Michael will share his hard earned knowledge gained from forty years of experience through his extensive power point presentation with over 200 photos that focus on dozens of examples of those issues, both before and after a rebuild, that are unique to the most common Herschede Tubular Bell movements.  This is not a simple discussion of disassembly, restoration and reassembly but an in depth look at all the problems associated with these high quality but often troublesome movements.  Just a few of the topics include the dead beat escapement, anchor replacement, bushings, polishing and adjusting of levers and pins, hammer dampers, the chime cylinder, chime lift lever, gathering pallet adjustments and replacement, rack hooks, minute wheel issues, the main wheels and maintaining power system, cable replacement tips, self adjust chime adjustments, delivery and installation tips, parts availability, pricing concepts and repair times as well as special considerations for the two weight Herschede tubular bell clock.    The class will also include an actual demonstration of restoration techniques on a Herschede tubular bell movement. 

Attendees are encouraged to bring any Herschede movement they may have for inspection or possible trouble shooting help.
