Interesting idea for turning parts

 An interesting idea for turning parts I came across an interesting way of processing products on a lathe. Watch the video first and then see what the idea is.
As you can see, on the template, installed in the lathe, the outline of the desired product is displayed.
The person who came up with this method has just started his steps in woodworking and has very little experience. To order, he needed to make chess pieces. While grinding the pieces, there was a problem in making the pieces the same (pawns, bishops, etc.).
Then he thought about trying to project the image onto the workpiece and grind the figures from the projection.
A projector was purchased for this purpose.

The artist tested the image on the wall. Of course, the quality was not very good, but all that was needed was a silhouette projection. He found that 1200mm is the closest acceptable distance.
It is clear that the closer the projector is, the brighter the projection will be, given that the turning of parts is carried out in a bright room.
He set the contrast and brightness to 100% and the color and tint to 0%. These settings made the image almost monotonous, but only a silhouette is needed here.
After determining the distance, the projector was mounted on the wall above the lathe.

To align the image on the workpiece, a center line was drawn along the axis.
