The Repair and Replacement of an American Strip Recoil Escapement
This two day course will instruct the student on how to repair and replace the recoil strip escapement generally used in an American open spring clock. First, techniques will be taught to restore the escape wheel of bent teeth, wobble and run-out. Then, the student will learn how to restore an existing strip recoil verge for worn pallet faces, worn or loose saddle and crutch. In addition, the instructor will teach the students how to make two new strip recoil verges for their clocks using different techniques. Students will be required to bring a specified list of tools, parts and an American open spring clock with the escapement on an outside plate.
