Punch numbers

With this small, fine number of strokes, components can be numbered very easily. The punch numbers are available in sizes 1.5 mm and 3 mm. They are particularly suitable for fine components in technical model making. For example, you can use the punch numbers to mark the matching bearing block cover for the respective bearing block. This means that the components are not mixed up during assembly. The beat numbers are delivered in a red plastic storage box. The millimeter information refers to the height of the number, for example the number 8 in the headline set 1.5 mm is approx. 1.5 mm high and 1.2 mm wide.

This honing device is an ideal tool for model makers for honing bores. With the honing device you can significantly improve the surface quality of cylinder bores, for example. The small honing devices are suitable for producing cylinder bores for Stirling engines, steam engines or flame eaters. When working with the honing device, you should always use plenty of cutting oil.  A detailed description is enclosed. The honing device consists of a bolt that is clamped into a drill chuck, two spring flat steels and two movably mounted grinding stones. The grinding stones are pressed evenly by the spring flat steels. The honing device can be clamped into a hand drill or used on a lathe. If the grinding stones of the honing device are worn out, you can of course get a replacement from us. Material reduction 0.01mm to 0.02mm We have been using the honing device in our workshop for years to hone cylinder bores on our flame eaters. Type Whetstones Bore diameter Type A small 2 pieces 12.7mm - 38.0mm Type B medium 2 pieces 17.5mm - 50mm Type C large 3 pieces 35mm - 80mm Type D large 3 pieces 60mm - 90mm

The silver solder wire is suitable for particularly fine soldering points in model making, crafts, industry or jewelery trade. Silver solder wire is only 0.5mm thick and can be very finely dosed. We supply you the silver braided wire as a 5 meter long piece and you can cut the silver solder wire as desired. You can also use this silver solder wire to form rings, for example, which can be used to solder a wave around the shaft during soldering and then only have to heat it with flux. By this process the silver solder is equal in the required place. 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. Brazing flux is essential for brazing brass and steel. Tip: Flux remedies and discoloration of the material can be optimally eliminated with our Satinbrushes! The silver solder wire 0.5 mm is suitable for brazing brass, copper, heavy metals, steels and stainless steel. All materials can be joined together. 1 Packing unit includes 5m 0.5mm silver solder wire Silver solder wire L-Ag55 (55% silver) !!! Cadmium free !!!

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.
