Скачать или смотреть Making Small Ball Handles

This video shows how I made ball handles using ezNC and a Sherline lathe. The main gcodes are generated by FreeCAD and LibLathe. Gcodes for the (big ball tip) clean up cut are manually edited, and basically just a few G3 commands.


The ball handles are cut from 1/2" stock. To safely cut this with such long over-hang, ER20 chuck is the best choice. Please see my other video on how to make one using ezNC. One can get by with an ER16 chuck, but needs to cut part of diameter down to fit in ER16.



The shape is not perfect spherical. But that's not caused by the backlashes from my cheap DIY Sherline CNC conversion. It is because I don't know how to persuade LibLathe to compensate the shape of my hand ground cutter. If you know how to do that, please drop me a message. I'd be happy to buy you coffee or donate tools.
