Thread cutting ratchet

This abrasive fleece or cleaning fleece is suitable for cleaning all metallic surfaces, preparing for brazing or soldering. But even after the brazing with silver solder and flux the pads are very good for cleaning the soldering seam. You can use pads for all materials used in technical modeling, such as brass, copper, steel and aluminum. The abrasive fleece has no metallic abrasion and is therefore also very suitable for stainless steel. The cleaning fleece does not leave any marks, so that a subsequent polishing of the components is not a problem. The sanding pads are very durable and can be used very often. Bengs Modellbau uses this cleaning fleece for soldering work regardless of whether brazing or soldering. The abrasive fleece is, of course, also suitable for cutting or milled brass parts. A pack of cleaning fleece contains 10 pads in the size 130mm x 60mm (Made in Germany)

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.

The tap wrench is equipped with hardened clamping jaws and galvanized steel handles. When used in tight spaces, for example in model making, you can unscrew a steel handle. For particularly narrow applications, we recommend a tapping ratchet. You have 2 different tap wrenches to choose from in our shop. You can see which tap wrench fits in the table.

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.
