Here is a short video of the Rotary Jig in action. It was made with the cover off the machine so the carving action could be seen.
No, I don't recommend that anyone remove the machine's top cover. This short video was made when I was using my old prototype jig, so it doesn't LOOK like the current jig, but functions the same.
