I've been making rolled stars by hand for about a year. The technique I have been using is good, if you don´t want to spend money (only a bucket is needed). But to make a 100 g batch I had to spend more than an hour in the process. So I surfed on Internet to find how to make one of this gadgets. I discovered that wiper motors have the perfect speed for this purpose. So I bought one of them for 20 bucks, I picked up a few pieces of wood and I built my own star roller in a day. Here some photos of it.
The frame is very simple: A pair of wood triangles with a 45º angle side, and another wood panel, where a carpenter's square is screwed. This square holds the motor creating a perfect angle to roll the stars.
As you can see in this photo, the motor is connected directly to the bucket.
