M1. The Sealion sports a gear driven overhead cam; an expensive performance feature for 1959; limited to manufacturers such as Jaguar, Aston Martin and Mercedes Benz. Whilst adding to the complex-ity of the valve train, the Sealion's SOHC arrangement offers more efficient breathing with higher compression ratios. This is a high performance engine and to many it is also Westbury's most refined and ambitious project.

The Sealion has a bore x stroke of Ø7/8" x ¾" providing a swept displacement of 29.6cc (1.8 cu.in.). The flat faced cylinder head seats 8 vertical valves, operated by short rockers from an offset, 8-lobe camshaft. The camshaft is supported by 3 bearings within a separately mounted housing, the base of which closes off the water jacket. Westbury calls for a rocker cover formed from 1/16" sheet but many constructors substitute a Perspex/Plexiglas cover. The mechanism is simply too attractive to be hidden away!

Unlike the Seal and Seal Major engines, the Sealion's crankshaft runs in 3 main bearings; 2 outboard ball races and a central spilt-shell leaded bronze bush. Connecting rods are machined from solid Duralumin and it is sug-gested that the big end cap bolts are security-wired. The Sealion engine includes an oil and water pump; a total of 10 gears make up the drives to the camshaft and auxilia-ries! A cast oil trough sits just out of reach of the crank, providing a pool for the big ends to dip into and a baffle to keep the sump level steady enough to prevent cavitation of the oil pump. The material kit includes a moulded cap for the distributor which is driven directly from the cam.

Whilst we cannot propose the Sealion as a first-project for IC constructors, we can absolutely vouch for the integrity and elegance of the design. Those craftsmen with a methodical and patient approach will thoroughly enjoy rising to the challenge.

The Seagull SEAGULL

The Seagull - Material Kit HE1700

Price: £213.00

The Seagull engine was launched in 1950 and was based aesthetically on a number of engines that were available to power river and harbour boats of the period (Russell Newbery DM, Stuart Turner P55). The layout will be familiar to period Narrow Boat enthusiast where this type of unit, coupled to a simple reversing box, would beat away merrily until the cows came home. Westbury states in the build notes that " ..there is a unique charm about a really docile and flexible engine, which must be experi-enced to be believed...”

Westbury's Seagull is an in-line twin with separate, water cooled cylinders and heads. The 2 pistons move in unison, a form known as "360º Twin". The 10cc engine has a bore x stoke of Ø3/4" x 11/16" and breathes through side valves, reducing both the number of components and their complexity. Certain successful features from the Seal engine have been incorporated, including a combined inlet/exhaust manifold casting, a carburettor with mixture compensation and an oil trough to ensure good lubrica-tion to the bottom end.

The Seagull will appeal to constructors of moderate ability who appreciate genuinely great design.

The kit includes material for all of the major items required to complete the Seagull as originally designed. Constructors will need to find or make fasteners (6 & 8BA hex screws). The bill of materials includes:

(13) Aluminium sand castings

(4) Iron Piston Rings

(3) Timing Gear Train

The Wallaby WALLABY

The Wallaby - Material Kit HE2300

Following the successful launch of the diesel powered Aveling & Porter Road Roller in 1938, Westbury turned his attention to developing an IC powered model locomotive. In 1941 the 3½" gauge 1831 LMS Shunting Locomotive was released. As one would expect, the design was highly innovative and performance was exceptional. As Westbury anticipated however, locomotive enthusiast (then as now) would not easily abandon steam! The powerful engine developed for this project however was adapted to suit many application, including both marine and stationary installations. In 1962 a "Mk2" version of this much renowned engine was created and dubbed The Wallaby.

Those in-the-know site the Wallaby as an example of a truly refined and durable power plant. Westbury, a master of understatement simply noted that it was "an engine capable of packing a good punch for its size, yet docile and flexible withal, and not too difficult to construct". With a bore x stroke of Ø1" x 1 1/8", the 360º vertical twin provides a useful 29.0cc of swept displacement. Heavy split main bearings ensure a rigid bottom end and the camshaft, driven by broad timing gears, operates over-head valve gear via push rods. Unusually, the valves are arranged so that the inlet ports are central and the outlet ports outboard, facing fore and aft. The carburettor, complete with float chamber is borrowed from the Kiwi Mk2 and provides a good level of control with mechanical mixture compensation.

