In March, 2017, I attended my first certified accordion repair seminar in Superior, Wisconsin through the Accordion & Concertina Repair Technicians School and A World of Accordions Museum.
A World of Accordions Museum is huge! Well over 1,000 accordions dating back to an original patented by Cyrill Demian in 1829. An incredible amount of historical documentation on accordions throughout the world. What a great place to learn accordion repair!
This basic repair seminar lasted for 3 days, and covered cleaning and introduction to most repairs. We replaced pads, bellows gaskets, patched bellows holes, re-taped bellows, removed treble keys and bass buttons, and even got to wax some reed blocks and pallets! A good overall view of basic repairs.
