Here it is. This an Excel file based on Guy Aydlett’s math and directions of the Grasshopper escapement.
It has the math stuff done and a section below for rapidly CADing the grasshopper after you have made changes to variables. I could CAD the layout lines in about 2 minutes. The rest is up to the CADer/Artist.