The kit includes material for all of the major items required to complete the Wallaby as originally designed. Whilst deemed by Westbury as an optional fitment, the material kit includes the items necessary to add forced lubrication. Why settle for less? A centrifugal clutch mechanism was also developed for this engine but we have decided to list this separately in the engine accessories section as we feel it will be a valuable addition to many engines in our range. The bill of materials includes:

(17) Aluminium and Gun Metal castings.

The Kiwi Mk 2 KIWI

The Kiwi Mk2 is a 15cc, OHV 4 stroke with a big reputa-tion. Originally designed by Westbury in 1935 it was a tremendously popular project due in no small way to the complete absence of commercially available model engines during the war years. When updating the design in 1960 Westbury commented that "the Kiwi has always been the favourite of the beginner, who could be fairly sure of making it and getting it to run successfully". Westbury seldom quoted performance figures for his designs, arguing that build quality varied so widely that a hard number would be misleading. However... the Mk1 Kiwi returned 5/8bhp @ 8,500 rpm on Professor D H Chaddick's custom built dynamometer; enough to power a 24" hydroplane at 40mph! With its ball race main bearings, stiffened crankcase and cooler running cylinder, your Mk2 Kiwi could well hit 50bhp per litre!

The engine has a conventional British motorcycle appear-ance; perhaps a BSA C15 or a Norton ES2. With a bore x stroke of Ø1" x 1 1/8", the Kiwi stands 6" tall from sump to rockers. The Kiwi's simplified camshaft operates open push rods, rockers and vertical overhead valves so aspira-tion of the running engine can be readily observed; a fascinating feature! The carburettor for the Kiwi is simple yet well conceived; providing the mixture compensation that is essential to flexible running. A cast float chamber accepts a balsa wood (or cork) float for further refinement. Lubrication is via a metered drip feed system which is remotely mounted from the engine.

The castings for this project are well proven and the engine can be ordered with either an air cooled or water cooled cylinder jacket and head. The Kiwi has been successfully built and run by thousands of IC novices over the past 70 years and we trust that, having built one, you too will appreciate the appeal of this timeless classic.

The Ransome & May Mill Engine - 1850 RANSOME & MAY

Ransomes, founded in 1799, made their name in chilled-cast plough-shares before entering the steam markets in the early 1840's. This 8nhp mill engine was demonstrated at the Great Exhibition of London in 1851 with a size and functionality that set the Ransome brand apart through-out both the British and Russian Empires.

The Ransome family of Ipswich, like the Cadburys, the Clarks, the Lloyds, the Wedgewoods and the Darbys, set out with their Quaker beliefs to do genuine good rather than simply to make money. In 1849 James Ransome erected a Workman's Hall to house "single men and lads....with a cheerful room to spend his evenings in and to prevent a too early and therefore improvident marriage, in order to escape from the discomfort attending a solitary existence".

Geoffrey King, a professional Engineer and member of the Newcomen Society, designed this 1/12th scale replica in 1958 from an example which was in service until 1921. With a bore x stroke of ¾" x 1½", the engine has a double acting slide valve with 4 bar guides, a marine type big-end, an eccentric driven feed pump, a hand cranked stop valve and a Watts type governor, driven by ordinary chain running in grooved pulleys. Under steam the engine is a delight, especially with its governor weighted for slow running. The engine sits on a bedplate measur-ing 9 1/8" x 2 ¼" with a flywheel diameter of 7".

Whilst construction is somewhat more involved than say a Stuart Victoria engine, the Ransome & May replica pays-off handsomely with elegant gunmetal adopted for all of the major mechanisms.

The engine is beautifully presented on 4 A2 sheets. Also included is an article by Mr. King detailing the engine's installation in a 3 story Norfolk grist (flour) mill. No construction notes are available for this engine.

