How I Make Custom Motorcycle Sprockets At Home For Any Chain | CAD to CNC

Описание: Ever struggled to find the exact sprocket tooth count for a custom build? Stop searching for "close enough" sprockets and start making exactly what your project needs. In this video, I walk through my entire process for making custom sprockets at home - specifically for the 2-stage transmission setup for my e-dirt bike. From calculating the critical pitch diameter to milling 7075-T6 aluminum, here is how to get professional results in your own workshop.

In this tutorial, we cover the essentials of sprocket geometry, including why motorcycle sprockets use shortened teeth for high-RPM engagement. I demonstrate how to use SketchUp for parametric-style layout, Prusa Slicer for 3D print testing, and the Makera Carvera Air for milling 7075 aluminum. If you’ve ever wondered how to calculate pitch diameter for a 520 chain or how to use a CNC for making metal parts, this video is for you.
