The combustion engine “Little Karl” is, as the name suggests, the small version of our popular combustion engine Karl. With this kit, particular emphasis was placed on the fact that it can be made in a small hobby workshop with a small lathe. Thanks to its simple construction, this model is also suitable for beginners in technical model making. In contrast to the large stationary engine Karl, this model does not have an ignition with a spark plug but rather a Glow plug. This circumstance makes both the construction of the model and its operation easier because the ignition timing does not need to be adjusted. Of course, this model also has speed control via Hit & Miss control. The combustion engine “Little Karl” with glow plug has a stable frame made of milled brass parts. The crankshaft is guided in two gunmetal plain bearings. The cylinder sleeve consists of a precision brass tube that no longer needs to be processed inside. An aluminum piston runs in the tube. The cylinder head and cooling jacket are also made of aluminum. Most other components such as the carburettor, tank, rocker arms and controls are made of brass. The entire motor is mounted on an aluminum base which in turn rests on two oak wooden runners. The two 80mm flywheels and the pulley are made of cast steel using the lost wax casting process and are of excellent quality. All materials required to build the combustion engine "Little Karl", such as screws, springs and ignition parts, are included in the kit. All milled parts are prepared so that they only need to be deburred and possibly drilled. All turned parts are included in the kit unmachined and must be manufactured according to the drawing. To build the Hit & Miss Motors requires a small lathe, a drill and a gas burner for soft soldering. The following hand tool is also required (tap M2, M3, M4, tap UNEF1/ 4 x 32, Dies M4, M6, reamer 3H7, 5H7, 6H7, 8H7) files and a drill set are necessary. All you need to wire the glow plug is a pair of side cutters, wire strippers and a soldering iron. You also need a baby battery with at least 3000 mAh. The battery is not included in the kit but can be ordered from us. If you would like to find out in advance which work steps you have to carry out when manufacturing this combustion engine, take a look at our Bengs model building magazine Construction report of the combustion engine "The Little Karl" with glow plug.

If the engine has reached too high a speed, a slide prevents the exhaust valve from closing. This means the engine runs freely. No compression can occur in the cylinder chamber and the engine neither sucks in fresh gasoline nor ignites the air-fuel mixture. The Hit & Miss regulation is called suspension regulation in German. The misfire control was mainly used in the USA by various companies for internal combustion engines from 1890 to 1940. The scope of delivery includes: finished CNC milled milled parts Raw material for the turned partsRough casting part for the flywheels 80mm Raw casting part for the belt wheel Two wooden runners made of oak All required screws, nuts, gears and sealing rings Drawings of the combustion engine "Little Karl" (24 sheets) and construction instructions (11 sheets) Switch, battery compartment, cable and glow plug (Battery Baby battery not included is available from us 

Stationary engine with hit and mismatch were used from 1890 to 1940 for a variety of tasks. The design with lying cylinder, open crankshaft and two flywheels was one of the most popular. These engines have been used in many farms to drive threshing machines, pumps, or grain grinders. But also in many craft and industrial engines, these combustion engines have been used in various sizes. Particularly in the American area, the speed control system has been widespread through a misfire control. The open crankshaft and the open rocker arms allow a very good view of the workings in an internal combustion engine. With the material kit for the internal combustion engine "Karl" you can build a fully functional combustion engine. The material kit contains all required parts including the ignition. The engine has a functioning speed control, which is controlled by a hit and miss misfire control. The ignition is concealed in the base of the machine, as well as in the wooden box behind the machine base. Dimensions of the model internal combustion engine 'Karl': Height with wooden runners: 192mm Overall length: 440mm Width overall: 180mm Length without skids and wooden box: 283mm Dia. Piston: 25mm Flywheel D .: 140mm Speed: 600-1500 rpm The machine foot of the station motor is a heavy gray cast iron base. The piston of the machine is also made of gray cast iron round material.

When the engine has reached an excessive speed, a slider prevents the exhaust valve from closing. Thus the motor runs freely. No compression in the cylinder chamber can occur and the engine does not suck up any fresh gasoline or ignite the air fuel mixture. The Hit & Miss regulationt is mentioned in the German suspension rules. The intermittent control system was used from 1890 to 1940 mainly in the USA by different companies with internal combustion engines.    

