Sphere on a mini lathe
First method of making a sphere using NanoEls H4 metal lathe controller. With ellipse mode, we first make the right hemisphere and then the left one.
There are many other ways to make a sphere using H4, let me know if you're interested in those :) Also a whirligig, an egg, a mushroom... 😄
