Radial Engine, 7-Cylinder, Optional Parts Kit

cults3d

This kit is designed to include the Motor Drive Device as an option for my next model. https://cults3d.com/en/3d-model/tool/radial-engine-7-cylinders-cutaway In this design, there are several areas that create unavoidable rotational drag, and if it's too severe, driving by the motor may be challenging. However, if the engine is rotated gently with a finger, it can be driven by the motor. The largest source of drag comes from friction between the No.1 and No.5 cylinders and the piston. It's crucial to smooth out the layer step on the inner diameter of the cylinder and the sharp edge of the outer diameter of the piston and the layer step. In my case, I was able to drive the motor without using grease. Nevertheless, I cannot guarantee that everyone will be successful, so please only attempt this for those who are confident in their skills. A.