The 4-cylinder in-line engine "Marc" is based on a historical model. The model was a four-cylinder in-line engine that was manufactured by the American company Holt at the beginning of the 20th century. This engine was mainly used in bulldozers and tracked tractors. This engine was available in 2, 4 and 6 cylinder versions. In 1925, the Holt company became the Caterpillar company, which still exists today. The engine does not consist of a cast engine block, as was usual later, but still has individual cylinders. This design is visually very appealing and makes it possible to offer the engine as a material kit. Speed control via centrifugal governor Carburetor with adjustable throttle valve Cooling circuit with cooling water pump Cooler with fan With the 4-cylinder in-line engine "Marc" material kit, you can build a fully functional combustion engine yourself. The material kit contains all the necessary parts including the ignition. The engine has a functioning speed control using a centrifugal governor.

The Jonas vertical combustion engine was based on the appearance of the early diesel engines that were created at the beginning of the 20th century. A frame that has the shape of an A was typical. In addition, the early diesel engines were mostly long-stroke engines, which resulted in a slim and tall design. The overhead camshaft, which was driven by a long vertical shaft, was also typical. Back then, as now in our model, the speed was controlled via a centrifugal governor mounted on top of the vertical shaft. Our combustion engine runs on gasoline, but operation on diesel is not possible. Speed control via centrifugal governor Carburetor with adjustable throttle valve Cooling circuit with cooling water pump Fuel pump delivery rate adjustable Ignition timing adjustment Camshaft drive via screw wheel 45° With the material kit for the water-cooled 4-stroke engine "Jonas" you can build a fully functional internal combustion engine yourself. The material kit contains all the necessary parts including the ignition. The engine has functioning speed control using a centrifugal governor. A cooling water pump pumps water through a radiator into the cylinder jacket and back again. The engine also has a fuel pump that pumps the fuel towards the carburettor into an intermediate tank. The pumping volume of the fuel pump can be adjusted as required. The breaker ignition is located in the cast base. The ignition is supplied with voltage via a 12 V 2 A power supply. The power supply is also included.Dimensions of the model combustion engine 'Jonas': Height with wooden base: 500mm Dimensions of the base plate: 350mm x 210mm Piston diameter: 25mm Flywheel D.: 200mm Speed speed: 200-600 rpm Weight: 11.8kg The machine base of the vertical stationary motor is a heavy gray cast iron base. This heavy base gives the model sufficient stability. The piston of the combustion engine is also made from gray cast iron round material. In this engine the piston also has a piston ring. The piston ring is already included in the kit. A hydraulic cylinder tube is used as a cylinder, which is already finished on the inside and has an excellent surface. The cylinder head is made of aluminum, the cooling jacket is hollow and is flushed with cooling water via a cooling water pump. The 200mm flywheel is made of gray cast iron and can be ordered pre-machined upon request.

This casting set was designed on the model of a Dürkopp gas engine. The finished model has an impressive total height of 430mm and many special details. This casting set was previously marketed by Ravensburger steam models. From now on this cast kit is available from us. To build this casting set, you should already have experience in this model construction area. The flywheel with 280mm diameter requires a large and stable lathe, with a sufficiently large lining and planar disc. You also need a larger milling machine to finish the castings. This engine is a special construction, the crankshaft lies above and the piston plunges down into the cylinder. This type of motor is called the plunger motor. A cam disk is driven via two bevel gears, through which the inlet and outlet valves are actuated. The valves are not mounted in the cylinder chamber, as are customary today, but are located outside in their own valve housings. In addition, this motor is equipped with a centrifugal governor, which can be used to regulate the amount of the incoming gas. The Dürkopp immersion piston engine has been designed for operation with gas. It can be operated directly with gas from a propane bottle. Of course, this engine can also be operated with petrol. For this, however, the gas mixer must be exchanged for a carburettor. Our experience has shown that this engine runs with gas much smoother and more beautiful. We recommend operating with gas. Required tools and machinesFor the construction of the combustor, an extensive workshop, with a large lathing machine and a medium-sized stable milling machine is needed. The lathe should be able to machine a flywheel with an outer diameter of 300 mm. For machining the castings on the lathe, a planar disk should also be present. In addition, a stator drilling machine and a torch for soldering larger parts will be available. Furthermore, hand tools (taps M2, M3, M4, M6x0,75, M10x1 / cutter M2, M3, M4, M8, M6x0,75, M10x1 / reamers 3H7, 4H7, 5H7, 6H7,15H7 files, drill set) are necessary , To solder the ignition, a soldering iron is required for this model. We have prepared for you an extensive construction report of the Dürkopp gas engine. The building report is subdivided into subassemblies and is designed to assist you in the manufacture of the engine. Furthermore, you can see in the building report whether your machine park is of sufficient size.