B. Hick & Son - Oscillating Engine The Cygnet RoyalHICKOSC CYGNET

"These are indeed glorious times for the engineers!" James Nasmyth, 11 July 1836

Following a six year appreticeship as a draughtsman with Fenton & Murray, Benjamin Hicks left to become manager of the Leeds Union Foundry, the largest steam engine works in Lancashire. At this point, in 1810, he was just 20 years old. By 1833, B Hick & Son opened shop at the Soho Foundry in Bolton, specialising in stationary steam engines for both marine and industrial applications.

On Saturday June 30, 1838, under the heading "Procession in Bolton marking the coronation of Victoria" the Bolton Chronicle reported:Mr. Hick's men, of the Soho Foundry, made a most splendid display of flags and banners, upon which were painted representations of various steam engines and machinery. The whole was tasteful and classical in the highest degree. All the workpeople, numbering more than 400, engaged at the Soho Foundry, were liberally regaled by Mr. Hick, with good old English fare, the dinner consisted of roast beef, plumb pudding, and excellent ale. The appearance of the men was most gratifying. Mr. Hick himself presided, and greatly added to the conviviality of the occasion by his gentle manners and agreeable demeanour. The health of the Queen was proposed and drunk with the most clamorous enthusiasm. A band was in attendance, which played during the dinner a number of popular airs, and after the repast, struck up a merry dance. The evening was spent in unalloyed mirth, and concluded in a manner highly satisfactory to both master and men.

This elegant oscillating engine, producing 2nhp, was displayed under steam by Hick, Hargreave & Co at the Great Exhibition in 1851 where it powered a Ryder forging machine. Like all oscillating engines, it is a real joy to watch! Our model is a faithful "foot to inch" scale replica of the original, designed from company archives by Geoffrey King in 1957. This is a small engine which can be produced on virtually any lathe. The bore and stroke measure Ø7/16" x 15/16", the flywheel has a diameter of Ø3½" and the complete model measures 5¾"x 3½" x 5" (LxWxH).

With care and patience, this project will yield a delightfully proportioned engine with a captivating action.

There can be no doubt that Edgar Westbury (1896-1970) was a true, but unassuming, giant of the model engineering fraternity. Designing and building over 60 unique IC and steam engines, one wonders how he also found time to edit bi-weekly issues of the Model Engineer magazine for almost 20 years!

Westbury's Cygnet Royal, a 3 cylinder radial steam engine was conceived in 1962 as an experimental crossover between steam and IC build techniques. It was designed as a marine engine for use behind a flash steam generator, withstanding high pressure (80psi and upwards) and running at high speed (typically 3,000rpm +). In many ways, with its in-line orbital distribution valve, it behaves as a 2 stroke IC engine but running much more smoothly. The single throw crankshaft runs on ball bearings within an oil filled crankcase.

As well as being a elegant curiosity, the Cygnet Royal is a good deal lighter and more compact than conventional steam engines of a similar output. Measuring around 4" x 4" x 4", the engine has a bore x stroke of Ø5/8" x ½". Having 3 cylinders, the Cygnet Royal is also a self-starting engine - just add steam (or compressed air) and off it goes!

As well as being a elegant curiosity, the Cygnet Royal is a good deal lighter and more compact than conventional steam engines of a similar output. Measuring around 4" x 4" x 4", the engine has a bore x stroke of Ø5/8" x ½". Having 3 cylinders, the Cygnet Royal is also a self-starting engine - just add steam (or compressed air) and off it goes!

Additional Rare Earth Magnet HEA 1070

Hall Effect System (4.8 - 6.0 v) HEA 1060

The basics of Spark Ignition are easy to grasp. The compressed fuel/air mixture drawn into your engine is detonated by an electrical spark, generated when the piston reaches Top Dead Centre (or within a few degrees). Now repeat - 100 times each second (6,000rpm)!

A majority of our IC Engines were developed to run with contact breaker points. CB point systems rely upon the profile of a rotating cam to open and close the gap between 2 tungsten "pads". Opening the points triggers the high tension coil to send a single jolt down the HT lead and across the spark plug gap. Kapow!!

This method survived in the automotive markets until around 1979, when Lucas, Bosch, Magnetti Marelli and Nipon Denso all changed over to transistor-ised, Hall Effect devices. Interestingly, the effect was discovered by Edwin Hall in 1879, 100 years before this application! The new devices signalled the demise of points and fiendishly clever auto-advance mechanisms. Overnight there was no gap to set, no mis-matched faces to arc and burn and no high speed points-bounce.

