Stationary engine Karl with Hit & Miss regulation
€545.00*
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. The cylinder is made from a hydraulic cylinder tube which is already finished on the inside and has an excellent surface. The cylinder head and cooling jacket are made of aluminum to guarantee good heat dissipation. The flywheels are made of cast steel in the usual Bengs model construction quality. Most attachments and machine frames are made of brass.
All necessary materials for the construction of the internal combustion engine "Karl" Screws, springs and ignition parts are included in the kit. All milling parts are prepared so that they are only deburred and possibly drilled.
Construction of the Hit & Miss engine requires a lathe, a drilling machine and a gas burner for soldering. Furthermore, the following hand tools still needed (taps M2, M3, M4, M8x0,75, M10x1 Dies M2, M3, M4, M8x0,75, M10x1 Reamer 3H7, 4H7 6H7, 10H7) files and a set of drill bits needed. Only one side cutter requires a stripping plier and a soldering iron for wiring the ignition.
If you want to find out in advance what steps need to be performed in the production of this engine that you see in our Bengs model magazine the building report from the 4-stroke stationary engine "Karl" on. On this page you can see the illustrated report how the station motor is edited.Included in the delivery are:
Finished CNC milled milling parts
Raw material for the turned parts
Raw casting for the flywheels
Raw casting for the belt pulley

Drawings Internal combustion engine "Karl" (24 sheets) and english construction manual (11 sheets)
Wooden box for ignition

Hit & Miss regulation
The Hit & Miss regulation can limit the engine's maximum speed. 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.
Taps DIN 371
€11.60*
Thanks to their square grinding, our machine thread drills are also suitable as hand-held tap drills. You have the choice between through-hole tap drills (blind hole drills) and basic drill tap drills. The through-hole tap is suitable for through holes where the chips can fall out. Taps for through holes have a longer cut but are more stable than basic hole drill.
The ground hole drills are ground with a right-hand twist, which causes the chips to be ejected upwards, which is of course an advantage for ground holes. They have a very short cut to cut the thread as far as possible into the bore and to create a thread that is as long as possible. However, it should be noted that the stiffness of the taps is significantly lower in the case of the sizes M2 and M2.5. The taps are made of HSS steel and are suitable for threading in steel, brass, plastics, copper, cast steel, aluminum and stainless steel. If you always use sufficient cutting oil during the thread cutting, the service life of the taps is considerably increased.
Particularly when cutting small threads in model construction such as M2, M2,5 or M3, we recommend our round winder. This allows a safe and accurate cutting of threads with a clearly reduced risk that the tapping tool breaks.
If you want to drill a core hole but do not have a table book or a thread table, this is no problem. There is a simple rule of thumb for metric control threads. Just take the diameter of the tapping tap times 0.8. Example M5 = 5mm diameter x 0.8 = 4mm core hole drill.

Hot steam oil
€5.70*
This hot steam oil for model building is ideal for the operation of real steam models. The hot steam oil is very viscous and also adheres very well to hot components. When a model steam generator is operated with steam, normal oil (for example, fine mechanics oil) is washed out very quickly by the steam. Since the hot steam cylinder adheres very well, it remains in the cylinder, the piston and the piston rod for a long time. You can also use the hot steam oil in our displacement oil.
Due to its viscous nature, the hot steam oil is not suitable for lubricating Stirling engines or flame eaters.

Tip
high-alloyed silver solder 1mm / 1,5mm
€4.70*
We have silver braided bars with a silver content of 55% (L-Ag55) with a length of 500mm. Because of the relatively low melting point of this silver braze, the model builder in the field of technical model building is almost exclusively concerned. The working temperature of this hard solder is 630 ° C. The silver as an alloying component in the solder does not only reduce the working temperature, but also improves the flow properties. Furthermore, silver has the positive property of combining well with other metals. For brazing brass and steel, silver solder flux is essential. The low working temperature of the silver solder bars allows the thermal load to be as low as possible for the processed material. It is important not to heat the workpieces too much, especially in the case of brass. In combination with our silver solder flux you achieve with these silver solder always optimal results.
The silver braided bars can be purchased from us in the shop in 2 different diameters. For fine soldering as it often happens in technical model construction we recommend the 1mm rods. The 1mm silver braided bars are easy to carry with the hand and can be easily melted with small burners. For larger parts we prefer the 1.5 mm silver solder bars. With these rods you get faster material to the soldering point if needed. What can be brazed?The following materials can be combined with silver solder: brass, copper, gunmetal, gray cast iron, rusting steels and stainless steel. A combination of the materials among each other is easily possible with this silver braze solder. If the material is not known to you, it is always recommended to solder a piece to the sample beforehand. This allows you to determine whether the materials can be combined with the silver braze.Instructions Brazing with silver solder
If you have never worked on silver solder and you are not sure how the exact solder brazing procedure is with silver solder, we can help you before you buy the silver solder. We have created a guide for you in our Bengs Modellbaumagazin on the topic "Brazing with silver solder". Here you can find out what you need and have to consider if you want to solder 2 components with silver solder.
Tip: Flux residues and discoloration of the material can be optimally eliminated with our satin brushes or abrasive fleece!Characteristics of the silver solder bars500 mm long.