With this set of cast parts you have the opportunity to build a prototypical model engine of the type that was used as a large engine at the beginning of the last century (e.g. to generate electricity in factories). The large piston stroke and large bore enable a speed of less than 130 rpm. The quiet and slow running of the engine arouses true enthusiasm among connoisseurs. The valves are controlled via a timing chain that drives the camshaft. The dimensions of the gas engine are already clear from the weight. It weighs around 50 kg. With this engine, a true-to-life power plant can be built to generate electricity. This set of castings was previously sold by the Ravensburger Dampfmodelle company. This casting set, drawing and spare parts are now available from us in the Bengs Modellbau online shop. We supply most of the special parts needed to build the engine. You can use the components we offer as ignition. Here you can find the parts for the ignition (Ignition coil , Interrupter, Kondensator, Spark plug).  The castings are molded and cast by hand in a small foundry in Germany. Most of the castings are made of GG25, the cylinder head is delivered in cast aluminum. Due to the large dimensions of this engine, you should have an excellently equipped workshop with a large lathe and a large milling machine.

The Stirling engine "The Great Laura" is similar in design to a horizontal plank hot air engine from 1910. Like every Stirling engine, this horizontal, air-cooled heat engine has two cylinders with pistons, the displacement cylinder and the working cylinder. The working cylinder is made of steel, the displacement cylinder is made of aluminum with a 60mm diameter due to better thermal conductivity. In addition, the displacement cylinder is equipped with cooling fins to ensure the machine runs for as long as possible. Like its historical model, the hot air engine has a flywheel and a pulley. The modelThe Stirling engine As you can tell from the name, “The Big Laura” is a large version of our very successful “Laura” Stirling engine kit. The size of this model brings with it some advantages. Due to its large surface area, the Stirling engine can dissipate heat better and therefore run longer. The tank of the Stirling engine "The Big Laura" is extra large. A tank full of denatured alcohol lasts 8-10 hours depending on the size of the flame. In addition, significantly lower speeds are possible with this large Stirling engine than with small model Stirling engines. But even high speeds are no problem for the model. The speed of this hot air motor can be controlled using an adjusting wheel. The burner is firmly connected to the model and the base plate. A 140mm flywheel and a pulley in our well-known cast steel quality run on the drive shaft. The working cylinder consists of a hydraulic cylinder tube and no longer needs to be processed on the inside. The included oak base plate is also pre-milled.  The blueprint and construction instructions included with the Stirling engine are very extensive, detailed and easy to understand. For the model maker who has always wanted to build a large Stirling engine himself, the Stirling engine "The Big Laura" is a well-suited model. Dimensions of the model Stirling engine Base plate: 255mm x 120mm Flywheel: 140mm Pulley: 56mm Total height: 120mm Working piston: 30mm Displacer piston: 35mm Overall length: 410mm < span style="letter-spacing:0px;">Included in the scope of delivery of the material kit Stirling engine "The Great Laura" are Milled wooden base plate Finishedmilled milled parts Brass, steel, stainless steel and silver steel Raw material for the turned parts Cylinder sleeve made of hydraulic cylinder tube  Flywheel and pulley made of cast steelAll required screws, nuts, gaskets, grub screws and wick  Construction plan model Stirling "The big Laura" drawings (14 sheets) and construction instructions (9 sheets) All materials, screws and accessories required to build the Stirling engine "The Great Laura" are included in the kit.

