Grubless screws are mostly used to attach components such as flywheels, cam disks, eccentrics or adjusting rings to an axle. There is a conical tip at the front end of this DIN 914 set screw. In order to secure against rotation with these grub screws, the shaft must have a small drill hole. Alternatively, you can also use a grub screw with a DIN916 ring cutting edge. The grub screws have a hexagon socket and are made of galvanized steel. These threaded pins are particularly suitable for model making such as Stirling engines, internal combustion engines, flame eaters or steam engines.

With these oak base plates you can visually enhance your steam engines, Stirling engines, flame eaters or combustion engines. We have the basics in different dimensions. The oak panels are also used in our models. The base plates are delivered untreated. They have the look typical of oak, which is particularly effective after oiling.

With these compression fittings you can connect three brass pipes or copper pipes together without soldering. A compression fitting consists of a base body, three cutting rings and three union nuts. All parts of the T-compression fitting are made of brass. The compression fittings can be used in both pneumatics and hydraulics. These screw connections are also used to connect lubrication lines, gasoline lines, gas lines, supply steam lines or exhaust steam lines. The compression fittings are also used in trade and industry. There are even many areas of application in model making. To crimp a pipe, the union nut is first pushed over the pipe. The cutting ring is then also pushed onto the pipe. Now the pipe can be inserted into the base body and the union nut is tightened using a wrench. When the union nut is tightened, the clamping ring is compressed so tightly that it can no longer be removed from the pipe without being destroyed. The following T-compression fittings are available: T compression ring fitting for 4 mm pipe / internal thread union nut M8x1 T compression fitting for 5 mm pipe / internal thread union nut M10x1 T compression ring fitting for 6 mm pipe / internal thread union nut M10x1 T-compression fitting for 8 mm pipe / internal thread union nut M12x1 T compression fitting for 10 mm pipe / internal thread union nut M6x1.5 Suitable Copper pipe or Brass pipe for the compression fitting can be found under the link.

From us you can buy free-cutting steel round material in 300 mm length. We use this material in various models, for example for the crankshaft of the four-cylinder engine “Marc”. The round material can be easily machined on the lathe and on the milling machine. The variants 16mm, 20mm, 30mm and 40mm diameters are currently available. The free-cutting steel round bars are 300mm long.

Lobular screws with hexagon socket DIN7380 have a very flat head and a very nice look. They are suitable, for example, for screwing cylinder covers or gearbox covers. Due to their low height, they are particularly suitable for model building. We deliver the lens screws DIN 7380 exclusively in stainless steel.

This is the flywheel we use for our Jonas combustion engine. The flywheels are manufactured using the lost wax casting process. The advantage of this casting process is that the casting has a very high quality and dimensional accuracy. Voids and hard spots are excluded with the lost wax casting process. The flywheel has a raw diameter of 202mm. The sprues are already sanded. The flywheel is cleaned and sandblasted. It is suitable for use both as a flywheel on a model building machine and as a wheel tire for a cannon or carriage. The flywheel is available in two versions. The first variant is unmachined and needs to be finished by you on your lathe. The second variant is completely finished. You can see the exact dimensions of the finished flywheel when you select the variant in the article images. Dimensions of the flywheels:Raw diameter: 202mm Finished diameter: 200mm Diameter scar: 28mm Width hoop: 30mm Width scar: 43mm Weight: 2.8kg Material: cast steel (not gray cast iron)
