What is circular besides drum heads and cymbals? (and besides, scaling and transferring drawings this way is terribly retro) Windows can be circular, game boards could be circular.

But why the tape? why does this need to be carefully taped/registered in place?

Something to do with checking the area of rectangles or other shapes? Some type of measuring device?