To build the Stirling you will need a medium-sized lathe, a column drill and a gas burner for brazing and soft soldering. There are also hand tools that should be in every "model making machine shop" (tap M2, M3, M4, M8x0.75, M10x1 die M3, M8x0.75, M10x1 reamer 3H7, 4H7, 5H7, 8H7, 10H7) files and a drill set is necessary. You can find a detailed construction report for this model in our Bengs model building magazine. In the Construction report of the Stirling engine “The Great Laura” you will find lots of pictures and explanatory texts. This means you can find out in advance about the work that needs to be done. But the Stirling engine construction report can also help you during construction.

The Stirling engine 'Laura' has parallel cylinders; this type is called gamma type. The engine is a visually very appealing showcase and demonstration model which can be put into operation at any time and anywhere. The Stirling engine 'Laura' material kit is constructed according to the well-known BENGS model building principle. All milled parts are prepared to such an extent that they only need to be deburred and possibly drilled. The turned parts are unprocessed. The flywheel is pre-turned and milled to such an extent that it can also be finished on a small lathe.The scope of delivery of the Stirling engine Laura material kit includes: Finished milled parts Raw material for the turned parts very clean 80mm cast flywheel Milled oak base plate All required screws, nuts, Duran glass tubes, Ball bearings and O-rings Construction plan Stirling engine Laura drawings (7 sheets) and construction instructions (3 sheets) Dimensions Stirling engine Laura: Base plate: 140mm x 100mm Flywheel: 80mm Total height: 105mm Working piston: 10mm Displacer piston: 13mm To build the Stirling engine "Laura" material set, you will need a small lathe, a small drill and a gas burner for soldering small parts.

Our model Rufus is a model of a thermoacoustic Stirling (Lamina Flow Stirling). The construction of the thermoacoustic Stirling engine is very simple. In Rufus, the working piston is moved by a thermoacoustic effect. A thermoacoustic effect occurs when air is heated in a tube and caused to vibrate using an exciter source (e.g. steel wool) so that a standing wave is formed in the tube (Rijke tube). As with the Stirling engine, there is also the cycle of expanding and contracting air (gas). A comparison with the Stirling engine is also possible in that it is a closed system, although the thermoacoustic Stirling does not use a displacer piston. This is what makes the design of the engine so simple. The thermoacoustic Stirling engine Rufus runs almost silently. It is heated with a small burner filled with spirit. The working piston is made of graphite and does not need to be lubricated. The Stirling engine 'Rufus' material kit is constructed according to the well-known BENGS model building principle. All milled parts are prepared to such an extent that they only need to be deburred and possibly drilled. The turned parts are unprocessed. The flywheel can also be made on a small lathe. The scope of delivery includes: Finished milled parts Raw material for the turned parts and graphite pistons Raw material flywheel (aluminum) Milled wooden base plate made of oak Material for the burner All required screws, nuts, glass tubes, fiberglass wick, ball bearings and O-rings Construction plan Stirling engine Rufus drawings (6 sheets) and construction instructions (2 sheets) Dimensions Thermoacoustic Stirling engine Rufus Base plate: 170mm x 100mm Flywheel: 60mm Total height: 88mm Total length: 255mm Working piston (graphite): 18mm To build the thermoacoustic Stirling engine Rufus material set, you will need a small lathe (min.

Otherwise, hand tools, which should be in every “steam engine workshop”, are required (M2 tap, 3H7, 6H7 reamer, files, drill set, screw locking adhesive). 