The TIM-6c kit brings the same advantages to model IC Engines. In place of the cam, a tiny rare earth magnet (Ø1/8" x 1/16" thick) is mounted on a drum or disc. As this magnet passes in close proximity to a remotely mounted sensor, the circuit board amplifies the current induced by the magnet and triggers the HT coil. Kapow again!

The TIM-6c system arrives as a kit of 10 electrical components, a circuit board (1"

Tiny magnet - Ø1/8" x 1/16" thick. Very strong for its size. With the TIM-6c system above, you'll need extra magnets for multi-cylinder engines. Alternatively, if you know you're going to lose it, why not order a spare one in advance.....?

x 1 3/8" - easily hidden) and the necessary instructions. The TIM-6c system works at between 4.8 and 6.0V; perfectly compatible with the "Exciter" coil shown below and any of our spark plugs.

One rare earth magnet comes with the kit so if you're building a single cylinder engine this is all you need. Otherwise, you should order one extra magnet for a twin, 3 extra magnets for 4 cylinders and so on.

Price: £17.50 each

Spark Plugs

! Rimfire VR2 Spark Plug (1/4” x 32tpi)

Rimfire spark plugs were designed to outperform and replace the older generations of miniature spark plugs from the 1930s through the 1950s. Their physical sizes, designations, threads, and reach are nearly identical to the plugs that were most commonly used, but with added technological features to increase an engines performance. They are manufactured from the highest grades of material available and surpass that of most full-size automobile spark plugs.

This plug size is specified for the Aero V Twin, the Whippet, the Seagull, the Seal, the Seal Major and the Sealion engines. The VR2 will also run perfectly in the Atom Minor Mk3, the Phoenix, the Kiwi and the Wallaby even though these engines were originally designed to accept larger 3/8” x 24tpi plugs. Many constructors feel that the Rimfire VR2 is aesthetically more to scale.

Price: £6.80 each

! NGK CM-6 (M10 x 1mm Pitch)

These are among the smallest mass manufactured plugs avail-able and benefit from having a mass manufactured price. They are a suitable alternative for engines originally designed to accept 3/8” x 24tpi plugs that were commonly available in yester-year. In our engine range they will suit the Kiwi, the Phoenix, the Atom Minor Mk3, the Wallaby and the Wyvern. The CM-6 has a reach of 0.339” and the hex measures 8.6mm AF.

Price: £14.50 each kit

! Circular Discharge Plug (¼” x 32tpi)

These spark plugs are supplied as a material kit with drawings and instructions for you to make your own! They are not difficult to produce and you can vary the “reach” to some extent to suit your particular installation. Whilst these plugs will run in most applications, they are particularly suitable for slower running engines which may have a tendency to oil-up conventional plugs. Each kit includes plans, construction notes together and sufficient material to produce 2 plugs!

Please note that you will also require a high temperature

adhesive such as JB Weld (HEA 1040).

Tungsten Points HEA 1080

Price: £1.30 each

Tungsten contact breaker points, once prolific in automotive ignition systems, have become virtually unobtain-able in recent years. Tungsten is a robust, brittle metal with a high resistance to temperature and a high melting point – withstanding surface pitting for 100's of engine hours.

By a happy chance, we have obtained a decent stock of solid tungsten discs measuring Ø0.160” x 0.045” thick with ground and polished faces. These can be easily brazed to spring steel or headless bolts with a silver based material such as Easyflo. In theory at least… the tungsten can be machined with a carbide tool run at 100 – 200 rpm with a good supply of coolant.

Centrifugal Clutch Kit HEA 1030

This assembly was designed by Westbury in 1941 for use on his 1831 IC Locomotive and detailed again for the Wallaby engine. We believe that this will be an interesting accessory for other engines as well; allowing a simple means of decoupling the engine from its load at low engine speed. The kit comes with construction notes 2 gunmetal castings, sawn bar for an iron flywheel and a suitable ball race. The 4 tension springs are not included. You will need to experiment in order to achieve the best results. If you need a spring winder and wire see our Workshop Accessory Catalogue. Westbury suggests engagement should begin at 800rpm and states there is a “wide transition between first engagement and full torque”.

