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.

High temperature soft solder with a melting point of 250 ° C is suitable for fittings, pipelines and components on steam engines, Stirling engines and flame eaters. The soft solder is filled with a flux that burns without residue when flame brazing (flux residues must be removed in the case of piston soldering !!!). If you need additional flux, you can use normal soft solder flux. Due to the increased melting point of 250 °, it is a good alternative to brazing. However, the high-temperature softening braze can not replace brazing. This product should not be used in the vicinity of the boiler. The use of silver solder is recommended. Wire diameter: 1mm Wire length: 1000mm This product is unleashed !!!

When brazing, fluxes have the task of loosening and removing the oxide layers present on the soldering surfaces and preventing them from forming again during soldering. The flux is adjusted to the working temperature of our Silver hard solder matched. Before use, the flux for silver solder should be stirred well. Using the brush in the bottle, a thin layer can be applied to the component to be soldered. You can find detailed instructions in our model making magazine (Hard soldering with silver solder instructions). If the silver brazing flux has dried out, you can make it liquid again with distilled water. Brazing with silver solder rods without flux is not possible. When the flux is heated with the burner, the water it contains first evaporates. This can be seen in the final formation of small bubbles. When the component is heated further with the flux and the working temperature is reached, the flux paste begins to melt and becomes transparent. Now the moment has come where the silver solder can be added. The effective range of the flux for silver solder is between 500°C and 800°C. The flux is suitable for brazing copper, brass, gunmetal, steel and stainless steel. Tip: Flux residues and discoloration of the material can be optimally removed with our Satin brushes or remove with abrasive fleece. You can get the flux for silver solder from us in the packaging sizes: 50g. Bottle with brush 100g.Bottle without brush

Our powder coating systems are very often used in the restoration of old motorcycles or cars. With this system it is possible to coat entire motorcycle frames or rims with powder varnishfor coating. The result is indistinguishable from industrial powder coating. Powder coating is also very often used in technical model making because the finished surface is extremely robust, scratch-resistant and provides good corrosion protection. Application examples powder coating of vintage car parts Powder coat motorcycle parts Powder coat rims Powder coating of small parts in technical model making This powder gun is a Tribo powder coating system. The powder becomes statically charged in the barrel of the gun due to the friction on various materials. The device is connected to the earth conductor of the socket via a ground terminal and a Schuko plug, which means the component is grounded. Due to the electrostatic charge generated during the run, the coating powder adheres to the workpiece. This effect allows you to coat a variety of materials. The charging occurs when the powder particles touch the wall of the barrel of the powder gun, causing electrons to be released from the Teflon™ barrel. The powder paint particles are separated from the spray gun faster than the charge can be redistributed. This means that the powder particles remain charged and stick to any material. You do not need any additional electricity for the tribo process. The included plug is only the ground connection of the device. Power Coat 4 PRO can process all coating powders that are suitable for Tribo systems. Here in our online shop you will find suitable spare parts for the powder coating system. p> Coating wood, tiles and glass In contrast to conventional powder coating systems, this powder gun coating system can also be used to coat wood, tiles and glass. Since these materials are not conductive, the ground terminal cannot be connected here. This makes applying the powder a little more difficult. You should first make a sample to test the properties of the material and its behavior during powder coating. What else is needed (not included) Compressor Extension hose oven for burning (min. 200c ° from a small household oven to our)

JB Weld is considered to be the strongest glue in the world! It was developed 30 years ago in the USA and sold millions of times. It is located in almost every household. The 2-component epoxy resin adhesive is universally applicable and creates truly durable connections. With this adhesive, metallic materials such as cast iron, gray cast iron, steel, aluminum, brass, bronze, copper and tin can be cold-welded. The all-purpose adhesive also unbreakably combines wood, glass, ceramic or plastic. J-B Weld sticks everything - permanently and super fast. The all-purpose adhesive consists of 2 components. On the one hand there is the hardener (also called activator), in the red tube, on the other hand the part called by the manufacturer as "steel" in the black tube. This is made of epoxy resin and some other components. Both components are mixed together in equal proportions, whereby the reaction process of the curing (polymerization) is initiated. After mixing the 2 components, JB Weld can be processed for 25 minutes. After 8-15 hours, the adhesive is fully cured. Now, as if it were metal, it can be painted, painted, sawn, doweled, sanded or sanded. JB Weld does not shrink and tear during the curing process. A clean adhesive tape remains clean (as with soldering or welding), a smooth surface remains smooth. This makes JB Weld ideal where high-precision work is required. In the commercials of the manufacturer it is advertised that this all-purpose glue can reliably stick cracks in engine blocks.

