YouTube craftsman Maker B, who enjoys CNC machining, metalworking, woodworking, and leathercraft, has published a new 20-minute video on their channel showcasing the build process of a 4-cylinder solenoid boxer engine. For those unfamiliar with a solenoid boxer engine, it uses electromagnets to pull the pistons, creating a fascinating and functional piece of engineering.
Understanding the Solenoid Boxer Engine
A solenoid boxer engine is a type of engine that operates using solenoids instead of traditional combustion. Solenoids are coils of wire that act as electromagnets when an electric current passes through them. In this engine, the solenoids are used to move the pistons back and forth, mimicking the action of a traditional internal combustion engine. This type of engine is not only a great educational tool but also a testament to the versatility of electromagnetism in mechanical applications.
Maker B’s video is a detailed guide that takes viewers through each step of the build process. If you don’t have 20 minutes to watch the full video, here are the timestamps to help you find specific areas of interest:

Detailed Build Process
The video begins with the creation of the cylinder, a crucial component that houses the pistons. Maker B meticulously machines the cylinder to precise specifications, ensuring a perfect fit for the pistons. Next, the pistons themselves are crafted, followed by the winding of copper wire to create the solenoids. Testing the solenoids is a critical step to ensure they generate the necessary magnetic force to move the pistons.
The crankshaft, which converts the linear motion of the pistons into rotational motion, is then machined. This is followed by the creation of the connecting rods, which link the pistons to the crankshaft. The engine frame is constructed to house all these components securely. Installing the bearing by press fit ensures smooth rotation of the crankshaft.
The back and front flywheels are then made, which help to smooth out the engine’s operation by storing rotational energy. A wooden base is crafted to provide a stable platform for the engine. Finally, all the parts are assembled, and the finished engine is showcased. The video concludes with a demonstration of the engine’s operation, including checking the revolutions per minute (rpm).