JB Weld HEA 1040

Price: £7.80

This product is the answer to a many a prayer! It is a 2 part epoxy adhesive suitable for use on all of the materials specified in our engines. What sets it apart from any-old epoxy adhesive is its unique specification. It can with-stand temperatures up to 500ºF. Once set, it is resistant to water, petrol, oil and virtually any chemical including acids. It can be used as an adhesive, laminate, plug, filler, sealant, or electrical insulator. After 15-24 hours of curing at room temperature, it can be drilled, ground, tapped, machined, filed, sanded, and painted. It dries to a dark grey (steel like) colour.

The product comes in 2 x 28.7g (1oz.!) tubes together with instructions and interesting testimonials!

Terms of Business

PaymentWe accept payment by credit & debit cards, cheque or UK Postal Order (payable to Hemingway Kits) and cash at your risk. We accept Visa, MasterCard, Maestro and Switch cards. You may send your card information via post, phone, fax or over the Internet, making use of the 128 bit encryption with our on-line catalogue. If you are shopping from outside the UK, place your order and your card company will convert the Pounds Sterling transaction to your own currency.

Shipping UKWe have negotiated a 2/3 day delivery rate of £8.25 for all UK orders above 2kg. Below this weight, one of us will just have to walk down to the Post Office....

EXPORTFor parcels weighing below 2kg, we will send your delivery by the Royal Mail's small packet service. Occasionally it makes sense for us to split your kit into 2 separate boxes (say 1.9kg and 0.5kg) to use this service! Above 2.0kg we use Fedex and DHL. Typical delivery times are 5 days to either the Antipodes, the Colonies or the Continent. Please get in touch for a quotation.

Delivery Lead TimesIn general, we "Make to Order" rather than "Make to Stock". We aim to despatch your UK orders within 3 business days and International orders within 5 days. Occasionally, you'll catch us waiting for certain items (typically castings) to arrive.... At our option, we may decide to forward your incomplete kit together with a note declaring the shortage(s). This allows you to make a start. We will then forward, at our expense, the missing items once they are available. If the delay is likely to be substantial, or if we are missing an item without which you can't start your project, we'll get in touch and discuss it with you - under these circumstances we won't process your payment until everything is ready to ship.

VAT Included - Registration No. GB 876 6053 91Hemingway Kits is registered for Value Added Tax and all of the prices shown include this tax at a rate of 20.0%. For shipments made to addresses outside of the European Community, this tax will be discounted from your order before we process your card payment. This discount (or refund) does not apply to shipping costs or orders for plans and books. Incidentally, to remove 20% from a tax-inclusive price you must divide by 1.2 (NOT multiply by 0.8).

Your SatisfactionIt is very important to us that you are satisfied with your order. Please do contact us if you have a concern and we promise to address it immediately.

The occasional faulty casting is inevitable from the low volume processes that we employ. Any such casting returned to us will be replaced free of charge, together with a credit note for the shipping cost which you have incurred. We cannot, however, accept claims for labour or other costs arising from such faults.

There's also an infinitesimally small chance that YOU will scrap an item?! Please get in touch and you'll find we show great mercy in pricing replacement materials.

All products are described and shown as accurately as possible. However, customers are given the full benefit, AT ONCE, of any improvements to designs and specifications.

Our Satisfaction!We love what we do and are always pleased to hear about your successful projects. Photograph are always welcome together with any comments you can offer about your improvements, alternative set-ups and product configurations for specific machine tools or jobs.

Privacy PolicyHemingway Kits do not disclose customers' information to third parties without their full consent.

LiabilityWe the suppliers, Hemingway Kits, will not accept responsibility for personal injury or damage to property arising directly or indirectly out of the use by customers of our kits and workshop accessories nor will we accept liability for any claims made for personal injury or damage to property resulting from customers carrying out any instructions supplied by us (such instructions being for information purposes only).

The placing of an order shall be deemed to be acceptance of the above terms of business.
