Practical Gear Cutting for the Horologist Session Two

by

Come to AWCI in our well-equipped machine shop and join David Lindow in the second offering for this practical, hands on class where gearing and gear cutting will be practiced.   Not only will the student learn the basic set ups involved cutting horological gears but multiple approaches to tooling will be explored as well as theory from a practical standpoint.   The student will learn about wheel and pinion engagements and gain a fuller understanding of horological gearing in general.    While the focus of the class will be on making gears and pinions the skills taught will transfer to general repair and improve the success rate of anyone that repairs clocks even if they never plan to cut gears in their shop.

Herschede Tubular Bell Restoration Class

 

August 11-13  2021

Location: AWCI Headquarters in Harrison, Ohio

Cost of class:  AWCI members – $595 Non-members – $745

 

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.

Bio

Michael’s career as a clockmaker began in 1978 when he took a job with a local clock retail shop delivering and setting up grandfather clocks.  This soon led to a five year clock repair apprenticeship.  He eventually established his own shop, Master Clock Repair in Columbus, Ohio in 1994.  Once on his own his hunger to expand his clock repair horizons prompted him to become more and more active with AWCI and its Ohio affiliate, WAO.  Through these organizations he began to attend every available clock class.  This led to becoming a Certified Clockmaker in 2001.   From 2004 to 2011 he served on AWCI’s Education Committee where he helped write the first ever Standards and Practices document for clockmakers, helped rewrite the certification exam and trained to become an assessor for the exam.  He achieved CC21 status in 2010.  He has also served on the AWCI Board of Directors, Affiliate Chapter Chairman, Honors and Awards Chairman, the Board of Clock Examiners and has been President of WAO for four terms.  During his career he has repaired over 40,000 clocks, has often taught classes for both AWCI and WAO and is a published author of over 15 articles in the Horological Times. He has an extensive web site at masterclockrepair.com.
