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. Furthermore, hand tools are required, which should be in every "steam engine workshop" (tap M2, M3, M5x0.5, M6x0.75, M10x1 / dies M2, M3, M5x0.5, M6x0.75, M10x1 / reamers 3H7, 4H7, 8H7, / files, drill set).

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. The largest rotating part in the model steam engine Tobias is the flywheel with 50mm raw diameter.

The model of the “Danni” horizontal steam engine consists of a stable frame to which the double-acting steam cylinder is connected. The cylinder of the steam engine is controlled via an eccentric and a round slide. This compact yet powerful steam engine is ideal for operation with a steam boiler, but can of course also be powered with compressed air. If the kit is carefully manufactured and without load, the machine starts running at just 0.1 bar. The “Danni” is also equipped with a cord pulley with two diameters, so that it is also very suitable for driving drive models such as circular saws, drills or hammer mills. The construction plan and instructions for this steam engine are very comprehensive, 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. For the model builder who has always been want to build steam engines yourself Machine "Danni" definitely a good choice.

The cylinder of the model steam engine is made of brass, the piston is made of bronze. Piston rods and sliders are made of stainless steel and the flywheel is made of cast iron. All other parts are made of brass, as proven in steam model making. The flywheel was manufactured in steel casting using the lost wax process, it is extremely precise and cleanly cast. Included in the scope of delivery of the Danni steam engine material kit Milled oak base plate Finished milled parts Brass, bronze, stainless steel and silver steel raw material for the turned parts Flywheel cast steel All required screws, nuts and grub screws Construction plan model steam engine "Danni" drawings (9 sheets) and construction instructions (6 sheets) Dimensions of Danni steam engine Height with base plate: 100mm Length with base plate: 160mm Width with base plate: 100mm Piston diameter: 15mm Piston stroke: 18mm Flywheel D.: 80mm Only a few tools are needed to build the “Danni” steam engine material kit. A small lathe and a small drill are completely sufficient. If you choose the cast flywheel, your lathe should be large enough to turn an 80mm flywheel on the outside. If this is not the case, select the milled flywheel that is already finished on the outside diameter. There should also be a gas burner for soldering larger parts. M2 and M3 taps and M2 and M3 cutting dies are also needed. You also need reamers 4H7, 6H7, files and a drill set.

Vertical Column steam engines were relatively widespread in the period from about 1830-1865. The cylinder is located on a flat machine on level ground. The flywheel and the crankshaft are supported in brackets which are supported by columns. The piston rod is straightened over a wide cross head. The speed was often controlled by means of a centrifugal governor. In addition, a feed water pump supplied the boiler with fresh water. With the material kit for the "Donatus" Vertical Column steam engine, you can build a steam plant yourself. It has all the parts that need a steam system. It has an angle valve with which one can regulate the steam supply. Likewise, the steam engine has a centrifugal regulator, which is driven by bevel gears and controls a control valve via a linkage. The desired speed of the steam engine can be adjusted via a spring and an adjusting ring. A feed water pump is also located on the base plate of the machine. And, of course, not forgetting the heart of the steam system, the beautiful "Donatus" bucking machine. The only thing that is still missing to get this steam system into operation is a suitable boiler or a compressed air connection. The cylinder of the Vertical Column steam engine is made of brass, the piston and the slide piston are made from bronze. The 140mm flywheel is made of a very clean cast cast steel. For the columns of the steam engine are used aluminum pipes which can be polished perfectly. All other parts are made of brass, as has been proven in steam model construction. The base plate can either be ordered as an unfinished panel blank or with a CNC milled tile pattern. All materials, screws and accessories required to build the "Donatus" steam engine are included in the kit. All milling parts are prepared so far that they only have to be deburred and possibly drilled. A lathe, a small drill and a gas burner for soldering are required for the construction of the Vertical Column steam engine. In addition, there is still hand tools, which should be in every "steam engine workshop" (taps M2, M3, cutter M2, M3, reamer 3H7, 6H7, 8H7) files and a drill set. You can find more information on the construction of this steam engine in our model magazine. You will find in our magazine a building report of the "Donatus" Vertical Column steam engine with many pictures and explanatory texts. Thus, you can inform yourself about the construction in advance as well as during the construction phase to find suggestions and support.Included in the delivery are:Finished CNC milled milling parts Raw material for the turned parts Raw casting for the flywheels Milled and pre-rolled belt pulley Machined wooden base plate All required screws, model trees, sprockets and ball bearings Drawings Column steam engine 'Donatus' (19 sheets) and construction manual (6 sheets)Dimensions of the "Donatus" model steam engine:Height with base plate: 280mm Length with base plate: 150mm Width with base plate: 160mm Diameter of pistons: 16mm Flywheel D .: 140mm
