Article note: _Almost_ that spherical robot that is always lurking in a corner of my brain. \nThe hobby servos and 90Deg gearing are kind of limiting and the manual Z is sketchy, but the lazy susan bearings and general drive layout are super clever.<\/div>

It is the time of year when a lot of people in certain parts of the world carve pumpkins. [Gonkee] is carving a watermelon, which we assume is similar. He decided to make a CNC machine to do the carving for him. The unusual part is the use of two lazy Susans to make a rotary carving machine<\/a>. You can see the result in the video below.<\/p>\n

The hardware is clever and there is software that lets you do drawings, although we were hoping for something that would process gcode or slice STL. That would be a worthy add-on project. There were a few iterations required before the Melon Carver 3000 worked satisfactorily. Seeing a carving tool operating on two circles gives us a lot of ideas. We aren’t sure how sturdy the mounts are, so don’t plan on carving aluminum without some changes, but we suspect it is possible.<\/p>\n

Then again, a laser head mounted on the frame would have probably made short work of the melon, and wouldn’t require much mechanical stiffness. It would, however, take a little effort to keep it in focus. So many ideas to try!<\/p>\n

Watermelon is a popular hacking medium<\/a>, apparently. There’s even one that holds a GameBoy<\/a>.<\/p>\n
