This tube is a hydraulic cylinder tube. The inside of the tube is very dimensionally stable and wear-resistant. The cylinder tube is suitable as a cylinder sleeve for an internal combustion engine or flame eater. We also use this cylinder tube in our models. We use it for the combustion engine Karl,  Stirling engine "Big Laura" and the Flame Eater Jarne. Due to its high wear resistance, the tube has proven itself as a cylinder sleeve for us.

Brass Ms58 flat material is a very good machinable material. Brass is probably the most widely used material in technical modeling. Which is certainly due to the fact that it can be worked very well. It can be milled, turned, drilled, brazed and softened. Many Stirling engines, steam engines and flame eaters in technical model construction are mainly made of MS58 brass. You can order brass flat material in different thicknesses from 2mm to 6mm here at the Bengs Modellbau Shop. Flat Material Brass Quality: Ms 58 (drilling and turning quality) Strength F45-50 Flat material 50mm wide Length 300mm

These relatively small spark plugs are particularly suitable for model combustion engines. Its metric M10 × 1 thread also fits into smaller cylinder heads. The spark plugs fit into our internal combustion engine and can be used as a spare part. Of course, you can also use the spark plug CM-6 for your own development with our ignition components. Data of spark plug CM-6 M10x1 Key range: 14.0 mm Overall length: 36mm External thread: M10x1 Thread length: 8.6 mm

Cast iron with lamellar graphite. The surface is peeled on the gray cast iron bars. The round bars are a little over-sized. You can also make a 30mm piston with a 30mm diameter. The material is suitable both for the production of pistons or cylindrical sleeves for model-built motors as well as for the production of plain bearing bushes. We use this material for the pistons at the station "Karl". The round material can be perfectly machined on the lathe and on the milling machine and has excellent running characteristics. All round bars are 300mm long.

Brass Ms58 is a very good machinable material. Another advantage of brass is that it is rust-free. It is suitable for turning, milling, drilling and tapping. In addition, it can be well brazed with silver brazing and soldering. These characteristics are very much in line with the technical model builder. Most steam engines, Stirling engines and flame eaters in model making are largely made of MS58 brass. We offer you here in the Bengs Modellbau Shop brass round material in the diameter from 1mm to 50mm.

The Ignition condenser for intermittent ignition is a component which should not be missing. The condenser regulates the strength of the ignition spark. This ignition coil is also installed in the internal combustion engine Karl and can be used as a spare part. You can use this capacitor to create an ignition breaker for model building. This is a solid moped technology that has proven itself over many years. An intermittent ignition is very durable and also times a wrong polung.   Dimensions Capacitor for Ignition condenser Length: 41mm Diameter: 18mm Threaded connection: M4  

Use this Ignition interrupter to generate the spark. You can control the breaker directly via a cam or via a ram. This article is a serial product from the moped technology. This guarantees a good quality, long durability and fast availability. You can create your own ignition system from this interrupter. We also use this breaker in the ignition of our internal combustion engine "Karl". It can also be used as a spare part in this model.   Dimensions of the Ignition interrupter Length: 30mm Width: 30mm Height: 20mm

This ignition coil is suitable for installation in an intermittent ignition. This ignition coil is also installed in the internal combustion engine Karl and can be used as a spare part. In the normal case, this coil is used for ignition in mopeds. However, due to its reliability and performance, it is very well suited for model construction. An intermittent ignition usually works very reliably and can be more easily checked for faults than an electric ignition.   Dimensions of ignition coil 12V intermittent ignition Length: 123mm Diameter rear: 40 mm Largest diameter collar: 48 mm Connection thread: 2x M4    

Square brass in different diameters. This brass is very good machinable and suitable for turning, milling, drilling and tapping.
