I am “twitter-building” a concertina in (sort of) real time:

I’m following that with a great interest & saving everything in a pdf. Very beatiful instruments you make!
I did the same with Wim Wakker’s at Concertina Connection and it’s funny how different are methods to achieve the same instrument
Anyway, I prefer your method… always liked more good craftmanship that machines!

Very cool Bob! I now have a new appreciation for this little instrument and understand why a good one demands such a high price. I just read through the first 7 installments and am looking forward to the next one. I’m impressed that you had to teach a lot of the process to yourself. It certainly looks like you got the hang of it now. You are a true craftsman.
Very informative and amazing to see a workshop producing such marvelous instruments! I am sure to catch the concertina bug sooner or later, I will definitely be in touch…
