Here it is, with the angle at zero, 90, 180, and 270°. The yokes move in and out, letting you read values of Sin and Cosine for each angle. The teeth around the bevel edge are 1° apart from peak to vally, ie there are 180 teeth. I would have liked to post this as an animation, but my version of Alibre does not have that feature.
We're thinking this might be helpful when the kids need to learn Trig. We're also planning to paint it up and hang it on the wall.