Valve-controlled steam engines are certainly among the most impressive machines. Since the valve control is attached to the outside of the cylinder, the process can be observed very well. The centrifugal governor increases the number of moving parts even further. A slow-running valve-controlled steam engine with a centrifugal governor is a real treat for every model maker.With this material kit you get, as usual, all the parts you need to make this beautiful valve-controlled steam engine. All milled parts are already milled. All turned parts are included in the kit as raw material and must be made by you according to the drawing that is also included. A valve-controlled steam engine has a particularly impressive control system. The distribution of the steam is not controlled by a compact valve but by 4 individual valves. Each of the valves has its own eccentric. In our machine, the centrifugal governor controls the speed by accessing the valve rods and limiting their travel. The model With this material kit for the valve-controlled steam engine ‘Isabel’, you can build a very complex valve-controlled steam engine. The kit has a stable machine base made of sheet steel. The majority of the engine parts are made of brass. The 4 eccentrics of the steam engine are driven by 2 brass bevelled wheels. The centrifugal governor is driven by two diagonally toothed brass gear wheels. It can be used to regulate the speed of the steam engine. The cylinder of the valve-controlled steam engine is made of brass, the piston and plain bearing bushes are made of bronze. The 140mm flywheel is made from a very cleanly cast steel casting. The base plate is laser-cut from 1.5 mm sheet steel that can be easily bent by hand. All other parts are made of brass, as proven in steam modelling. The following is required for construction:To build the horizontal steam engine you will need a lathe, a small drill and a gas burner for soft soldering.

The Leni steam engine is a model of a standing steam engine with Stephenson reversal. With its 80 mm flywheel and a total height including the base plate of 185 mm, the model is a good size so that it can also be manufactured in smaller model workshops. This type of steam engine was built from around 1840 until the 20th century. This standing design often found its place in small craft businesses where it powered various tools or generators. The direction of rotation of the steam engine can be changed at any time using the Stephenson reversal. The construction plan and instructions for this standing steam engine are very extensive, detailed and easy to understand. This makes the kit not only suitable for model building professionals but also for newcomers to technical model building. The construction instructions go into the production of each component. In addition to the detailed printed instructions, you will also find a comprehensive construction report of the Leni steam engine in our Bengs model building magazine.

The 2 cylinder steam engine Tobias with Stephenson reversing is an impressive model of a standing 2 cylinder steam engine, as it often was used in steam ships or stationary systems. The Stephenson reversing system can be used to reverse the direction of rotation of the machine by turning the handwheel. The model already runs from 0.5bar. At low speeds, the impressive movements of the steam engine can be observed very well. The movement sequences of the Stephenson control system are particularly impressive. This model is not suitable for entry into steam model construction. Because of the very complex structure, you should first learn the basic principles of the steam engine with a slightly simpler model. As with all material assemblies, all milling parts are finished milled with this kit. The rotating parts are included as a material section and still have to be machined by you.

Our eccentric press is a replica of a machine tool that was used many years ago in many craft and craft industries. industrial companies could be seen. Eccentric presses were previously used for punching holes and embossing work. Originally the presses were driven via a transmission. Later  Many of the eccentric presses were subsequently equipped with an external electric motor. The actual belt drive was retained. Our model is a replica of such a press. It is equipped with a punching tool with a diameter of 5.5 mm, which corresponds exactly to the diameter of an office hole punch. The press must be powered by either a steam engine or a small electric motor. The best way to do this is to use a small round belt that acts directly on the large flywheel. The flywheel and gearbox are constantly running, but the tool is not yet moving. The model has a foot lever that operates a clutch that allows exactly one work cycle. When the foot pedal is pressed, the clutch engages and the tool moves downwards. The stamp punches the hole and then returns to its original position. Here the clutch is automatically disengaged. Most of the model's components are made of brass. The large machine base is laser cut from steel. All axles are made of silver steel. All milled parts are included in the kit ready-machined. All turned parts are included in the delivery as raw material. Of course, as with all other Bengs model building material kits, you will also receive all the screws, nuts and springs you need. To the construction  A small lathe and a column drill are required, as well as a gas burner for soft soldering. The following should also be available: Tap M2, M3, Dies M2, M3 Reamer 5H7 files and a drill set. Otherwise, hand tools, which should be in every “technical model making workshop”, are necessary.   Here you will find an extensive construction report for the Nils eccentric press material kit with lots of pictures and tips.

