Stirling engine Rainer with centrifugal governor material kit

Machine reamers for the production of dimensionally accurate bores. By rubbing with a reamer, not only good shape and dimensional accuracy, but also good surface quality is achieved. This is of crucial importance when manufacturing sliding bearings in mechanical engineering and model building. The long cutting edges of the reamer have a left-hand twist, which causes the resulting chips to be discharged downwards when rubbing. Thus, a scratching of the bore surface by the resulting chips is avoided. Our machine reamers have industrial quality and can be used to grind drillings in steel, brass, copper, cast iron, aluminum and stainless steel. Please always use enough cutting oil when rubbing, which considerably increases the service life of the reamer. In model construction, these reamers are suitable for producing piston rod guides for steam engines, Stirling engines and flame eaters. The reamers are also ideal for producing bearing blocks with plain bearings or for producing cylinders with a very clean surface. If you produce the axis bore with a reamer for flywheels, the flywheel runs particularly round. Provided you have the flywheel without impact in the lathe. The machine reamers can be used both on a lathing machine and in a column drilling machine.   With long cutting edges and link spiral Maximum roundness accuracy industrial quality   These reamers are available: Reamer 1H7 / Shaft 1mm / cutting length 16mm  Reamer 1,5H7 / Shaft 2mm / cutting length 21mm  Reamer 2H7 / Shaft 2mm / cutting length 26mm  Reamer 3H7 / Shaft 3mm / cutting length 29mm  Reamer 4H7 / Shaft 4mm / cutting length 46mm  Reamer 5H7 / Shaft 5mm / cutting length 57mm  Reamer 6H7 / Shaft 6mm / cutting length 56mm  Reamer 7H7 / Shaft 8mm / cutting length 71mm  Reamer 8H7 / Shaft 8mm / cutting length 80mm  Reamer 10H7 / Shaft 10mm / cutting length 91mm  Reamer 12H7 / Shaft 10mm / cutting length 110mm  Reamer 14H7 / Shaft 14mm / cutting length 112mm  Reamer 15H7 / Shaft 14mm / cutting length 114mm  Reamer 16H7 / Shaft 14mm / cutting length 123mm  Reamer 18H7 / Shaft 14mm / cutting length 135mm Reamer 20H7 / Shaft 16mm / cutting length 145mm  Reamer 25H7 / Shaft MK3 / cutting length 174mm  Reamer 26H7 / Shaft MK3 / cutting length 178mm 

Hylomar universal Sealant is a permanent elastic sealant. This means that the sealant never completely cures and can be easily dismantled again and again. This is a decisive advantage for the model builder. The sealed components can be dismantled simply and without destruction, as can often occur once in a Stirling engine or a flame eater. You have a further advantage if you use different material combinations brass - steel, stainless steel - aluminum or metal - plastic. The sealant can compensate for the different expansion. Hylomar universal seal has a thermal application range of -50C ° to 250C ° (in the short term, too). The seal is resistant to fuels, oils, water, steam and antifreeze. You can also use the permanently plastic universal seal for sealing the surface as well as for sealing pipe fittings. Hylomar Durable universal Sealant   Base: Polyurethane Colour Blue Thick paste Density: 1.17 g / cm⊃3; Coating thickness: 0.15-0.2 mm Contains: 80ml Temperature resistant from -50 ° C to +250 ° C   Instructions: The sealing surfaces must be clean and grease-free. Hylomar Thinly apply a continuous plastic universal seal on both sides. If the solvent is vented after approx. 10 minutes, the parts can be assembled. After a further 15 min. Be repeated. For single-planked surfaces, one-sided order is sufficient. At room temperature, Hylomar Permanent Plastic Universal is unlimited in duration.

Soft soldering paste for brass, copper, steel and silver steel. The paste is applied thinly to the parts to be tinned and heated with a brazing lamp. For large-area soft soldering, it is optimal to tin- the parts beforehand. For example, we use the paste to pre-tine the cylinder and the mirror when constructing a model steam engine. The tinning paste can also be used optimally as a flux substitute. The soft soldering paste is excellently suitable as corrosion protection for steel parts. Bengs Modellbau uses the zinc paste for steel cylinders with a cooling water jacket. For example in the Flammenfresser Kurfürst. Stirring the paste before use is not necessary! The soft soldering paste may be diluted with water.

This steel pulley has an outer diameter of 58 mm. The belt pulley was made in the lost wax process and thus has a very clean and fine surface. The belt pulley is designed for use on model-building combustion engines, Stirling engines, flame guns or steam engines. On these model machines it can be used either as a belt pulley or as a flywheel. It can also be used as a wheel for a model caravan. The belt pulley is supplied as raw material. Due to the clean castings, processing of the outer surfaces is not absolutely necessary. Dimensions of the 58mm pulley: Raw diameter: 58mm Finish diameter: 57mm Width on the hoop: 20mm Width at the waist: 20mm Diameter of collar: 15mm Weight: 170g Material: Cast steel (no gray cast iron)

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. All milled parts are prepared to such an extent that they only need to be deburred and possibly drilled. 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.
