Since reading an '80s EAA Sport Aviation article, the 6-piston, 12-cylinder Dynacam aero engine has captivated me, particularly its innovative cam design for two piston rollers that provide the piston with a sinusoidal axial movement. Today, I attempted to recreate this engineering marvel; however, my initial effort lacked precision. To remedy this, I meticulously remodeled the cam and added extra trajectories for the variable section sweep, ensuring utmost accuracy.
