flywheel 80mm heavy

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)

You will find in our shop ball bearings made of steel in different sizes. All ball bearings are offered in the ZZ variant. The double-sided sheet metal disc with gap seal keeps dirt out and guarantees a good smooth running. The ball bearings are very well suited for technical modeling. We use the miniature ball bearings for flame eaters, steam engines and Stirling engines as they are particularly easy to move. Most of the offered ball bearings have a small cross-section to keep the installation dimension as low as possible.   The following ball bearings are available:   Inner diameter   outer diameter width ball bearings 63 ZZ 3mm 6mm 2,5mm ball bearings 106 ZZ 6mm 10mm 3mm ball bearings 688 ZZ 8mm 16mm 5mm ball bearings 6700 ZZ 10mm 15mm 4mm ball bearings 61800 ZZ 10mm 19mm 5mm        

Here you will find model construction screws in various diameters and lengths made of brass. A model bucket with a hex head has a smaller key width and a higher head compared to standard hex head screws. With model screws, you can give your steam engine, Stirling engine or Flammenfresser an authentic appearance. Since the screws used at the time of steam engines or station heaters were similar in proportions. In addition, the smaller heads consume less space on your model machine and they can be placed closer. We recommend that you use our Micro plug to mount the model screws. One packaging unit includes 25 model hexagon bolts. The following model screws are available at any time.

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. 1mm or 1.5mm diameter Silver solder bars L-Ag55 (55% silver) Working temperature 630 ° C Bengs Modellbau has used this silver solder bars for years.
