2 2 B 3 4 4 6 3 3 8 2 8 9.2 4 5 9.3 7 0 The Grasshopper Escapement shown here was designed as a stand alone mechanism to prove out the design, and as such have additional parts to support it and to enable it to function. These parts namly the stand and the pendulum and even the Escapement wheel will not necessaryly be required if you use the design within your own clock design. I have used a short pendulum of 248mm lencth to give a 2 second ossilation. This works for the compact design shown here but would probably use a longer 000mm pendulum for your own clok. The longer pendulum with the 30 tooth escapement wheel would then give you revolution of that wheel per 60 seconds. Thesize of the small weight is very much up to you, and is there to drive the escapement and will vary with different constructions. ITEM NO. PART NUMBER DESCRIPTION QTY.
