Stationary engine Karl with Hit & Miss regulation
€545.00*
Available again from October 2025
If you're interested, feel free to contact us – we’ll gladly reserve a motor kit for you without obligation.
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
Two wooden runners
All required screws, nuts, sprockets and ball bearings
Drawings Internal combustion engine "Karl" (24 sheets) and english construction manual (11 sheets)
Wooden box for ignition
Ignition coil, condenser, spark plug and breakers
All required cables for the ignition
Power supply for the 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.