If desired, you can also use this dynamo as a historical electric motor by simply supplying it with 12 volts. The model is based on a historical generator. The open design means you can see very well into the generator. The collector and the brusches are also outside and are very clearly visible. Of course, this generator has the obligatory eye screw in the upper part of the housing. The generator also stands on 2 tensioning rails to optimally adjust the belt tension. The complete dynamo can be moved 10 mm on the tensioning rails The material kit is mainly made of brass. The motor housing is made of aluminum. The armature with the winding and the magnets are taken from a standard electric motor included in the kit. The electric motor will be dismantled according to your instructions and some of the components will be reinstalled. Comprehensive construction instructions are included for the further steps in building the generator. In addition, you will find a detailed Construction report with lots of pictures and explanations. The generator runs very smoothly and has little resistance, making it also suitable for smaller machines with little power such as flame eaters. Accordingly, the power output is not particularly high. However, it is enough to light up a small 6 V light bulb or to operate several LEDs. All milled parts are already milled and may still need to be drilled, all turned parts are included in the kit as raw material.

This crane is a replica based on a real harbor crane from England. The model of this crane is located on the edge of a canal in Driffield, East Yorkshire, Great Britain. This crane used to be used to lift goods from ships and even entire boats out of the water. The original and model have a gear with which the chain could be moved either in rapid motion or slowly with a lot of force. The crane has a brake so that the chain spindle does not unroll itself when a load is hanging on the hook. The brake has an integrated freewheel so that the braking force only works in one direction of rotation. When you crank a load up you don't have to overcome the braking force. The crane is rotated via a second spindle with a worm wheel. All milled parts in the model are made of brass. The intermediate columns and the rotating columns are supplied as free-cutting steel. The brake drum and idler pulley are made of gray cast iron. A round rod made of oak is included for the boom. The model is fully functional when assembled and can lift and hold loads of up to 250 g. If the base of the crane were to be enlarged even larger loads would not be a problem. The scale of the harbor crane is approximately 1:20.  All milled parts are included in the kit ready-made. All turned parts are included in the delivery as raw material. Of course, as with all other Bengs model building material kits, you will also receive all the necessary screws, nuts and a suitable chain. The base made of 4 mm sheet steel is included as a laser-cut sheet metal part. To the construction  A small lathe and a column drill are required, as well as a gas burner for soft soldering. The following should also be available: M2, M3, M4 taps, M3 dies, 4H7, 6H7, 8H7 reamers, files and a drill set.

With this material kit you can make a blowtorch yourself. The blowtorch is model size and has a total height of 125 mm. The blowtorch is mostly made of brass. The handle and the handwheel for adjusting the flame size are made from the included oak wood. The finished blowtorch also works in the model just like an original blowtorch. You can use the torch for brazing, soft soldering, paint stripping and for operating glow tube igniter engines. Of course, this beautiful blowtorch is also suitable for the model making display case just to look at. A blowtorch is a gas burner that was originally powered by gasoline or spirit. The blowtorch is not only used for soldering but also as a heating lamp for preheating glow-head engines. An alcohol-powered blowtorch does not start by itself but must be preheated. Due to the complicated handling, spirit and gasoline-powered blowtorches were replaced in the 1970s by blowtorches with butane as a fuel. The alcohol-powered blowtorch remains a fascinating tool to this day.  All milled parts and all stamped parts (tank base and tank cap) are included in the kit ready-made. All turned parts are included in the delivery as raw material.

The finger engine Empire has been specially designed by us so that the material kit can be worked, assembled and painted in less than 6 hours. Therefore, the pedal machine is very good if you want to give a close relative, a good friend or a good model builder a model you have built. Of course, the "Empire" can also build for themselves. The "Empire" finger engine is a great model for the desk of every technology fan. By moving a finger up and down, we press the pedal and bring the machine to life. The machine is held in motion by actuating the drive pedal. The constant actuation of the finger pedal has a very calming effect on the user. In addition, we recommend using the pedal machine during long telephone conversations to increase the well-being (guess of the designer). The finger engine is held in the Art Deco style of the 1920s. The finger engine is mounted on a Jatoba base plate The skin wave is ball bearing. Most components of the Empire are made of brass. The flywheel is made of cast steel.