This hot steam oil for model building is ideal for the operation of real steam models. The hot steam oil is very viscous and also adheres very well to hot components. When a model steam generator is operated with steam, normal oil (for example, fine mechanics oil) is washed out very quickly by the steam. Since the hot steam cylinder adheres very well, it remains in the cylinder, the piston and the piston rod for a long time. You can also use the hot steam oil in our displacement oil. Due to its viscous nature, the hot steam oil is not suitable for lubricating Stirling engines or flame eaters.

With this powder coating machine, you can easily apply powder coatings to materials such as metal, non-ferrous metals and aluminum. In addition, you can also use the powder coating system to coat non-conductive materials such as ceramic or glass powder coated. The special feature of this powder coating device is that the powder is only statically charged and no high voltage is required. This powder coating plant does not require a power connection. All you need is a compressor. With this device, you are able to produce a professional powder coating in your own workshop. A powder-coated component is significantly more robust and durable than a painted component. This powder gun is a tribo powder coating system. The powder is statically charged by friction in the course of the gun. Electrostatically charged, it adheres to the workpiece. Through this effect, you can coat a variety of materials. Charging is effected by the powder particles touching the wall of the barrel of the powder gun, thereby dissolving electrons from the Teflon ™ barrel. The separation of the powder lacquer particles from the spray gun takes place more quickly than the charge can redistribute. As a result, the powder particles remain charged and stick to any material. You do not need any additional electricity for the Tribo process. The enclosed plug is only the earth connection of the device. Includes: AlPowder coating gun with EU (Schuko) ground plug 250ml powder container Funnel for a simple loading of powder into a powder cup 14 page user guide in English with multiple pictures that will guide you through a powder coating process safely. Powder coating is the process when powdery plastic particles (usually polyester or polyuretan) are electrostatically applied to a clean metal surface using a powder coating device. The process is used throughout the industry to create a durable, professional finish. The principle is quite simple, after the preparation and the degreasing of the component, the powder is positively charged by the gun. Similar to a TV screen attracts dust, the component now attracts the charged powder cloud. In the next step, the powder-coated component is placed in an electric furnace. Please note that the oven is no longer used for food preparation. Most powders require about 15 minutes of baking at 180 ° C. The average time from the powder coating to the ready-to-install component takes about 30 minutes.  What else is needed (not included in the set) Compressor with pressure regulator extension hose Oven alternatively small pizza oven FFP2 protective mask safety goggles Well ventilated workplace Advantages of coating: Extremely robust and abrasion resistant Without drying time immediately ready for use Optimal corrosion protection Environmentally friendly as there are no solvents Absolutely uniform surface quality Elastic coating e.g. For springs

The Flame eater oil from Bengs Modellbau is particularly suitable for lubricating the pistons and cylinders of flame-eaters in technical model construction. The flame-eater oil is an oil, based on white oil. It is liquid as water, odorless and biodegradable. Another important advantage of our Flame-eater oil for use in technical model construction is that it does not attack paints and varnishes. When the flame eater or parts of the flame eater exceed the temperatures of 150 ° C, the flame-eater evaporates and produces a beautiful white smoke. The oil we offer is normally used in the aircraft RC model building as smoke oil.   Many oils leave behind residues in the hot vacuum engine, which cause the piston to run smoothly in the cylinder. Likewise, when lubricating with graphite powder, deposits of graphite dust are produced over time, which lead to the piston becoming dull. These residues must be removed from time to time. For a long time we asked ourselves:   Which oil is best used for a flame eater or vacuum motor? And here is finally the solution! Flame eater oil from Bengs Modellbau. With the oil from Bengs Modellbau you do not have the described disadvantages and also the following advantages:   Flame eater oil is liquid like water   Odor neutral biodegradable It does not attack lacquers Best suited for technical modeling Made in Germany No dangerous good according to UN, IMO, ADR / RID, IATA / ICAO.
